BDNF belongs to the neurotrophin family and promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. It is a major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. Microglia release BDNF that may contribute to neuroinflammation and neuropathic pain. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. POst translation modification: Converted into mature BDNF by plasmin (PLG). SIMILARITY: Belongs to the NGF-beta family.

TrkA is a member of the neurotrophic tyrosine kinase receptor family. It is a membrane-bound receptor that upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. TrkA is required for high-affinity binding to nerve growth factor (NGF), neurotrophin-3 and neurotrophin-4/5 but not brain-derived neurotrophic factor (BDNF). TrkA leads to cell differentiations and may play a role in specifying sensory neuron subtypes. It has a crucial role in the development and function of the nociceptive reception system as well as establishment of thermal regulation via sweating. SUBUNIT: Exists in a dynamic equilibrium between monomeric (low affinity) and dimeric (high affinity) structures. SUBCELLULAR LOCATION: Cell membrane; single-pass type I membrane protein. Endocytosed to the endosomes upon treatment of cells with NGF. ALTERNATIVE PRODUCTS: 2 named isoforms produced by alternative splicing. Both isoforms have similar biological properties. TISSUE SPECIFICITY: Isoform TrkA-II is primarily expressed in neuronal cells. Isoform TrkA-I is found in non-neuronal tissues. Mutations in TrkA have been associated with congenital insensitivity to pain, anhidrosis, self-mutalating behaviour, mental retardation and cancer (Reference: www.uniprot.com).

Required to maintain individual mitotic chromosomes dispersed in the cytoplasm following nuclear envelope disassembly (PubMed:27362226). Associates with the surface of the mitotic chromosome, the perichromosomal layer, and covers a substantial fraction of the chromosome surface (PubMed:27362226). Prevents chromosomes from collapsing into a single chromatin mass by forming a steric and electrostatic charge barrier: the protein has a high net electrical charge and acts as a surfactant, dispersing chromosomes and enabling independent chromosome motility (PubMed:27362226). Binds DNA, with a preference for supercoiled DNA and AT-rich DNA (PubMed:10878551). Does not contribute to the internal structure of mitotic chromosomes (By similarity). May play a role in chromatin organization (PubMed:24867636). It is however unclear whether it plays a direct role in chromatin organization or whether it is an indirect consequence of its function in maintaining mitotic chromosomes dispersed (Probable).

Monoclonal antibody MC192 against the rat low affinity nerve growth factor receptor (p75NTR) is derived from the fusion of Sp2/0-Ag 14 myeloma cells with mouse immune splenocytes. MC192 monoclonal antibody was originally generated by Chandlers et al. p75NTR was originally discovered as a low affinity nerve growth factor receptor. Later it was found that it was the receptor for all neurotrophins. It mediates signals of neurotrophins for neuronal survival, apoptosis, neurite outgrowth and synaptic plasticity. Recently, it has been revealed that p75NTR not only acts as the receptor for neurotrophins but also the receptor for many other pathological ligands such as prions, rabies virus and amyloid beta. p75NTR also acts as a co-receptor for NOGO which mediates inhibitory signals of myelin associated protein. p75NTR is highly expressed in a number of non-neuronal and neuronal cells including motor neurons during development and also in damaged neurons. MC192 has a potential use as the ligand for gene delivery into p75NTR-expressing rat cells via a receptor-mediated mechanism.
This antibody reacts with rat only. Does not react with mouse or human NGFR

The amyloid beta peptide is derived from the cleavage of the Amyloid precursor protein (APP) and varies in length from 39 to 43 amino acids. However, the form(s) of amyloid-beta peptide (Aβ) associated with the pathology characteristic of Alzheimer’s disease (AD) remains unclear. In particular, the neurotoxicity of intraneuronal Aβ accumulation is an area of considerable research and controversy principally because antibodies thought to be specific for Aβ have been shown to actually detect intraneuronal APP and not Aβ exclusively.

MOAB-2 (mouse IgG2b) is a pan-specific, high-titer antibody to Aβ residues 1-4 as demonstrated by biochemical and immunohistochemical analyses (IHC), and is highly specific just to amyloid beta peptide. MOAB-2 did not detect APP or APP-CTFs in cell culture media/lysates (HEK-APPSwe or HEK APPSwe/BACE1) or in brain homogenates from transgenic mice expressing 5 familial AD (FAD) mutation (5xFAD mice).

Using IHC on 5xFAD brain tissue, MOAB-2 immunoreactivity co-localized with C-terminal antibodies specific for Aβ40 and Aβ42. MOAB-2 did not co-localize with either N- or C-terminal antibodies to APP. In addition, no MOAB-2-immunreactivity was observed in the brains of 5xFAD/BACE-/- mice, although significant amounts of APP were detected by N- and C-terminal antibodies to APP, as well as by 6E10. In both 5xFAD and 3xTg mouse brain tissue, MOAB-2 co-localized with cathepsin-D, a marker for acidic organelles, further evidence for intraneuronal Aβ, distinct from Aβ associated with the cell membrane. MOAB-2 demonstrated strong intraneuronal and extra-cellular immunoreactivity in 5xFAD and 3xTg mouse brain tissues.

Biosensis now offers biotinylated MOAB-2 antibody allowing more flexibility in experimental design by using the biotin-avidin/streptavidin detection method. Biotinylated MOAB-2 antibody may also help to reduce background staining in difficult-to-stain tissues and increase detection sensitivity. The ability of biotinylated MOAB-2 antibody to detect amyloid beta has been validated by IHC.

The spectrin family of proteins were originally discovered as major components of the submembraneous cytoskeleton of osmotically lysed red blood cells (1). The lysed blood cells could be seen as clear red blood cell shaped objects in the light microscope and were referred to as red cell "ghosts". The major proteins of these ghosts proved to be actin, ankyrin, band 4.1 and several other proteins, including two major bands running at about 240kDa and 260kDa on SDS-PAGE gels. This pair of bands was named "spectrin" since they were discovered in these red blood cell ghosts (1). Later work showed that similar high molecular bands were seen in membrane preparations from other eukaryotic cell types. Work by Levine and Willard described a pair of about ~240-260kDa molecular weight bands which were transported at the slowest rate along mammalian axons (2). They named these proteins "fodrin" as antibody studies showed that they were localized in the sheath under the axonal membrane, but not in the core of the axon (2; fodros is Greek for sheath). Subsequently fodrin was found to be a member of the spectrin family of proteins, and the spectrin nomenclature is now normally used (3). Spectrins form tetramers of two alpha and two beta subunits, with the alpha corresponding to the lower molecular weight ~240kDa band and the beta corresponding to the ~260kDa or in some case much larger band. Most spectrin tetramers are about 0.2microns or 200nm long, and each alpha and beta subunit has a cell type specific expression pattern. The basic structure of each spectrin subunit is the spectrin repeat, which is a sequence of about 110 amino acids which defines a compact domain contain three closely packed alpha-helices. Each spectrin subunit contains multiple copies of this repeat, with 20 in each of the alpha subunits. The beta I-IV subunits each contain 17 spectrin repeats, while the beta V subunit, also known as beta-heavy spectrin, contains 30 of these repeats. The various subunits also contain several other kinds of functional domain, allowing the spectrin tetramer to interact with a variety of protein, ionic and lipid targets. The alpha-subunits each contain one calmodulin like calcium binding region and one Src-homology 3 (SH3) domain, an abundant domain involved in specific protein-protein interactions. The beta subunits all have a N-terminal actin binding domain and may also have one SH3 domain and one pleckstrin homology domain, a multifunctional type of binding domain which in beta I spectrin at least binds the membrane lipid PIP2 (5). Spectrins are believed to have a function in giving mechanical strength to the plasma membrane since the tetramers associate with each other to form a dense submembraneous geodesic meshwork (3). They also bind a variety of other membrane proteins and membrane lipids, and the proteins they bind to are therefore themselves localized in the membrane. Diseases may be associated with defects in one or other of the spectrin subunits (6). For example, some forms of hereditary spherocytosis, the presence of spherical red blood cells which are prone to lysis, can be traced to mutations in some of the spectrin subunits (7). The alpha-II subunit is widely expressed in tissues but, in the nervous system, is found predominantly in neurons. The antibody can therefore be used to identify neurons and fragments derived from neuronal membranes in cells in tissue culture and in sectioned material.

Mouse NGF (2.5S) was isolated from mouse submaxillary glands by method of Mobley et al (1976) and is a form of beta-NGF that has identical biological properties. NGF is known to regulate the survival and development of certain sympathetic and sensory neurons. It is a dimer with 2 identical polypeptide chains and dimeric molecular weight of approximately 26,500 Da. Isolation and purification of NGF from mouse submaxillary glands yields preparations of NGF (2.5S) with identical biological activity but with cleavages at the amino terminus (with the loss of 8 amino acids) and/or at the carboxy-terminus (with the loss of arginine). These preparations are named 2.5 NGF.

FUNCTION: Functions within a multiprotein E3 ubiquitin ligase complex, catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. These substrates include SYT11, CCNE1, GPR37, STUB1, a 22 kDa O-linked glycosylated isoform of SNCAIP and SEPT5. May play a more general role in the ubiquitin proteasomal pathway by participating in the removal and/or detoxification of abnormally folded or damaged protein. Loss of this ubiquitin ligase activity appears to be the mechanism underlying pathogenesis of PARK2. May protect neurons against alpha synuclein toxicity, proteasomal dysfunction, GPR37 accumulation, and kainate-induced excitotoxicity. May play a role in controlling neurotransmitter trafficking at the presynaptic terminal and in calcium-dependent exocytosis. Regulates cyclin E during neuronal apoptosis. May represent a tumor suppressor gene. SUBCELLULAR LOCATION: Cytoplasm. Co-localizes with STY11 in neutrites. Co-localizes with SNCAIP in brainstem Lewy bodies. TISSUE SPECIFICITY: Highly expressed in the brain including the substantia nigra. Expressed in heart, testis and skeletal muscle. Expression is down-regulated or absent in tumor biopsies, and absent in the brain of PARK2 patients. Overexpression protects dopamine neurons from kainate-mediated apoptosis.

The 6X His tag is a short peptide sequence of 6 histidine residues. Epitopes such as the 6X His tag are often included with the target DNA at the time of cloning to produce fusion proteins containing the tag sequence. This allows anti-epitope tag antibodies such as this one to serve as a universal detection reagent for any recombinant protein containing this tag. Anti-epitope antibodies are a useful alternative to generating antibodies to identify a specific recombinant protein. The 6X His motif is often used as a tag on recombinant proteins to facilitate purification with immobilized metal-affinity chromatography.
