Supplier: ENZO LIFE SCIENCES

The octapeptide circulatory hormone Angiotensin II is a critical regulator of cardiovascular homeostasis formed in blood, with dual function in tissues of the brain, kidney, heart, and vasculature as an autocrine/paracrine growth hormone. The actions of angiotensin II are mediated by type one (AT1) and type two (AT2) angiotensin II receptors, members of the seven-transmembrane Gprotein coupled receptor (GPCR) family. AT1 receptors couple predominantly with Gq/11 alpha subunits, and signal through phospholipases C, D, and A2, inositol phosphates, and calcium channels, as well as a variety of serine/threonine and tyrosine kinases. AT1 expression is greatest in vascular smooth muscle, liver, kidney, adrenal cortex, brain, and lung, and is primarily responsible for the physiological effects of angiotensin II, including regulation of arterial blood pressure, electrolyte and water balance, thirst, hormone secretion, and renal function. The AT2 receptor displays approximately 30% identity to the AT1 receptor, and is highly expressed during embryonic development. AT2 expression in adult tissue is limited to the adrenal medulla, brain, and reproductive tissues, but is upregulated in injured tissue following myocardial infarction, vascular injury, and wound healing. AT2 receptor signaling is not dependent on G-protein coupling or receptor phosphorylation, although coupling to Gia2 and Gia3 alpha subunits occurs in some tissues. AT2 activation can stimulate tyrosine and serine/threonine phosphatases through activation of nitric oxide and cGMP, and appears to counteract the stimulatory effects of AT1 receptor and growth factor receptor signaling.

Supplier: Thermo Fisher Scientific

Thermo Scientific Pierce SMCC is a hetero-bifunctional crosslinker that contain N-hydroxysuccinimide (NHS) ester and maleimide groups that allow covalent conjugation of amine- and sulfhydryl-containing molecules. NHS esters react with primary amines at pH 7–9 to form amide bonds, while maleimides react with sulfhydryl groups at pH 6.5–7.5 to form stable thioether bonds. In aqueous solutions, NHS ester hydrolytic degradation is a competing reaction whose rate increases with pH. The maleimide group is more stable than the NHS-ester group, but will slowly hydrolyze and lose its reaction specificity for sulfhydryls at pH values > 7.5. For these reasons, conjugations with these crosslinkers are usually performed at pH 7.2–7.5, with the NHS ester (amine-targeted) reacted before or simultaneous with the maleimide (sulfhydryl-targeted) reaction.

Hemagglutinin Monoclonal Antibody: Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA. Novel influenza virus strains caused by genetic drift and viral recombination emerge periodically to which humans have little or no immunity, resulting in devastating pandemics. Influenza A can exist in a variety of animals, but it is in birds that all subtypes can be found. These subtypes are classified based on the combination of the virus coat glycoproteins hemagglutinin (HA) and neuraminidase (NA) subtypes. HA interacts with host cell surface proteins containing oligosaccharides with terminal sialyl residues. Its extracellular region has two domains (HA1 and HA2); HA1 is cleaved from the main hemagglutinin protein by the host immune system. During 1997, an H5N1 avian influenza virus was determined to be the cause of death in 6 of 18 infected patients in Hong Kong. This more recent virulent strain of H5N1 is now seen in Africa and Europe, as well as in Southeast Asia. There is some evidence of human to human spread of this virus, but it is thought that the efficiency of this type of transmission is low. Virus isolated from a human infected with the H5N1 strain in 1997 could bind to oligosaccharides from human as well as avian sources, indicating its species-jumping ability.

Supplier: Biosensis

FUNCTION: Promotes microtubule assembly and stability, and might be involved in the establishment and maintenance of neuronal polarity. The C-terminus binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that tau functions as a linker protein between both. Axonal polarity is predetermined by tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization.  SUBCELLULAR LOCATION: Cytoplasm; cytosol. Cell membrane. Mostly found in the axons of neurons, in the cytosol and in association with plasma membrane components. ALTERNATIVE PRODUCTS: 8 named isoforms produced by alternative splicing. Additional isoforms seem to exist. Isoforms differ from each other by the presence or absence of up to 5 of the 15 exons. One of these optional exons contains the additional tau/MAP repeat. TISSUE SPECIFICITY: Expressed in neurons. Isoform PNS-tau is expressed in the peripheral nervous system while the others are expressed in the central nervous system. DEVELOPMENTAL STAGE: Four-repeat (type II) tau is expressed in an adult-specific manner and is not found in fetal brain, whereas three-repeat (type I) tau is found in both adult and fetal brain. DOMAIN: The tau/MAP repeat binds to tubulin. In Alzheimer disease, the neuronal cytoskeleton in the brain is progressively disrupted and replaced by tangles of paired helical filaments  and straight filaments, mainly composed of hyperphosphorylated forms of Microtubule-associated protein Tau. Defects in Microtubule-associated protein Tau are a cause of frontotemporal dementia and parkinsonism linked to chromosome 17, as well as a number of other neurodegenerative diseases.
