Use of dextrans as long and hydrophilic spacer arms improves the performance of immobilized proteins acting on macromolecules. Dextrans are used in many applications as platelet aggregants, plasma volume extenders, osmotic pressure regulators, stabilizers, organ separation media, matrix components, copolymers, microcarriers, binding agents, viscosity modifiers, antithrombotics, lubricants and physical structure components. They may be used as long hydrophilic spacer arms to improve the performance (freedom of movement) of conjugated/bound proteins. Dextrans may be derivatized for use in biosensor systems.
Dextran is branched polysaccharide made up of linear α (1→6) linked glucose units and α (1→3) link initiated branches; it ranges in size from 10,000 to 150,000 Kd.Depending upon its molecular weight it has different uses in different fields.
Physical Appearance: White powder

CTSK(cathepsin K), also named as CTSO, CTSO2, is a recently identified lysosomal cysteine proteinase. CTSK is synthesized as a proenzyme of 38 kDa and subsequently enters acidic lysosomal compartments, in which the propeptide is cleaved and transformed into an active enzyme and it may influence adipocyte differentiation through modifying extracellular matrix components. It is revealed both the 46-kDa cathepsin-K precursor and the 30-kDa mature form in mouse bone extracts. The high CTSK protein levels are only detected in primary cultured fibroblasts derived from normal and neoplastic breast tissue, where the 37- and 25-kDa bands to be detected correspond to pro- and mature proteins through western blot. The full length protein has a signal peptides with 15 amino acids and a propeptide with 99 amino acids. CTSK may have cross reaction with the other members of cathepsin family and form a complex of 70 kDa with an unidentified subunit.

CELLvo™ Healthy Human Chondrocytes (50-70y) are primary, uncultured cells isolated from recently-diseased cadaver cartilage from donors between 50 and 70 years old. Healthy status is determined by macroscopic inspection of the tissue using a modified outerbridge (1960) scale in order to distinguish healthy joints from those with signs of osteoarthritis. Cells are isolated by enzymatic digestion prior to cryopreservation.

Apoptosis is related to many diseases and development. Members in the Bcl-2 family are critical regulators of apoptosis by either inhibiting or promoting cell death. Bcl-2 homology 3 (BH3) domain is a potent death domain. BH3-only proteins, including Bad, Bid, Bik, Hrk, Bim, Noxa, and PUMA, form a growing subclass of the Bcl-2 family. A novel BH3-only protein was recently identified in human and mouse and designated Bmf (for Bcl-2-modifing factor). The BH3 domain in Bmf is required both for binding to Bcl-2 proteins and for triggering apoptosis. In healthy cells, Bmf associates with the dynein light chain 2 (DLC2) component of the myosin V motors and is sequestered by the cell's actin cytoskeleton. Disruption of the actin cytoskeleton, either by depolymerization of actin filaments or by detachment of cells from the extracellular matrix, triggers release and activation of Bmf, initiating the downstream apoptotic program. Bmf is constitutively expressed in many tissues.

Chromatin, the physiological packaging structure of histone proteins and DNA, is considered a key element in regulating gene expression. Several complexes involved in transcriptional regulation function by either modifying histones or altering chromatin structure. Postranslational modifications of histones, such as acetylation, phosphorylation and methylation, contribute to the regulation of transcription. The ATP-dependent chromatin-remodeling complexes alter chromatin structure by using the energy of ATP hydrolysis to locally disrupt the association of histones with DNA, displacing the nucleosomes from promoter and enhancer regions, and therefore allowing transcription initiation. Chromatin remodeling complexes have been purified from a variety of organisms, and most cell types contain more than one type of complex. These complexes contain structurally related catalytic subunits, but differ in the way in which they manipulate chromatin. Three families of complexes have been described the SWI/SNF family, ISWI family, and Mi-2 family. The SWI/SNF family of ATP-dependent remodeling complexes was identified in yeast, drosophila, and human. It causes nucleosomes to change structure and/or position in order to allow transcriptional activators to gain access to their target sites. The SWI/SNF complex was originally identified in yeast as a 2 MDa complex, later shown to be highly conserved in all eukaryotes. Components of the hSWI/SNF complexes have been implicated in a range of cellular events including gene activation, regulation of cell growth, and development. The human homologue of yeast SNF5, SMARCB1, was identified in a two-hybrid screening performed to identify binding targets of the integrase of HIV, and the gene called INI1. Many studies have indicated that yeast SNF and its human counterparts are able to interact with sequence-specific transcription factors, which may recruit the complex to specific genes. For example, it has been shown that SMARCB1 interacts with the protooncogene c-Myc and the SWI complex is necessary for c-Myc mediated transactivation. Mutations in SNF5 and Brg1, both SWI components, suggest a connection of the complex with cancer. In fact, SMARCB1 displays properties of a tumor-suppressor gene, as sporadic rhabdoid tumors show biallelic loss-of-function mutations, and germline mutations confer and autosomal-dominant syndrome that predisposes patients to a variety of rhabdoid cancers.

Dextran is a high molecular weight polymer of anhydroglucose. It is composed of approximately 95% alpha-D-(1-->6) linkages. The remaining a(1-->3) linkages account for the branching of dextran.
Dextrans are used in many applications as volume extenders, stabilizers, matrix components, binding platforms, lubricants and physical structure components.
