| Description | Cholecystokinin Octapeptide, desulfated TFA is a synthetic desulfated octapeptides of Cholecystokinin (CCK) | description：Bovine pancreatic deoxyribonuclease I produced recombinantly in yeast, Pichia pastoris, to decrease levels of contaminating RNase and eliminate potential pathogens associated with animal based materials.Bovine pancreas is a rich source of RNase A which is often found in many description：Bovine pancreatic deoxyribonuclease I produced recombinantly in yeast, Pichia pastoris, to decrease levels of contaminating RNase and eliminate potential pathogens associated with animal based materials.Bovine pancreas is a rich source of RNase A which is often found in many commercial DNase preparations. Producing DNase I by recombinant means in an organism with much lower levels of endogenous RNase greatly facilitates purification of an enzyme with undetectable levels of RNase. The processes involved in the production and isolation of recombinant DNase I are completely devoid of animal based components which eliminates the possibility of introducing animal derived pathogens into bioprocessing procedures.Animal Free/AF. Recombinant Bovine pancreatic deoxyribonuclease 1 produced in Pichia pastoris. Chromatographically purified. Free of animal derived components, RNases & proteases.

Description： CD4, also known as L3T4, T4, and W3/25, is an approximately 55 kDa type I transmembrane glycoprotein that is expressed predominantly on thymocytes and a subset of mature T lymphocytes. It is a standard Purity: >95%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description： CD4, also known as L3T4, T4, and W3/25, is an approximately 55 kDa type I transmembrane glycoprotein that is expressed predominantly on thymocytes and a subset of mature T lymphocytes. It is a standard phenotype marker for the identification of T cell populations. Mature human CD4 consists of a 371 amino acid (aa) extracellular region containing four immunoglobulin-like domains, a 22 aa transmembrane segment, and a 40 aa cytoplasmic domain. Within the ECD, human CD4 shares approximately 52% aa sequence identity with mouse and rat CD4. CD4 is expressed along with CD8 on double positive T cells during their development in the thymus. Either CD4 or CD8 expression is then lost, giving rise to single positive (SP) CD4+ or CD8+ mature T cells. CD4+ SP cells, also known as T helper cells, further differentiate into multiple subsets of CD4+ cells including Th1, Th2, Th17, Tfh, and Treg cells which regulate humoral and cellular immunity. CD4 is reexpressed on circulating CD8+ T cells upon activation and contributes to their cytotoxic effector activity. In human, CD4 is additionally expressed on macrophages, neutrophils, monocytes, NK cells, and neurons and glial cells in the brain. Similar CD4 distribution between species cannot be assumed as demonstrated by its presence on macrophages in human and rat but not in mouse. CD4 binds directly to MHC class II molecules on antigen presenting cells. This interaction contributes to the formation of the immunological synapse which is focused around the TCR-MHC class II-antigenic peptide interaction. Palmitoylation of two cysteine residues in the cytoplasmic tail of CD4 promotes the localization of CD4 in lipid rafts and its ability to augment TCR signaling via activation of the tyrosine kinase Lck. CD4 also functions as a chemotactic receptor for IL-16 and, in human, as a co-receptor for the gp120 surface glycoprotein of HIV-1...

The extracellular region can be proteolytically shed from the cell surface. Mature human NG2 consists of a 2195 amino acid (aa) extracellular domain (ECD), a 21 aa transmembrane segment, and a 77 aa cytoplasmic domain. Within aa 1583-2224, human NG2/CSPG4 shares 83% aa sequence identity with mouse and rat CSPG4. NG2 binds to the extracellular matrix proteins Laminin, Tenascin, and Collagens II, V, and VI as well as to the growth factors FGF-2 and PDGF-AA. NG2 is expressed on glial cell progenitors known as O2A cells or NG2 glia. These cells are neuronally responsive and differentiate primarily into oligodendrocytes but also into astrocytes. NG2 associates with PDGF R alpha and the AMPA R subunit GluR2. It is up-regulated on microglial cells during inflammation and contributes to the induction of inflammatory mediators. Various CSPGs in the brain inhibit neurite outgrowth through interactions with Nogo Receptor/NgR1 and NgR3. This recombinant protein product corresponds to the last 5 CSPG repeats, a region which can independently inhibit neurite outgrowth. NG2 is also expressed on vascular mural cells and capillaries. It promotes vascular endothelial cell (EC) migration and angiogenesis through interactions with Galectin-3 and Integrin alpha 3 beta 1 on EC, Plasminogen, and Angiostatin. NG2 is also expressed on a variety of tumors where it contributes to tumor cell adhesion, motility, and invasion... Read More |
