Among the water-based polymers developed to address environmental issues and the increasing use of water-based products due to VOC regulations and desolventing, the EPOCROSTM is a reactive polymer with an oxazoline group on the side chain and is used as a cross-linking agent for water-based resins. Among the water-based polymers developed to address environmental issues and the increasing use of water-based products due to VOC regulations and desolventing, the EPOCROSTM WS series is a “water-soluble type” with the following structure.Features and PropertiesHigher reactivity than water-based epoxy, melamine, blocked isocyanateVOC free (EPOCROS™ WS-300 and EPOCROS™ WS-700)High crosslinking density with a small amount addedOne-pack type with long usage timeImproves water resistance, solvent resistance, heat resistance, and the strength of films, etc.Adhesion-imparting possible to PET, OPP, PVC, etc.Fast dryingLow toxicity (Ames Test: Negative, Primary Skin Irritation Test: No irritation)WS Series Product LineupApplicationsNonwoven fabric bindersPigment printingCoatings (metals, films, leather)Paint and coatings, Primers (plastics, building materials, vehicles)AdhesivesMethodASSAY for Product Code DILW:One unit equals a decrease in absorbance of 1.0 per minute at 25°C at pH 7.5 with 2,6-dichlorophenolindophenol as the chromogen.Reagents0.2 M Tris⋅HCl buffer, pH 7.50.006 M NADH.

Description: Major histocompatibility complex, class II, DR alpha (HLA-DRA) belongs to the MHC class II family. HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) Purity: >90%, by SDS-PAGE visualized with Coomassie® Blue Staining. Description: Major histocompatibility complex, class II, DR alpha (HLA-DRA) belongs to the MHC class II family. HLA-DRA binds peptides derived from antigens which access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for identification by the CD4 T-cells. The peptide binding cleft accommodates peptides of 10-30 residues. The peptides presented by MHC class II molecules are generated mainly by degradation of proteins which access the endocytic route, where they are processed by lysosomal proteases and other hydrolases...

The PEDF is a Purity＞97% by SDS-PAGE and HPLC analyses.FunctionPigment epithelium-derived factor (PEDF) is encoded by the SERPINF1 gene in humans and found in verebrates. It is a secreted phosphoglycoprotein that belongs to the clade F subfamily, serpin superfamily of proteinase inhibitors. The PEDF is a noninhibitory serpin with neurotrophic, anti-angiogenic, and anti-tumorigenic properties. It is synthesized as a 418 a.a. about 50kDa precursor that contains a 19 a.a. signal sequence and a 399 a.a. mature region that shows a pyroglutamate at Gln20. Like other serpins, it contains three β-sheets, 810 α-helices, and a C-terminal RCL (reactive center loop). Unlike other serpins with Ser protease inhibiting activity. PEDF has functions of inducing extensive neuronal differentiation in retinoblastoma cells, inhibiting of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. PEDF is researched as a therapeutic candidate for treatment of such conditions as choroidal neovascularization, heart disease, and cancer... Read More |
