The lectin has a molecular weight of 110 kDa and consists of four identical subunits of approximately 27 kDa each. PNA is a carbohydrate-free protein that displays specificity towards ?-D-Gal(1-3)-D-galNAc. It has potent anti-T activity and can be used to distinguish between human lymphocyte subsets. PNA has been used in tumour tissue determination for transitional mucosa malignancies. The lectin also agglutinates neuraminidase-treated human erythrocytes at < 0.1 µg/ml after trypsin treatment of cells and its activity is inhibited by lactose and galactose. PNA lectin is provided as a white to light yellow lyophilized powder from a buffer containing 10 mM NH4HCO3. The purity is determined by SDS-PAGE, which generates one band at 25-27 kDa.● Ultrapure quality ● Strong anti-T activity ● Sugar specificity: ?-D-Gal-(1-3)-D-GalNAc ● Agglutinates rabbit erythrocytes at < 0.1 µg/ml after trypsin treatment of the cells ● Lyophilized powderProbe in histochemistry and immuno-histochemistry;Human erythrocyte/lymphocyte studies...

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...

It plays a critical role in inflammation by Background:VCAM-1, also known as CD106, is an immunoglobulin (Ig)-like adhesion molecule that is mainly expressed in endothelial cells and other cell types including macrophages, dendritic cells, neurons, smooth muscle cells, fibroblasts, and oocytes. It plays a critical role in inflammation by recruiting leukocytes to acute and chronic inflammation sites. Alternatively-spliced forms are known to occur, but the most common form is a type I transmembrane protein with a 674 aa extracellular domain (ECD) that includes seven C2-type immunoglobulin domains, a 22 aa transmembrane segment, and a 19 amino acid (aa) cytoplasmic tail. Within the ECD, human VCAM-1 shares 75% and 76% aa sequence identity with the mouse and rat VCAM-1, respectively. VCAM-1 binds to leukocyte integrins alpha 4 beta 1 (VLA-4) and alpha 4 beta 7. During the inflammatory adhesion mechanism, activated integrins halt rolling leukocytes and attach them firmly to the vascular endothelium. The VCAM-1:VLA-4/ alpha 4 beta 7 interaction is also thought to be involved in the extravasation of white blood cells through the blood vessel wall to sites of inflammation. ELISA techniques have shown that detectable levels of soluble VCAM-1 are present in the biological fluids of apparently normal individuals, but elevated levels of serum VCAM-1 are indicative of future Atrial Fibrillation incident as well as liver disease. Tumor cells use overexpression of VCAM-1 as means of escaping immune surveillance.Post-translational modifications:Sialoglycoprotein.Function:Important in cell-cell recognition. Appears to function in leukocyte-endothelial cell adhesion. Interacts with the beta-1 integrin VLA4 on leukocytes, and mediates both adhesion and signal transduction. The VCAM1/VLA4 interaction may play a pathophysiologic role both in immune responses and in leukocyte emigration to sites of inflammation... Read More |
