Specification

• Species: Human
• Source: CHO
• Tag: Avi&Fc
• Protein Length: Leu33-Lys531
• Description: PDGF is a major serum mitogen that can exist as a homo or hetero-dimeric protein consisting of disulfide-linked PDGF-A and PDGF-B chains. The PDGF-AA, PDGF-BB and PDGF-AB isoforms have been shown to bind to two distinct cell surface PDGF receptors with different affinities. Where as PDGF R alpha binds all three PDGF isoforms with high affinity, PDGF R beta binds PDGF-BB only with high-affinity. Both PDGF R alpha and PDGF R beta are members of the class III subfamily of receptor tyrosine kinases (RTK) that also includes the receptors for M-CSF, SCF and Flt3 ligand. All class III RTKs are characterized by the presence of five immunoglobulin-like domains in their extracellular region and a split kinase domain in their intracellular region. PDGF binding induces receptor homo-and hetero-dimerization and signal transduction. The expression of the alpha and beta receptors is independently regulated in various cell types. Recombinant soluble PDGF R beta binds PDGF with high affinity and is potent PDGF antagonist. Our Avi-tag Biotinylated Human PDGF R beta features biotinylation at a single site contained within the Avi-tag, a unique 15 amino acid peptide. Protein orientation will be uniform when bound to streptavidin-coated surface due to the precise control of biotinylation and the rest of the protein is unchanged so there is no interference in the protein's bioactivity
• Predicted N Terminal: Leu33
• Form: Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
• Bio-activity: Measured by its binding ability in a functional ELISA. When Recombinant Human PDGFBB is coated at 1 μg/mL (100 μL/well), Biotinylated Recombinant Human PDGFRB Fc Chimera Avi-tag binds with an ED50 of 12-120 ng/mL. Measured by its ability to inhibit the biological activity of PDGF-BB using NR6R‑3T3 mouse fibroblast cells. The ED50 for this effect is 1-3 µg/mL.
