PDGFRβ Kinase Enzyme System

The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The PDGFRβ Kinase Enzyme System contains:

• PDGFRβ Kinase, 10μg (Human, recombinant; amino acids 557–end). MW: ~104kDa.
• Poly (4:1 Glu, Tyr) Peptide Substrate.
• Reaction Buffer, DTT.

Recombinant human PDGFRβ (amino acids 557–end) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. PDGFRβ (platelet-derived growth factor receptor β) is a member of the PDGFR family of membrane receptors with intrinsic tyrosine kinase activity. PDGFRβ-deficient mice are hemorrhagic, severely anemic and exhibit a defect in kidney glomeruli function. However, absence of PDGFRβ has no impact on major blood vessels and the heart. PDGFRβ expression and activity is elevated in several cancers, and inhibition of PDGFRβ activity blocks progression of renal carcinoma in an animal model.

The PDGFRβ Kinase Enzyme System can be purchased with or without the ADP-Glo™ Kinase Assay reagents. Used together, the ADP-Glo™ Kinase Assay + Kinase Enzyme Systems provide a convenient method for profiling the effect of lead compounds on kinase activity. Assay advantages include broad dynamic range, ease of use and high sensitivity. Kinase Enzyme Systems are manufactured by SignalChem. Bulk quantities available upon request.

Use with ADP-Glo™ Kinase Assay

The ADP-Glo™ Kinase Assay is a luminescent kinase assay that measures ADP formed from a kinase reaction; ADP is converted into ATP, which is a substrate in a reaction catalyzed by Ultra-Glo™ Luciferase that produces light. The luminescent signal positively correlates with ADP amount and kinase activity. The assay is well suited for measuring the effects of chemical compounds on the activity of a broad range of purified kinases, making it ideal for both primary screening as well as kinase selectivity profiling. The ADP-Glo™ Kinase Assay can be used to monitor the activity of virtually any ADP-generating enzyme (e.g., kinase or ATPase) using up to 1mM ATP.
