recombinant protein kinases for your assays
Protein phosphorylation is a common event in cell signaling pathways. Kinases are enzymes that add a phosphate group to proteins and are classified by the residue that accepts the phosphate (Ser/Thr or Tyr). Kinases that phosphorylate serine or threonine residues are more prevalent than tyrosine kinases. Active Motif offers highly purified, active kinases for use in cell signaling kinase assays.
