title: [Cloning, expression and purification of KDR tyrosine kinase].
abstract: The catalytic domain of KDR kinase (KDR-CD) was amplified from RNA of HUVCEs cells with RT-PCR and expressed in E. coli BL21(DE3) by plasmid pET30a as vector. The recombinant protein was purified with affinity chromatography (Ni-NTA). Western blotting showed that the recombinant KDR-CD was phosphorylated in E. coli BL21(DE3). The recombinant KDR-CD was identified to have kinase activity catalyzing the substrate phosphorylated with ATP in the enzymatic reaction.
