Purity ~90% determined by HPLC and mass spectroscopy. Synthetic linear peptide (EAIYAAPFAKKK)(K); substrate for Abl kinase. Abl Protein Tyrosine Kinase (AbI) is a truncated form of the v-AbI Protein Tyrosine Kinase, a partner in the Gag-Abl fusion protein of the Abelson murine leukemia virus. Abl contains 407 amino acids (residues 237-643 of the p120-gag-abl polyprotein) which include the kinase catalytic domain, SH2 domain on the N-terminus and the I237M mutation. Abl is identical to the normal c-Abl. Abl is autophosphorylated on tyrosine(s). Applications: Suitable for use in Kinase assay.
