The original antibody was generated by immunizing mice intramuscularly with purified peptide GGDLLTYLRKARMATFYGPLLTLVDLVDLCVDISKGCVYLERMHFIHRDLAARNCLVSVKDYTSPRIVKIGDFGLARDIYKNDYYRKRGEGLLPVRWMAPESLMDGIFTTQSDVWSFGIL and immune enhancer PEI in a ratio of 1:3 and dissolved in a serum free and dual-antibody-free DMEM solution. The purified peptide is identified as a specific binding fragment of PF-06463922 (Crizotinib, Xalkori).
