Anti-GAB1 pY656 Antibody has been tested for use in ELISA and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a predominant band at 76.6 kDa by western blotting in the appropriate cell lysate or extract. This phospho-specific polyclonal antibody reacts with human GAB1 pY659 and shows minimal reactivity by ELISA against the non-phosphorylated form of the immunizing peptide.
