This affinity purified 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 band approximately 50 kDa in size corresponding to Mer2 protein by western blotting in the appropriate cell lysate or extract. This antibody is reactive with both phosphorylated and unphosphorylated Mer2 at the S30 position.
