Anti-Lck (phospho Y416) + FYN (phospho Y416) Antibody

This rabbit polyclonal IgG from Antibodies.com recognizes the activating autophosphorylation site shared by Lck and FYN, two Src-family tyrosine kinases that initiate T-cell receptor signaling. Supplied unconjugated at 50 µl, the reagent is validated for western blot and immunoprecipitation workflows on human samples and is widely used to monitor kinase activation dynamics in immune cell lysates following TCR stimulation.

Because the antibody is unconjugated, it pairs cleanly with user-selected secondary reagents for chemiluminescent, fluorescent, or affinity-tag detection, and supports pull-down of active Src-family kinase complexes for downstream in vitro kinase assays or mass spectrometry interactome studies. Store frozen at -20°C in working aliquots; avoid repeated freeze-thaw cycles to preserve phospho-specific binding.
