Anti-Tyrosine Hydroxylase pS40 antibody is suitable for use in ELISA, Western Blotting, IHC and IF. Specific conditions for reactivity should be optimized by the end user. Expect a band of approximately 42/44 kDa in size corresponding to the tyrosine hydroxylase proteins phosphorylated at Ser40 in the appropriate cell lysate or extract. Some higher molecular weight bands may be detected by the antibody depending upon the brain region being studied, protein loads and the detection methods used. The antibody has three orders of magnitude selectivity over dephospho TH.
