ARG52324 anti-HDAC2 phospho (Ser394) antibody WB image Western Blot: mouse heart lysate showing specific immunolabeling of the ~55k HDAC2 protein phosphorylated at Ser 394 (control) stained with ARG52324 HDAC2 (phospho Ser394) antibody. Phosphospecificity is shown in the second lane (lambda-phosphatase: λ-Ptase). The blot is identical to the control except that the lysate was incubated in λ-Ptase (800 units/1mg protein for 30 min). The immunolabeling is completely eliminated by treatment with λ-Ptase.
