Experimental details

Detection of Rat and Human Phospho-MKK4 (S257/T261) by Western Blot. Western blot shows lysates of PC-12 rat adrenal pheochromocytoma cell line untreated (-) or treated (+) with 300 mM sorbitol for 30 minutes and HepG2 human hepatocellular carcinoma cell line untreated or treated with 10 ng/mL Recombinant Human IL-1 beta (Catalog # 201-LB) for 20 minutes. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human/Mouse/Rat Phospho-MKK4 (S257/T261) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2990), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-MKK4 (S257/T261) at approximately 44 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
