Western blot shows lysates of MCF‑7 human breast cancer cell line, U937 human histiocytic lymphoma cell line, and A431 human epithelial carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Human SRPK2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5530) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SRPK2 at approximately 115 to 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
