Western blot analysis from lysates of a CHO cell line transfected with human IL-23. A PVDF membrane was probed with 1 µg/mL of Goat Anti-human IL-23 p19 Antigen Affinity-purified Polyclonal Antibody (Product # PA5-46913) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody. A specific band was detected for IL-23 p19 at approximately 21 kDa (as indicated). This experiment was conducted under reducing conditions.
