Western blot shows lysates of Raji human Burkitt's lymphoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 1 µg/mL Goat Anti-Human/Mouse/Rat 14‑3‑3 theta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4425) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). For additional reference, recombinant human 14-3-3 beta, epsilon, eta, gamma, sigma, theta, and zeta (2 ng/lane) were included. A specific band for 14‑3‑3 theta was detected at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
