Detection of Human/Mouse/ Rat 14‑3‑3 sigma by Western Blot.
Western blot shows lysates of A431 human epithelial carcinoma cell line and mouse brain tissue. PVDF membrane was probed with 1 µg/mL Goat Anti-Human/ Mouse/Rat 14‑3‑3 sigma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4424) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). 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 sigma was detected at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: 14-3-3 sigma
14-3-3 proteins are a highly conserved family of homo- and heterodimeric phosphoserine/threonine-binding proteins present in all eukaryotic cells. 14-3-3 proteins act as key regulators of intracellular signal transduction through their ability to bind specific motifs phosphorylated on serine or threonine. There are at least 7 distinct mammalian 14-3-3 genes: alpha / beta, epsilon, eta, gamma, tau / theta, sigma, and zeta /δ.
