Scientific Data Images for Human 14‑3‑3 zeta Antibody

Detection of Human, Mouse, and Rat 14‑3‑3 zeta by Western Blot.

Western blot shows lysates of SH-SY5Y human neuroblastoma cell line, SK-Mel-28 human malignant melanoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and C6 rat glioma cell line. PVDF membrane was probed with 0.2 µg/mL of Mouse Anti-Human 14-3-3 zeta Monoclonal Antibody (Catalog # MAB2669) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for 14-3-3 zeta at approximately 27 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

14‑3‑3 zeta in Human Squamous Cell Carcinoma.

14-3-3 zeta was detected in immersion fixed paraffin-embedded sections of human squamous cell carcinoma using Mouse Anti-Human 14-3-3 zeta Monoclonal Antibody (Catalog # MAB2669) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue). Specific staining was localized to nuclei and plasma membrane. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Detection of Human 14‑3‑3 zeta by Simple Western^TM.

Simple Western lane view shows lysates of SH‑SY5Y human neuroblastoma cell line, loaded at 0.5 mg/mL. A specific band was detected for 14‑3‑3 zeta at approximately 34 kDa (as indicated) using 2 µg/mL of Mouse Anti-Human 14‑3‑3 zeta Monoclonal Antibody (Catalog # MAB2669). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: 14-3-3 zeta

14-3-3 proteins are a highly conserved family of homo- and heterodimeric phosphoserine/threonine-binding proteins present in high abundance in all eukaryotic cells. 14-3-3 proteins were the first polypeptides shown to have pSer/Thr binding properties, generally recognizing the consensus sequences RSXpSXP and RXY/FXpSXP (where X is any amino acid). 14-3-3 proteins act as key regulators of intracellular signal transduction through their ability to bind specific motifs phosphorylated on serine or threonine. For example, the binding of 14-3-3 to phosphorylated BAD blocks its proapoptotic association with Bcl-XL. There are at least seven distinct 14-3-3 genes in vertebrates, alpha/beta, epsilon, eta, gamma, theta, sigma and zeta ( alpha/ beta, epsilon, eta, gamma, tau/ theta, sigma, and zeta/ delta). 14-3-3 zeta, also known as Tyrosine 3-Monooxygenase/Tryptophan 5-Monooxygenase Activation Protein, zeta isoform (gene name YWHAZ) is a 245 amino acid, 27 kDa protein.
