STAT5b Antibody (1032E) [Unconjugated]

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, Daudi human Burkitt's lymphoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, M1 mouse myeloid leukemia cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for STAT5b at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

STAT5b was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; NL004) and counterstained with DAPI (blue). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Simple Western lane view shows lysates of M1 mouse myeloid leukemia cell line and Daudi human Burkitt's lymphoma cell line, loaded at 0.2 mg/mL. A specific band was detected for STAT5b at approximately 90 kDa (as indicated) using 1 μg/mL of Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

STAT5b was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line treated with IFN-alpha 1 but is not detected in STAT5b knockout (KO) HeLa cell line using Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line, STAT1 knockout (KO) HeLa cell line, STAT2 KO HeLa cell line, STAT3 KO HeLa cell line, STAT5a KO HeLa cell line, STAT5b KO HeLa cell line, and STAT6 KO HeLa cell line. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for STAT5b at approximately 85 kDa (as indicated) in the parental HeLa cell line, but is not detectable in the STAT5b knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Western blot shows lysates of HAP1 human near-haploid cell line and STAT5b knockout HAP1 cell line (KO). Nitrocellulose membrane was probed with 1 µg/mL of Rabbit Anti-Human/Mouse/Rat STAT5b Monoclonal Antibody (Catalog # MAB15841) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody. A specific band was detected for STAT5b at approximately 85 kDa (as indicated) in the parental HAP1 cell line, but is not detectable in knockout HAP1 cell line. The Ponceau stained transfer of the blot is shown. This experiment was conducted under reducing conditions. Image, protocol, and testing courtesy of YCharOS Inc. See ycharos.com for additional details.

Immunoprecipitation was performed on cell lysate of HAP1 human near-haploid cell line using 2.0 μg of Rabbit Anti-Human Stat5b Monoclonal Antibody (Catalog # MAB15841) pre-coupled to protein G or protein A beads. Immunoprecipitated Stat5b was detected with a Mouse Anti-Stat5b antibody. The Ponceau stained transfers of each blot are shown. SM=10% starting material; UB=10% unbound fraction; IP=immunoprecipitated. Image, protocol, and testing courtesy of YCharOS Inc. (ycharos.com).

Background

Signal Transduction and Activator of Transcription 5 (STAT5) is a member of the Jak/STAT signal transduction pathway and is activated by a variety of cytokines (IL‑22, IL-6, IFN-alpha ). STAT5 has two isoforms (A and B) that share 93% amino acid identity and bind the DNA consensus site TTCN₃GAA. STAT5 mediates cytokine signaling by acting as a signal transducer in the cytoplasm and, upon phosphorylation, translocates to the nucleus and activates transcription of specific genes. STAT5 is involved in a wide array of biological processes ranging from regulating apoptosis to adult mammary gland proliferation, differentiation, and survival.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
