Activation of Stat5a via IL-2, IL-3, IL-7\/ GM-CSF, erythropoietin, thrombopoietin and growth hormones influences proliferation, differentiation and apoptosis in lymphohematopoietic cells. Phosphorylation of Stat5a at Ser127\/Ser128 and Ser779 are contigent on ErbB-4-mediated activation of Stat5a. Activation of Stat5b via IL-2, IL-4, CSF-1 and growth hormones influences TCR signaling, apoptosis, adult mammary gland development and sexual dimorphism of liver gene expression. Stat5b is the major liver-expressed Stat5 form that has been shown to fuse with the retinoic acid receptor a gene in acute promyelocytic leukemias (APLL). Stat5a\/b null mice have severely impaired lymphoid development and differentiation.\u003c\/p\u003e\u003cp\u003eThis anti-STAT5b antibody is supplied as Purified (Mouse, Monoclonal (mouse origin), clone STAT5B\/2611, Mouse IgG1, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.\u003c\/p\u003e\u003ch2\u003eKey elements and design rationale\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTarget:\u003c\/strong\u003e STAT5b\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalization:\u003c\/strong\u003e Nuclear, cytoplasmic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecies reactivity:\u003c\/strong\u003e Human\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications (listed):\u003c\/strong\u003e IHC-P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConjugate:\u003c\/strong\u003e Unconjugated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone and antibody class:\u003c\/strong\u003e Monoclonal (mouse origin), clone STAT5B\/2611, Mouse IgG1, kappa\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.\u003c\/p\u003e\u003ch2\u003eBiological background\u003c\/h2\u003e\u003cp\u003eSTAT5b is referenced in public gene\/protein resources (e.g., UniProt and NCBI Gene), which provide curated names\/synonyms, protein features, and pathway context.
