Antibodies are purified by peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nOct-4 (POU5F1) is a transcription factor highly expressed in undifferentiated embryonic stem cells and embryonic germ cells (1). A network of key factors that includes Oct-4, Nanog, and Sox2 is necessary for the maintenance of pluripotent potential, and downregulation of Oct-4 has been shown to trigger cell differentiation (2,3). Research studies have demonstrated that Oct-4 is a useful germ cell tumor marker (4). Oct-4 exists as two splice variants, Oct-4A and Oct-4B (5). Recent studies have suggested that the Oct-4A isoform has the ability to confer and sustain pluripotency, while Oct-4B may exist in some somatic, non-pluripotent cells (6,7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nMGC22487; Oct-3; Oct-4; OCT3; OCT3A; OCT4; OCT4A; Octamer-binding protein 3; Octamer-binding protein 4; Octamer-binding transcription factor 3; octamer-binding transcription factor-3; OTF-3; OTF3; OTF4; PO5F1; POU class 5 homeobox 1; POU class 5 homeobox 1 transcript variant OCT4B1; POU class 5 homeobox 1 transcript variant OCT4B2; POU class 5 homeobox 1 transcript variant OCT4B3; POU class 5 homeobox 1 transcript variant OCT4B4; POU class 5 homeobox 1 transcript variant OCT4B5; POU class 5 homeobox 1 transcript variant OCT4B6; POU classV homeobox 1 variant 2; POU domain transcription factor OCT4; POU domain, class 5, transcription factor 1; POU-type homeodomain-containing DNA-binding protein; POU5F1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 45\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797979189417,"sku":"2750S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2750s","provider":"Iright","version":"1.0","type":"link"}
