While PTBP1 is widely expressed, PTBP2, also known as neural PTB or nPTB, is expressed in post-mitotic neurons. In other cell types, PTBP2 transcripts are alternatively spliced by PTBP1, which leads to nonsense-mediated decay. PTBP1 and 2 bind to similar regions across the transcriptome, but PTBP1 has a stronger repressive property likely due to cofactors such as Raver1 and Matrin3. Overexpression of PTBPs in various cancers has been observed, leading to alternative splicing of key proteins in oncogenic pathways.\u003c\/p\u003e\n\n\u003cp\u003eProduct: Liquid in 50mM Tris-Glycine (pH 7.4), 0.15M NaCl, 50% Glycerol, 0.01% Sodium azide and 0.05% BSA.\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was purified by immunogen affinity chromatography.\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: Recognizes endogenous levels of hnRNP I protein.\u003c\/p\u003e\n\n\u003cp\u003eNote: For research use only, not for use in diagnostic procedure.\u003c\/p\u003e\n\n\u003cp\u003eExtra Notes: Western blot analysis of hnRNP I expression in Hela (A), CHOK1 (B), Ramos (C), NIH3T3 (D) whole cell lysates., Immunohistochemical analysis of hnRNP I staining in human tonsil formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.130). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.\u003c\/p\u003e \n\n\u003cp\u003eBioworld Molecular Weight: ~ 57 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
