Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nHeterogeneous nuclear ribonucleoprotein A2\/B1 (hnRNP A2\/B1) is a member of the hnRNP A\/B family of related RNA-binding proteins that bind pre-mRNA and are involved in the processing, metabolism, and transport of nuclear pre-mRNA transcripts (1). Alternative splicing produces transcripts that encode two homologous hnRNP proteins, hnRNPA2 and hnRNPB1, from a single gene sequence (2). Studies demonstrate hnRNP A2\/B1 splicing repression across multiple targets (3,4) and that both proteins can bind and protect telomere repeat sequences from DNase digestion (5,6). Altered expression of hnRNP B1 is seen in several forms of cancer, including squamous cell carcinoma, adenocarcinoma, and various forms of lung cancer (7). Overexpression of hnRNP B1 may be associated with inhibition of DNA-PK activity and impaired DNA repair during early stages of cancer development (8). Autoantigens to hnRNP A2\/B1 (termed RA33) are associated with rheumatoid arthritis, systemic lupus erythematosus, and mixed connective tissue disease (9-11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDKFZp779B0244; epididymis secretory sperm binding protein; FLJ22720; heterogeneous nuclear ribonucleoprotein A2\/B1; heterogeneous nuclear ribonucleoprotein B1; Heterogeneous nuclear ribonucleoproteins A2\/B1; hnRNP A2 \/ hnRNP B1; hnRNP A2\/B1; HNRNPA2; HNRNPA2B1; HNRNPA2B1\/MYC fusion; HNRNPB1; HNRPA2; HNRPA2B1; HNRPB1; IBMPFD2; nuclear ribonucleoprotein particle A2 protein; RNPA2; ROA2; SNRPB1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 34-36\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797896876201,"sku":"25734S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-25734s","provider":"Iright","version":"1.0","type":"link"}
