{"product_id":"abm175828","title":"SAP 155 Polyclonal Antibody","description":"\u003ch3\u003eBackground\u003c\/h3\u003e\u003cp\u003eSF3B1 encodes subunit 1 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b\/3a complex binds pre-mRNA upstream of the intron's branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome. The carboxy-terminal two-thirds of subunit 1 have 22 non-identical, tandem HEAT repeats that form rod-like, helical structures. Alternative splicing results in multiple transcript variants encoding different isoforms.\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"20ul","offer_id":57659740488020,"sku":"ABM175828","price":69.0,"currency_code":"GBP","in_stock":true},{"title":"50ul","offer_id":57659740520788,"sku":"ABM175829","price":115.0,"currency_code":"GBP","in_stock":true},{"title":"100ul","offer_id":57659740553556,"sku":"ABM175830","price":176.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1040\/1782\/2036\/files\/btlab-b53bec5c7e9f2b52716cb2d1eefa5087fc9dd31d1298a9655d806fb02a0547a6.jpg?v=1792158818","url":"https:\/\/www.abmium.com\/products\/abm175828","provider":"ABMIUM","version":"1.0","type":"link"}
