{"product_id":"new-product-274855","title":"TFIIE-β polyclonal antibody","description":"\u003cp\u003eIn eukaryotic systems, initiation of transcription from protein-coding genes is a complex process requiring RNA polymerase II and broad families of auxiliary transcription factors. Such factors can be divided into two major functional classes: the basal factors that are required for transcription of all Pol II genes, including TFIIA, TFIIB, TFIID, TFIIE, TFIIF and TFIIH; and sequencespecific factors that regulate gene expression. The basal transcription factors and Pol II form a specific multiprotein complex near the transcriptional start site by interacting with core promotor elements such as the TATA box generally located 25-30 base pairs upstream of the transcription start site. Human TFIIE consists of two subunits of 56 kDa and 34 kDa molecular weight, respectively. The structure of TFIIE appears to be a heterotetramer(α2 β2) both subunits being required for optimal basal-level transcription .\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45804701647128,"sku":"ABCBW02945","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_0dd73454-06af-4e80-b3b3-f1f87221931c.png?v=1689738656","url":"https:\/\/danabiosci.com\/products\/new-product-274855","provider":"Dana Bioscience","version":"1.0","type":"link"}
