B834(DE3) Competent Cells – Novagen

Descrição detalhada : B834 is the parental strain for BL21. These hosts are methionine auxotrophs and allow high specific activity labeling of target proteins with 35S-methionine and selenomethionine for crystallography., Genotype: F-ompT hsdSB(rB- mB-) gal dcm met (DE3)This product contains genetically modified organisms (GMO). Within the EU GMOs are regulated by Directives 2001/18/EC and 2009/41/EC of the European Parliament and of the Council and their national implementation in the member States respectively. This legislation obliges us to request certain information about you and the establishment where the GMOs are being handled. Click here for Enduser Declaration (EUD) Form., B834 is the parental strain for BL21 (1). These protease-deficient hosts are methionine auxotrophs and allow high specific-activity labeling of target proteins with 35S-methionine and selenomethionine for crystallography (2).DE3 indicates that the host is a lysogen of lambdaDE3, and therefore carries a chromosomal copy of the T7 RNA polymerase gene under control of the lacUV5 promoter. Such strains are suitable for production of protein from target genes cloned in pET vectors by induction with IPTG.
