菌株簡介:
Origami B host strains carry the same mutations in trxB and gor as the original Origami strains, except that they are derived from a lacZY mutant of BL21 to enable precise control of expression levels by adjusting the concentration of IPTG. Thus the Origami B strains combine the desirable characteristics of BL21, Tuner?, and Origami strains in one strain background. The mutations in trxB and gor are selectable on kanamycin and tetracycline, respectively; therefore, these strains cannot be used with plasmids that can only selected with kanamycin or tetracycline. These strains also include the lon and ompT deficiences of BL21, which increase protein stability.
DE3 indicates that the host is a lysogen of λDE3, 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.
pLysS strains express T7 lysozyme, which further suppresses basal expression of T7 RNA polymerase prior to induction, thus stabilizing pET recombinants encoding target proteins that affect cell growth and viability.
注意事項(xiàng):
1、為了您的**和健康,請穿實(shí)驗(yàn)服并戴一次性手套操作。本產(chǎn)品僅可用于實(shí)驗(yàn)室研究,不能用于動(dòng)物,人體以及作為食品添加劑等用途。
2、使用甘油菌時(shí)可不完全融解,在甘油菌表面蘸取少量涂布固體瓊脂平板即可,也可完全融解后使用,但隨著凍融次數(shù)的增加,菌株的活力會(huì)逐漸下降。
