产品简介：
Rosetta(DE3) pLysS host strains are BL21 derivatives designed to enhance the expression of eukaryotic proteins that contain codons rarely used in E. coli. These strains supply tRNAs for AGG, AGA, AUA, CUA, CCC, GGA codons on a compatible chloramphenicol-resistant plasmid. In Rosetta(DE3)pLysS, the rare tRNA genes are present on the same plasmids that carries the T7 lysozyme gene. 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.

注意事项：
1、为了您的安全和健康，请穿实验服并戴一次性手套操作。本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗等其他用途。
2、使用甘油菌可不完全融解，在菌液表面蘸取少量涂布固体琼脂平板即可。完全融解后使用，菌体会逐渐沉淀至管底，请混匀后使用。随着冻融次数的增加，菌株的活力会逐渐下降。
