纯度规格：Origami B host strains carry the same mutations as the original Origami strain, except that they are derived from a lacZY mutant of BL21 to enable precise control of expression levels using IPTG.
纯度规格：Novagen′s PhosphoSafe Extraction Buffer efficiently extracts cytosolic proteins from mammalian and insect cells while preserving their phosphorylation state.
纯度规格：Rosetta-gami B strains combine the key features of BL21, Origami, and Rosetta to enhance both the expression of eukaryotic proteins and the formation of target protein disulfide bonds.
