EMD Millipore Novagen Origami 2 Competent Cells
Manufacturer: Millipore Sigma 713444
DescriptionOrigami 2 host strains are K-12 derivatives that have mutations in both the thioredoxin reductase (trxB) and glutathione reductase (gor) genes, which greatly enhance disulfide bond formation in the E. coli cytoplasm. The Origami 2 strains are kanamycin sensitive; like the original Origami strains, the gor mutation is still selected for by tetracycline. To reduce the possibility of disulfide bond formation between molecules, strains containing mutations in trxB and gor are recommended only for the expression of proteins that require disulfide bond formation for proper folding.
