INTACT GENOMICS INC IG C43(DE3)pLysS Chemically Competent Cells 6x50µl
These chemically competent cells are engineered for high-efficiency transformation and stable expression of toxic or difficult proteins within IPTG-inducible T7 systems. Derived from BL21(DE3), this strain offers improved tolerance to toxic proteins, while the pLysS plasmid works to suppress basal expression, thereby stabilizing challenging constructs.
- T7 expression strain
- Selected for expression of toxic proteins
- Suitable for expression of toxic genes
- Chloramphenicol-resistant (12.5 μg/ml)
- High-efficiency transformation
- Improved tolerance to toxic proteins
- Suppresses basal expression of T7 RNA polymerase
INTACT GENOMICS INC Recombineering Chemically Competent Cells 6x50µl
Intact Genomics (IG™) Recombineering Chemically Competent Cells enable high-efficiency transformation for DNA, plasmid, and BAC engineering, and homologous recombination. Derived from SW102 (a DH10B background strain), they feature a defective lambda prophage and a galK deletion for efficient DNA/BAC modification via galK positive/negative selection. The cells are tetracycline resistant (5 μg/mL).
- High transformation efficiency.
- Supports DNA, plasmid, and BAC engineering, plus homologous recombination.
- Enables precise modification using galK positive/negative selection.
- Derived from SW102 (DH10B background).
- Heat-inducible prophage with red genes (exo, bet, gam), repressed at 32 °C and induced at 42 °C.
- Tetracycline resistant (TetR: 5 μg/ml).
