OverExpress™ C41(DE3) and C43(DE3) Competent Cells » Express difficult or even toxic proteins using any E. coli T7 vector. Available as chemically competent or electrocompetent cells.
E. cloni® EXPRESS BL21(DE3) Competent Cells » For routine protein expression using any E. coli T7 expression vector. Available as chemically competent or highest efficiency electrocompetent cells.
HI-Control™ BL21(DE3) and HI-Control™ 10G Competent Cells » Greater control of protein expression using the LacI repressor in two popular cell lines.
Eliminate endotoxin at the source. These genetically modified E. coli competent cells lack the key signal for triggering pro-inflammatory cytokines and immune system activation. Significantly decreases the time, cost and effort related to endotoxin removal while increasing the reliability of experimental results.
ClearColi® K-12 Electrocompetent Cells » Eliminate endotoxin in your plasmid prep without expensive endo-free prep kits. These E. coli competent cells have a modified LPS that eliminates poor transfection or mammalian protein expression due to endotoxin contamination.
Custom Competent Cell Preparation Services » Highest efficiency cells produced from any strain. Quick production time—usually under two weeks.
Recovery Medium » Refined formulation ensures the highest possible transformation efficiency. Delivers 10-fold higher efficiency than traditional SOC.
Expression Recovery Medium » Optimized formulation for ensuring stability and high-efficiency transformation of protein expression clones.
