Protein expression E. coli / BL21 strains / BL21(DE3) chemically competent cells
Chemically competent BL21(DE3) cells with T7 expression capability; lon and ompT deficient, phage T1 resistant. Compare host genotype and induction conditions.
Protein expression E. coli / BL21 strains / BL21 chemically competent cells without DE3
Chemically competent BL21 cells without DE3 for non-T7 expression vectors. lon and ompT deficient; this is not a T7-polymerase expression host.
Protein expression E. coli / BL21 strains / BL21 chemically competent cells without DE3
Candidate only. Verify activity, specificity, formulation and protocol compatibility before substitution. Protein-expression E. coli BL21; DE3/T7 requirements must be matched.
Protein expression E. coli / BL21 strains / BL21 chemically competent cells without DE3
Classification is based on the supplied product name. Confirm formulation, application and compatibility in the manufacturer documentation.
Protein expression E. coli / BL21 strains / BL21 chemically competent cells without DE3
Chemically competent BL21 cells without T7 RNA polymerase expression. Intended for compatible non-T7 expression systems.
Protein expression E. coli / T7 expression strains / BL21(DE3) chemically competent cells
Candidate only. Verify activity, specificity, formulation and protocol compatibility before substitution. DE3 lysogen supplies T7 RNA polymerase; NEB T7 Express variants have different genotype and toxicity controls.
Protein expression E. coli / BL21 strains / BL21(DE3) chemically competent cells
BL21(DE3) chemical transformation cells for T7-promoter expression. No pLysS plasmid is specified; follow the supplier direct-plating protocol.

Final groups are designed around experimental substitution requirements. Group membership is provisional until the necessary technical details have been verified for the intended experiment.
Start with your application, then verify the technical requirements against each manufacturer’s documentation.
