BL21-CodonPlus strains are engineered to contain extra copies of genes that encode the tRNAs that most frequently limit translation of heterologous proteins in E.coli.

  •  Dramatically improves expression when codon bias is a problem
  •  RIL strain for AT-rich genomes and RP strain for GC-rich genomes
  •  For proteins from all organisms, not just mammalian
  •  Overcomes codon bias problems
  •  Expresses all rare     E.coli    codons
  •  Ideal for difficult protein expression
