BL21-CodonPlus (DE3)-RILP Competent Cells by Agilent Technologies
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
