The BL21 (Rosetta) Agar Stab is an E. coli strain specially engineered for the robust expression of recombinant proteins that contain codons rarely used in E. coli. This strain carries extra copies of genes encoding tRNAs that recognize such codons, ensuring higher expression levels of proteins from genes of non-bacterial origin. The strain is provided in agar stab form for prolonged storage and straightforward transformation.
