Selection Antibiotics. Synonym: Blasticidin S

M.W.: 458.9
Assay: ≥98%

Blasticidin is an antibiotic commonly used in gene selection. Blasticidin is active against both propkaryotic and eukaryotic. Resistance to blasticidin is conferred by the blasticidin resistence gene from bacillus cereus (bsr), bls or BSD. Bsr codes for blasticidin deaminase.

Blasticidin S is used as a selection agent for transformed cells that contain the resistance genes bls, bsr, or BSD. Blasticidiin S has been used to select HEK293-T cells with TLR-2 constructs and HEK-D5 cells . It is also used to study protein synthesis at the level of peptide bond formation.
