Blasticidin S HCl is a nucleoside antibiotic derived from Streptomyces griseochromogenes. Blasticidin S HCl is routinely used in cell culture gene selection applications as a selection agent to isolate mammalian cells containing the blasticidin S-resistance (bsr) gene.

Blasticidin S HCl solution contains 10 mg/mL blasticidin S HCl in 20mM HEPES. 10 x 1 mL contains 10 mg blasticidin S HCl per vial (100 mg total). 20 mL contains 200 mg blasticidin S HCl.

    CAS Number


    Molecular Formula

    C17H26N8O5 · HCl

    Molecular Weight

    458.90 g/mol

    Mechanism of Action

    Blasticidin S HCl inhibits protein synthesis in prokaryotic and eukaryotic cells by binding to the ribosomal P-site.. Blasticidin S HCl strengthens tRNA binding to the P-site which slows down and prevents subsequent peptide synthesis.
