Selection antibiotic: cell culture tested, sterile reagent

Blasticidin is an efficient selection antibiotic that acts on both eukaryotic ａnd prokaryotic cells.

Blasticidin is a peptidyl nucleoside antibiotic isolated from Streptomyces griseochromogenes that inhibits protein synthesis by interfering with the peptide-bond formation in the ribosomal machinery.

Resistance to blasticidin is conferred by the blasticidin resistance gene from Bacillus cereus (bsr), which codes for blasticidin-S deaminase [1].
Resistance to blasticidin is also conferred by the blastcidin S acetyltransferase gene (bls) from Streptoverticillum sp [2], ａnd the blasticidin S deaminase gene (BSD) from Apergillus terreus [3].

Typically, mammalian cells are sensitive to blasticidin concentrations of 1-10 µg/ml, ａnd bacteria to 25-100 µg/ml.
Cell death induced by blasticidin occurs rapidly, allowing for selection of transfected cell lines carrying a blasticidin resistance gene within one week.

WORKING CONCENTRATIONS

The working concentration of blasticidin for mammalian cell lines varies from 1 to 10 μg/ml, in a few cases up to 30 μg/ml.
In a starting experiment, we recommend determining optimal concentrations of antibiotic required to kill your host cell line.
After treatment, cell death occurs rapidly, allowing the selection of transfected cells with plasmids carrying the bsr or BSD genes in as little as 7 days post-transfection.
Suggested concentrations of blasticidin for selection in some examples of mammalian cells are listed below.
