4.6mg/ml Taking the 1 mL working solution as an example, add 50 μL 92 mg/mL clarified H2O stock solution to 400 μL PEG300, mix evenly to clarify; add 50 μL Tween-80 to the above system, mix evenly to clarify; Then continue to add 500 μL ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Blasticidin S HCl is a nucleoside antibiotic isolated from Stretomyces girseochromogenes. It acts by blocking hydrolysis of peptidyl-tRNA induced by release factors and inhibits peptide bond formation. It is used to select transfected cells carrying bsr or BSD resistance genes.
Targets
protein synthesis [1] DNA synthesis [1]
In vitro

Blasticidin S inhibits protein synthesis by acting on the step of peptide transfer from peptidyl-sRNA to incoming aminoacyl-sRNA. [1]

Blasticidin S also significantly inhibits DNA synthesis independent of their effect on protein synthesis. [2]

Blasticidin S kills the cells more rapidly than G418, which makes blasticidin S-resistance gene (bsr) a selectable marker for mammalian cells. [3]

Besides, Blasticidin S also efficiently binds Cu(II) ions and prevents DNA from metal-induced damage. [4]
In vivo

Blasticidin S HCl is an antibiotic isolated from Stretomyces girseochromogenes that acts as a protein synthesis inhibitor. It is used to select transfected cells carrying bsr or BSD resistance genes.
