Blasticidin S HCl Solution 10 mg/mL is a sterile, DNase/RNase-free solution in HEPES buffer. It is a nucleoside antibiotic derived from Streptomyces griseochromogenes with high purity, commonly used in molecular biology, biotechnology, and gene editing applications such as CRISPR. It functions as a selection agent in cell culture by inhibiting protein synthesis in both prokaryotic and eukaryotic cells, allowing for the isolation of successfully modified cells. This product is ideal for creating stable cell lines and expressing recombinant proteins. Store at -20°C and avoid repeated freeze-thaw cycles.
