Biological Activity
Antibiotic DC 81, a pyrrolo(2,1-c)(1,4)benzodiazepine (PBD) antitumor antibiotic produced by Streptomyces species, acts as a potent inhibitor of nucleic acid synthesis. It specifically recognizes and binds to certain DNA sequences, forming a labile covalent adduct (1) (2).
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
It is not recommended to store DMSO stock solutions at room temperature. Once the stock solution is prepared, aliquot into single-use volumes and store at −20 °C (or −80 °C for sensitive compounds). Room-temperature storage accelerates chemical degradation and moisture uptake. When ready to use, thaw an aliquot at room temperature, use immediately, and avoid repeated freeze-thaw cycles.
The concentration of stock solution should be lower than the solubility provided on the official website. Within this range, the concentration of stock solution should be set based on that of working solution. For cell experiments, it is recommended to set the stock solution concentration at least 1000 times higher than that of working solution.
