In Vitro

Rebeccamycin is an antitumor antibiotic produced by the actinomycete Saccharotrix aerocolonigenes with activity against several human tumor cell lines, including A549 (lung adenocarcinoma), HCT-116 (colon carcinoma), and KB (nasopharyngeal carcinoma) ^[1].
Rebeccamycin shows antibacterial activity against several Gram-positive bacteria, including Staphylococcus aureus and Streptococcus faecalis^[3].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
