Antibiotic MX 2

Antibiotic MX 2 is an orally active antibiotic that can cross the blood-brain barrier. Antibiotic MX 2 inhibits the growth of drug-sensitive and multidrug-resistant tumor cells, prolongs the survival of tumor-bearing mice, induces single-strand and double-strand DNA breaks, suppresses colony formation of fresh human-derived tumor cells, and overcomes multidrug resistance mediated by P-glycoprotein. Antibiotic MX 2 can be used in research related to L1210 leukemia, Lewis lung cancer, colon adenocarcinoma type 26 and type 38, gastric adenocarcinoma, non-small cell lung cancer, mammary adenocarcinoma, drug-resistant P388 leukemia, renal cancer, melanoma, ovarian cancer, breast cancer, small cell lung cancer, and colorectal cancer.

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.
