In Vitro

Geministatin B exhibits potent antibacterial activity against Bacillus subtilis (MIC = 0.39 µg/mL), Staphylococcus aureus (MIC = 3.1 µg/mL), and MRSA (MIC = 1.6 µg/mL)^[1].
Geministatin B shows no antifungal activity against Saccharomyces cerevisiae with MIC > 200 µg/mL^[1].
Geministatin B shows low cytotoxicity against mouse myeloma NS-1 cells (IC₅₀ = 93 µM) and neonatal foreskin fibroblast cells (IC₅₀ >190 µM)^[1].

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.
