Valinomycin is a potassium-specific ionophore, the valinomycin-K⁺ complex can be incorporated into biological bilayer membranes with the hydrophobic surface of valinomycin, destroys the normal K⁺ gradient across the membrane, and as a result kills the cells, incorporating into liposomes can significantly reduces the cytotoxicity and enhances the targeting effect. Valinomycin exhibits antibiotic, antifungal, antiviral, antitumor and insecticidal efficacy, thus can be used for relevant research.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

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.
