| Description: |
Gramicidin S is a cyclic peptide antibiotic produced by Bacillus brevis var. Gause-Brazhnikova. Gramicidin S exerts antibacterial activity by destroying membrane integrity and interfering with membrane protein function. Gramicidin S also inhibits ion channels, with IC50s of 41 μM, 24 μM, and 3 μM for Na+/K+-ATPase, tobacco leaf plasma membrane Mg2+/K+-ATPase, and rat heart plasma membrane Ca2+-ATPase, respectively. |
| Stability and Solubility Advice: |
Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
