Pseudomonic acid is a potent antibiotic produced by Pseudomonas fluorescens reported by Fuller et al. in 1971. Pseudomonic acid has broad spectrum activity against Gram positive bacteria and was approved for topical human use in 1985. Pseudomonic acid acts as a potent and selective inhibitor of isoleucyl-tRNA synthetase.

Soluble in ethanol, methanol, DMF or DMSO. Limited water solubility

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage store at -20C. Aliquots are stable for 6 months after receipt at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
