Description

Omiganan is a cationic antimicrobial peptide. Omiganan as an analogue of indolicidin shows activity against gram-positive and gram-negative bacteria but also Candida spp. isolates. Omiganan can be used for the research of alcohol nose and acne[1][2].

In Vivo

Omiganan results in a statistically significantly reduction in bacterial counts. omiganan reduces the bacterial counts by 3.8 (S. aureus), 2.2 (S. epidermidis) and 2.3 (C. albicans) log10 CFU/site. Omiganan has rapid bactericidal and fungicidal properties and significant dose-dependent activity against a broad spectrum of infected organisms[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
