I'm looking for the decapeptide Gramicidin S (a
circular variant of the Gramicidin family), but
I'm having trouble finding some company which
sells it.
I called Sigma-Aldrich and they told me that they
stopped selling it last year (they used to have
it). I also tried Calbiochem and Bachem with
negative results.
So does anyone have another idea?
Thanks,
Thomas
