Melittin is the principal active peptide of honeybee venom, a 26-amino-acid amphipathic peptide studied in membrane and antimicrobial research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Melittin is investigated in research on membrane perturbation, antimicrobial activity, cell-signaling and venom-peptide biology, and is commonly applied in cell-based and biophysical studies. The lyophilized presentation provides good stability and reproducible reconstitution for consistent experimental dosing. We maintain strict quality control across batches and provide COA for specific batches on request. The unopened product should be stored sealed at 2-8 degree C, protected from light and moisture; for long-term storage keep at -20 degree C and avoid repeated thawing. Small and large orders are accepted, and OEM, private-label and discreet neutral-packaging services are available with worldwide delivery. Laboratory research use only, not for human or veterinary purposes.
