Relevance:

Heterodimer protein that may serve both defensive (pain-inducing) and predatory (insecticidal) roles (PubMed:28513074). Has membrane-disrupting activity and shows induction of non-specific calcium influx into cells, (PubMed:28513074). Shows broad-spectrum activity against a diverse range of bacteria, and cell lines, as well as hemolytic activity (EC(50)=2.18 µM) (PubMed:28513074). In vivo, shows moderate insecticidal activity against D.melanogaster and potent anthelmintic activity against the veterinary nematode H.contortus (PubMed:32629771). In addition, intraplantar injection into mice induces nocifensive behavior and mechanical allodynia (PubMed:28513074).

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
