About this peptide

Bacteriostatic water for injection (BWFI), commonly called bac water, is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The preservative suppresses bacterial growth, which makes it the usual diluent when a reconstituted vial will be punctured more than once. Use plain sterile water instead where benzyl alcohol could interfere with the experiment (for example in some cell-culture or preservative-sensitive assays). Supplied as a 10-pack of vials; dedicate each vial to one peptide to avoid cross-contamination.
