Using Bacteriostatic Water in the Lab
Bacteriostatic water is the standard diluent for multi-draw peptide stock solutions: the benzyl alcohol preservative inhibits microbial growth, so a vial can be sampled repeatedly over its in-use period. For assays where benzyl alcohol could interfere — some cell cultures are sensitive to it — use sterile, preservative-free water instead.
Work out diluent volumes and aliquot sizes with our reconstitution calculator, and see the reconstitution guide for technique.
