For peptides that do not dissolve cleanly in bacteriostatic water alone typically those with hydrophobic sequences or basic amino acid-rich compositions that require protonation for solubilisation the recommended approach is to first perform initial reconstitution in a small volume of 0.1% acetic acid water (also available from Peptides Lab UK) to produce a clear stock solution, before diluting further with bacteriostatic water or the relevant physiological buffer
When to Use BAC Water BAC water is the right choice when: Your protocol requires multiple draws from the same vial You need a stable solution over days or weeks Isotonicity is not a requirement of your experimental design Your compound is compatible with benzyl alcohol Cost and efficiency across multiple preparations matter If you use BAC water regularly, buying bac water in the right pack size helps reduce your cost per vial
