Why BAC Water for Peptide Research Multi-draw compatibility The 0.9% benzyl alcohol content inhibits microbial growth, allowing multiple sterile withdrawals from the same vial over weeks not possible with plain sterile water, which does not contain a preservative Peptide stability Most lyophilised research peptides reconstitute stably in aqueous solution at neutral pH

They share 64% sequence identity and differ in their catalytic activities
