Description

Acetic Water 10ml — Laboratory Reconstitution Solvent

Acetic Water 10ml is a dilute solution of acetic acid in water, supplied sterile in a sealed, tamper-evident 10 ml glass vial. It is a laboratory solvent, not a research peptide: it is listed for the reconstitution of lyophilised research materials that dissolve poorly in neutral aqueous solvents, where a mildly acidic medium is the conventional choice. It sits in the Laboratory Supplies category with Bacteriostatic Water 10ml and the pen needles.

Why an Acidic Solvent

Peptide solubility depends on net charge. Sequences that carry little net charge at neutral pH, or that are hydrophobic, can aggregate or fail to wet, whereas a mildly acidic solution protonates basic side chains and the N-terminus, raising net positive charge and, for many such sequences, solubility. Dilute acetic acid is the conventional laboratory choice because it is volatile and compatible with downstream chromatography. Which solvent suits a given material is a property of that material; the handling and storage guides cover solvent selection, and this page gives no volumes or concentrations for any specific compound.

Handling

Draw the required volume under sterile conditions with appropriate laboratory equipment. Because no preservative is stated for this presentation, treat an opened vial as short-term stock rather than a multi-use reservoir. Discard any vial whose contents appear cloudy or contain particulates.

Documentation

Each vial carries a lot number, and batch documentation for the lot supplied is available on request.
