Acetic Acid 0.6%: research overview
Acetic Acid 0.6% for peptides is a ready-made solvent in sterile water, made for the moments when a peptide refuses to dissolve in neutral water. Available in 3 ml and 10 ml vials.
What Acetic Acid 0.6% is
Acetic acid is the carboxylic acid that gives vinegar its sour taste. It forms naturally during fermentation and is also produced on an industrial scale, which makes it one of the most widely used acidic reagents in research.
Our product is a solution of acetic acid at 0.6% in sterile water. The low concentration makes it easy to match the medium to the requirements of a specific experiment, while the acidity stays at a predictable level.
Mechanism described in research
Peptides are built from amino acids, and some of them are basic, for example lysine, arginine and histidine. In a mildly acidic medium these groups become protonated, which increases the interaction between the peptide and water. The effect is most visible for molecules that form a precipitate or aggregates in neutral water.
The acid changes the dissolution conditions, not the amino acid sequence of the peptide. For that reason, in research work it is treated as a tool for preparing a solution, not as a component of the compound under study.
Areas of research
- dissolving basic peptides in in vitro work
- preparing working solutions at a controlled pH
- formulation studies that compare peptide solubility under different conditions
- preparing samples before chromatographic and mass spectrometry analysis

Working in the laboratory
Role of the solvent
Sterile water and Acetic Acid 0.6% act as solvents. They are not a component of the lyophilised material under study, only the medium in which the peptide goes into solution. You can convert volume and concentration with the concentration calculator.
Storage
- Lyophilised peptide: store at -20 °C, tightly sealed and protected from light.
- Solution after reconstitution: store at 2-8 °C.
- Freezing: avoid repeated freezing and thawing, and divide the solution into smaller portions.
- Acetic Acid 0.6%: keep the vial tightly closed, following the storage note on the batch label.
Batch quality
We run HPLC to assess purity and mass spectrometry (MS) to confirm mass wherever these methods apply. You can read about our quality control on the quality page.
