Technical Glossary

An analytical technique used to separate, identify, and quantify each component in a mixture. In peptide research, it is the gold standard for verifying sequence purity (>99%).

An analytical tool used to measure the mass-to-charge ratio of ions. It confirms the absolute molecular identity and weight of a synthetic peptide sequence.

A dehydration process (freeze-drying) used to preserve peptides in a stable, solid state. It involves freezing the material and then reducing the surrounding pressure to allow the frozen water to sublime directly from the solid phase to the gas phase.

The exact arrangement of amino acids in a peptide chain. Verified through MS/MS fragmentation to ensure the synthetic product matches the target research sequence.

The mass of a given substance divided by the amount of substance. For peptides, precise molar mass (g/mol) is critical for calculating volumetric concentrations during reconstitution.

Sterile water containing 0.9% benzyl alcohol as a preservative. Used in laboratory settings to reconstitute lyophilized peptides for multi-use experimental vials.

Short-chain peptides (typically 2-4 amino acids) that act as epigenetic modulators to normalize gene expression and cellular function in specific tissues.

Organic compounds that combine to form proteins and peptides. The sequence of AAs determines the specific biological activity of the resulting peptide.

The percentage of acetic acid remaining in a peptide after purification. Most research peptides are provided as acetate salts to maintain stability and solubility.

The actual weight of the peptide sequence in a vial, excluding moisture, salts (like acetate), and counter-ions. Critical for precise experimental dosing.
