Crystagen: research overview
Crystagen 20 mg is a short peptide from the bioregulator group, supplied as a research reagent in lyophilized form. Every batch has a purity of 99% or higher (HPLC) and a molecular mass confirmed by MS. You start working with verified material from the first opening.
What Crystagen is
Structure and origin
Crystagen is a peptide, a short chain of amino acids linked by peptide bonds. It belongs to the bioregulators described in the work of Khavinson, a research line that studied short peptides as regulators of cell activity in particular body systems. Within this group, Crystagen stands out because the literature describes it as a bioregulator of the immune system.
Mechanism described in research
The bioregulation concept assumes that short peptides can influence cell activity. For Crystagen, the published work focuses mainly on cells of the immune system. The exact mechanism of action is not yet fully described, so results are best interpreted within a clearly designed research project with proper controls.
Research areas
- immune cell activity in cell culture models,
- immune response in animal models,
- comparative studies of Khavinson bioregulators from different body systems,
- preparation, storage and reconstitution of peptides in the laboratory.

Working in the laboratory
Peptide stability depends on storage conditions, so it pays to follow a few simple rules:
- keep the lyophilized powder at -20 °C in a sealed container, away from light and moisture,
- once reconstituted, keep the solution at 2-8 °C,
- avoid repeated freezing and thawing, which shortens the stability of the peptide,
- before opening the vial, let it reach room temperature to prevent moisture from condensing inside.
The role of the solvent
The basic solvent is water, preferably bacteriostatic water prepared for laboratory work. When the peptide dissolves poorly in water, a diluted acetic acid solution helps dissolve the material before you prepare the working solution. Solubility depends on the peptide composition, so test the first solution with a small amount of material. You can check your dilutions in the concentration calculator.
Quality of every batch
Each Crystagen batch is documented by two results:
- HPLC: purity of 99% or higher,
- MS: confirmation of molecular mass
