Thymalin 20 mg

Thymalin for research: identity and specifications

Thymalin is a peptide preparation of the Khavinson class of thymic bioregulators, originally derived from thymus peptide extracts and studied in preclinical models of immune cell signaling. Supplied as a 20 mg vial of lyophilized powder, with no fillers, carriers or excipients, at ≥98% purity by HPLC, with the identity and purity of each lot documented on its certificate of analysis.

Scientific background

Thymic peptide preparations are used in experimental models of immune signaling, lymphocyte maturation and communication between immune cells. Thymalin belongs to the group of short-peptide bioregulators studied by the research group of Prof. Vladimir Khavinson, which are investigated for effects on gene expression and cell differentiation in vitro.

These observations come from preclinical and cell culture work, always under controlled bench conditions and without extrapolating results to human or veterinary use.

• Thymic peptide signaling in immune cell models
• Lymphocyte maturation in vitro
• Immune cell communication pathways
• Khavinson-class bioregulators in tissue aging models

Technical specifications

Analytical quality and chain of custody

Every lot of Thymalin is synthesized in registered facilities, with independent analytical verification by third-party laboratories and full chain-of-custody documentation. The certificate of analysis (COA) for each lot can be reviewed before purchase, recording HPLC purity and the other quality-control parameters used to release the material.

Reconstitution and laboratory handling

As a bench procedure, the lyophilized vial is reconstituted with a known volume of a suitable solvent, added along the inner wall of the vial, followed by gentle swirling until fully dissolved, without vigorous shaking. The reconstituted solution should be kept refrigerated and protected from light, and used in controlled assays within the stability period validated by the laboratory. Handling must be performed only by qualified personnel, in a bench environment suitable for in vitro experimentation, with lot number and storage conditions documented according to good laboratory practice.

Frequently asked questions

What is the purity of the Thymalin supplied?

≥98% by HPLC, with the lot-specific value reported on the certificate of analysis (COA).

Is Thymalin the same as thymulin?

No. Thymulin is a different, zinc-dependent thymic nonapeptide with its own PubChem record. Thymalin is a separate thymic bioregulator preparation, and the lot COA documents the material supplied.

How should the compound be stored?

At -20 °C, protected from light and moisture, as a lyophilized powder until reconstitution.

Does the certificate of analysis come with the lot?

Yes, every lot has a matching COA that can be verified before purchase using the button on this page.
