Research Background
Thymalin is a thymic peptide preparation used in published immune-modulation research, particularly studies of T-cell maturation and of the neuroendocrine–immune interface. Note that the name is applied inconsistently in the literature and in public databases: some records resolve it to the nonapeptide thymulin, while commercial preparations may be defined as thymus-derived peptide complexes. Because of that ambiguity, this catalogue does not publish a fixed CAS number and instead confirms identity per batch.
Proposed Mechanisms
Research Focus Areas
T-cell maturation and lymphocyte-population research
Thymic factors and endocrine cross-talk
Thymic involution and immune-senescence models

FAQ
Why is there no fixed CAS number for Thymalin?
The name is used for more than one type of thymic peptide preparation, and public databases resolve it inconsistently. Identity is therefore confirmed per batch on the COA rather than quoted as a catalogue CAS number.
Is Thymalin the same as thymulin?
Not necessarily. Some database entries list the two names as synonyms, but commercial thymic preparations can be defined differently. Check the composition statement on the COA against the publication you are replicating.
What is the purity specification?
The catalogue specification is ≥99% by HPLC, with the measured value for your lot stated on the batch Certificate of Analysis.
How should Thymalin be handled?
Store the lyophilized powder at 2–8 °C, desiccated and protected from light. Reconstitute with sterile or bacteriostatic water and establish your own solution-stability data.
What kit sizes are available?
Thymalin is supplied as 10 mg × 10 vials, with tiered wholesale discounts from 10% at 5+ kits to 30% at 50+ kits; custom configurations are available for OEM projects.
