Overview
Zinc is a structural and catalytic cofactor for several hundred enzymes and for zinc-finger transcription factors, and its availability affects thymic output, lymphocyte proliferation and metallothionein expression in published models. Ascorbic acid (CAS 50-81-7, C6H8O6, 176.12 g/mol) is a water-soluble reductant and the required cofactor for dioxygenases including prolyl hydroxylases and the TET DNA demethylases. Reduced glutathione (CAS 70-18-8, C10H17N3O6S, 307.32 g/mol) is the dominant intracellular thiol buffer and the substrate of glutathione peroxidases and S-transferases.
The combination is chemically interactive by design and by consequence: ascorbate and glutathione are both reductants that participate in the same recycling network, while zinc is a redox-inert transition metal whose coordination chemistry can be influenced by thiol availability. Concentrations for each component are printed on the vial label and restated on the lot-matched Certificate of Analysis. Supplied for laboratory research use only.
Questions about Tri-Immune (Zinc · Vitamin C · Glutathione)
What is in the vial?
Three components in one 30 mL aqueous solution: zinc, ascorbic acid and reduced L-glutathione. The per-component concentration is printed on the vial label and restated on the lot-matched Certificate of Analysis, so calculations can be checked against a documented value.
Is this a peptide product?
Only in part. Glutathione is a gamma-linked tripeptide, while zinc is a trace element and ascorbic acid a water-soluble vitamin. The preparation is catalogued under vitamins and cofactors rather than with the peptide vials for that reason.
Is a COA available?
Yes. A lot-matched Certificate of Analysis is available for the batch you receive, documenting component identity and concentration. Match the lot number printed on the vial to the COA before recording any results.
Can the components be varied independently?
Not in this format — the ratio is fixed by the fill. Studies that need to titrate zinc, ascorbate or glutathione separately should use the single-component products, which are stocked individually, and use this blend only where a constant combined input is wanted.
