Salt-free or not
Thymosin α1 is quoted both ways and the mass differs accordingly. Pick one and put it on the purchase order — the code will follow it through to the COA.

Thymic peptides and antimicrobial sequences studied in immune-modulation and barrier models — with the salt form and the endotoxin status stated.
Overview
Thymic and antimicrobial.
Thymosin α1, Thymalin, LL-37 and KPV, plus the thymic peptides used in T-cell and innate-immunity research. Thymosin α1 is the most requested item here, and the one where the salt form causes the most confusion.
LL-37 is a cathelicidin fragment: antimicrobial at low concentrations and cytotoxic to mammalian cells at higher ones in vitro, which is why the working concentration matters at least as much as the purity. KPV is a tripeptide fragment of α-MSH, usually chosen because it is small enough to survive formulation.
- Thymosin α1 with and without salt, as separate codes
- Endotoxin testing by LAL on request, for cell-based work
- KPV supplied as the acetate
- Lyophilised in amber vials, shipped with desiccant

Specification
What to specify.
Three things decide whether two quotations for the “same” peptide are actually the same material.
Endotoxin, not just purity
For anything that touches cells, the LAL result is often the more informative number than HPLC purity. It is not in the standard release set, so ask.
Working concentration
LL-37 has a narrow window between antimicrobial activity and cytotoxicity in vitro. We supply the material and the specification; the concentration is your protocol's decision.
