Research use only. The information below concerns laboratory reference materials for in-vitro research and makes no medical, therapeutic, diagnostic, cosmetic or performance claims.
Peptide reference materials are sold under many overlapping names, aliases and abbreviations. This glossary clarifies the terms a researcher needs to match a catalogue entry to the correct molecule.
Common names and aliases
- BPC-157 — a synthetic pentadecapeptide reference standard.
- TB-500 — commonly the N-acetylated fragment of Thymosin β4; distinct from full-length Thymosin β4.
- CJC-1295 No-DAC — also called Mod GRF (1-29); distinct from DAC-modified CJC-1295.
- Ipamorelin — a pentapeptide reference standard.
- GHK-Cu — the copper(II) complex of glycyl-L-histidyl-L-lysine; Copper Tripeptide-1 is included as an INCI cross-reference name.
- MOTS-c — a 16-amino-acid mitochondrial-derived peptide.
Fragments vs full-length
A fragment is a defined sub-sequence of a larger peptide with its own molecular formula, mass and CAS number. Confusing a fragment with the full-length molecule leads to incorrect mass and concentration calculations.
Salt forms
Reference materials are often supplied as acetate or trifluoroacetate salts. The salt form changes the total mass, so net peptide content must be used when preparing stock solutions.
