TB-500 is a thymosin β4–related research designation. This guide covers how to verify identity on the CoA, typical molecular reference points, and laboratory handling.
TB-500: Quick facts for laboratory documentation
| Research designation | TB-500 (Thymosin Beta-4–related research material) |
| Literature context | Associated with thymosin β4 research; confirm exact identity on your CoA |
| Full-length Tβ4 (reference) | 43 amino acids; approx. 4,963 Da when referring to intact thymosin β4 |
| Supply form | Lyophilised powder (verify mass on vial label) |
| Intended use | Scientific research only |
What is TB-500 in a research catalogue?
In research chemical catalogues, “TB-500” is commonly used as a trade-style name for thymosin β4–related research material. Full-length thymosin β4 is a 43-amino-acid polypeptide (approximately 4,963 Da). Some marketed “TB-500” lots instead refer to shorter synthetic fragments — so the batch CoA and vial label are the authoritative identity, not informal online summaries.
At My UK Peptides, TB-500 is supplied as a lyophilised powder for research use only. It is not intended for human or veterinary use, and should be handled in a properly equipped laboratory setting.
Molecular notes for lab records
Thymosin β4 research literature frequently discusses actin-binding motifs (including sequences such as LKKTET). If your protocol depends on a specific sequence length or modification, confirm those fields on the CoA before logging the material into inventory.
Supply form and sealed storage
TB-500 arrives lyophilised in sealed glass vials. This freeze-dried form is suitable for transit, but should be stored cold and dry on receipt for longer holding. Keep vials sealed until required by your institutional protocol. Protect from excess light and humidity, and allow sealed cold vials to warm before opening to reduce condensation.
My UK Peptides does not publish mixing or reconstitution instructions. Any laboratory preparation must follow your own institutional SOP and applicable regulations.
Important: TB-500 from My UK Peptides is a research compound only. It is not for human or animal use. This article does not describe clinical effects, dosing, or preparation methods.
