TB-500
The active fragment of thymosin beta-4, not the full protein. Vials labelled TB-500 sometimes contain the full-length protein or vice versa.
What we measure
- HPLC purity (%)
- Identity by LC-MS/MS
- Measured mass per vial (mg)
What tends to go wrong
Often confused with full-length thymosin beta-4.
This is a pattern we see across submitted samples, not a claim about any particular vendor. The only way to know about your vial is to test your vial.
