TB-500 (fragment)

What it is

In this catalog, TB-500 means the synthetic fragment Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln (residues 17–23 of thymosin β-4). It is not the 43-residue full-length protein. Lyophilized powder; 5 mg or 10 mg.

What research explores

• Identity and stability of the acetylated heptapeptide
• Cell-migration and cytoskeletal (actin) remodeling assays
• Preclinical angiogenesis models linked to the 17–23 domain
• Analytical distinction from full-length thymosin β-4

Studies

Much of the clinical and preclinical literature cites full-length thymosin β-4, not this fragment. Direct evidence for Ac-LKKTETQ is limited and largely preclinical / analytical. Controlled human data for the fragment are essentially absent.

Reported effects

Fragment papers describe activity in in-vitro migration and wound-closure assays; metabolites may differ from the intact peptide. Do not extrapolate full-length protein findings to this vial.

In the literature

Published fragment protocols are model-dependent; CodePept does not publish a protocol. Where literature cites full-length thymosin β-4, that does not automatically apply to this material.
