What it is

TB-500 is the synthetic form of thymosin β-4, a naturally occurring 43-amino-acid peptide that binds and sequesters G-actin, regulating cytoskeletal dynamics.

It is used as a reference compound in pre-clinical research on actin dynamics, angiogenesis, and cell migration. For laboratory use only.

Reconstitution & storage

Reconstitute with bacteriostatic water — add slowly down the vial wall and swirl gently; do not shake.
Store lyophilized vials at -20°C; once reconstituted keep at 2–8°C and use within 16 weeks.
Protect from light and avoid repeated freeze–thaw cycles.
