Introduction
Thymosin beta-4 is a 43 amino acids protein that is encoded by the TMSB4X gene. It plays a role in regulation of actin polymerization. Thymosin beta-4 binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization. It is also involved in cell proliferation, migration, and differentiation. It has been studied in a number of clinical trials.

- Incubate 1.5 h at RT or O/N at 4°C.
- Add 100 µl standard or sample to each well.
- Incubate 2.5 h at RT.
- Add 100 µl prepared streptavidin solution.
- Incubate 45 min at RT.
- Add 100 µl TMB One-Step Substrate Reagent to each well.

Storage/Stability
Standard, biotinylated peptide, and positive control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened microplate wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge.
