What is TB-500 Frag 17-23?
TB-500 Frag 17-23 is a short synthetic peptide corresponding to residues 17-23 of Thymosin Beta-4 (sequence LKKTETQ), the region studied for its role in actin binding. It is a distinct compound from full-length TB-500, supplied for researchers studying this specific fragment in isolation.
- A 7-amino-acid fragment (LKKTETQ) covering positions 17-23 of Thymosin Beta-4
- Distinct compound from full-length TB-500 (43 amino acids, CAS 885340-08-9)
- Studied for its relationship to the actin-binding motif of the parent peptide
- Supplied separately for research isolating this specific active region
For research use only. Not approved for human therapeutic use.
TB-500 Frag 17-23 is a short synthetic peptide fragment corresponding to residues 17-23 of Thymosin Beta-4 (sequence Leu-Lys-Lys-Thr-Glu-Thr-Gln / LKKTETQ), the region containing the actin-binding motif studied in the parent molecule. It is a distinct compound from full-length TB-500 (43 amino acids, CAS 885340-08-9), supplied separately for researchers studying this specific active region in isolation.
TB-500 Frag 17-23 is manufactured in an ISO9001 certified laboratory to a guaranteed purity of ≥98%. Every batch is independently tested using HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature controlled, monitored cold storage system to preserve compound integrity throughout the supply chain. Certificates of Analysis are available on request.
Sold strictly for in vitro research purposes only. Not for human consumption. Intended for use by qualified researchers in laboratory settings only.
