Description

DESCRIPTION

TB-500 Frag 17-23 is a synthetic heptapeptide corresponding to the actin-binding domain (residues 17–23, sequence LKKTETQ) of Thymosin Beta-4. In laboratory models this short fragment is studied for its proposed interaction with monomeric G-actin and its potential role in modulating actin polymerization and cytoskeletal sequestration dynamics. It is supplied as a lyophilized research compound for in vitro and preclinical investigation of actin-binding motifs and peptide–protein interaction chemistry. This material is intended strictly for laboratory research purposes and is not a drug, supplement, or article for human or veterinary use.

RESEARCH AREAS

Actin monomer (G-actin) binding and the LKKTETQ recognition motif
Modulation of actin filament polymerization and depolymerization kinetics in vitro
Cytoskeletal sequestration and remodeling pathways in cultured cell models
