TB-500 Fragment 17-23 is the central heptapeptide fragment containing TB4’s actin-binding domain. Third-party tested, USA-made, 99% purity peptide. Research use only (RUO).
Product Description
TB-500 Fragment 17-23 (Leu-Lys-Lys-Thr-Glu-Thr-Gln) encompasses thymosin β4’s core actin-binding region for specialized research. Laboratory studies examine direct actin sequestration, polymerization inhibition, and cytoskeletal dynamics in vitro. Research applications include cell migration mechanism analysis, wound healing pathway investigations, and angiogenesis factor studies.
This fragment allows researchers to isolate actin-binding functions from other TB4 activities. Studies investigate G-actin sequestration kinetics, cellular remodeling processes, and tissue repair signaling. Research protocols utilize Fragment 17-23 for structure-activity relationship studies, minimal functional domain identification, and comparative peptide biology research in controlled laboratory environments.
