Overview

This catalog item is the TB-500 fragment Ac-LKKTETQ, a short synthetic peptide corresponding to an actin-binding motif within thymosin beta-4. It is used in cell-migration assays and cytoskeletal-organization models. The fragment is distinct from full-length thymosin beta-4 and should not be conflated with it. No dosing, injection, or administration guidance is provided.

Research context

Actin-binding and sequestration assays
Cell-migration in-vitro models
Cytoskeletal-organization studies
Wound-healing cell-culture models

A supplier Certificate of Analysis (COA) is a starting point. Released lots are verified by an independent U.S. laboratory:

Identity by LC-MS
HPLC purity
Peptide content
Salt composition
Endotoxin
Sterility when offered for sterile in-vitro work
Metals and water when on the panel

Certificates appear here when a lot is verified.
