TB-500
CAS: 885340-08-9
Research Use Only
All products are intended solely for laboratory research and are not for human or animal consumption. By purchasing, the buyer agrees to use these products in compliance with all applicable laws.
TB-500 Overview
TB-500 is a synthetic peptide analog developed for preclinical research investigation. Published studies have examined its actin-sequestering properties and interactions with structural cellular proteins in in vitro assay models. Pepticore supplies this compound exclusively as a laboratory reference material. No biological outcomes or suitability for human use is implied or established.
TB-500 History
Thymosin Beta-4 was first identified during thymus tissue studies in the 1960s. TB-500 was subsequently developed as a synthetic fragment to enable focused investigation of actin-binding peptide interactions in laboratory settings. Peer-reviewed preclinical research has since examined its structural binding properties across multiple in vitro assay formats.

Frequently asked questions
Products from Pepticore do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service.
Each vial contains exactly what’s shown on the label. For example, a 10mg vial has exactly 10mg of lyophilized peptide. Researchers can divide it into smaller portions—like four 2.5mg measurements—but the total amount remains 10mg.
Peptides are supplied as lyophilized powder. They do not come reconstituted, and any extra supplies must be sourced separately for research applications.
In lyophilized powder form, peptides stay stable for up to 2 years. After reconstitution, it should be refrigerated and is generally stable for up to 2 months.
