Research Background

About TB-500 5mg

What it is

TB-500 is a synthetic peptide fragment derived from thymosin beta-4. It is supplied as a lyophilized powder, 5 mg per vial, intended strictly for laboratory research use.

Research areas

Thymosin beta-4 and related peptide fragments have been examined in preclinical models of tendon and muscle injury. Laboratory research has also investigated its role in cell migration and actin regulation within in vitro models. Cardiovascular research has explored thymosin beta-4 in models of angiogenesis.

Storage & handling

TB-500 should be stored frozen and protected from light in its original lyophilized form until use. Repeated temperature cycling of the sealed vial should be minimized to preserve compound stability.

Research context

The name 'TB-500' functions as a commercial designation rather than a formal biochemical name; published research literature more often refers to the parent protein, thymosin beta-4, or its defined active fragment, when reporting sequence and assay data. This naming distinction is a common point of clarification in peptide research discussions. Thymosin beta-4 remains a well-characterized actin-binding peptide in cell-biology research literature.

All compounds are supplied for in-vitro laboratory research and identification purposes only. Not for human or animal use.

Frequently Asked Questions

Our compounds are tested by an independent third-party laboratory, and we publish the certificate for each one in our COA library. COAs are available on request and show HPLC and mass spectrometry data.

Each COA includes: compound identity confirmation, purity percentage via HPLC, mass spectrometry verification, batch number, and testing date. All testing is performed by an independent third-party laboratory. For research purposes only.

Lyophilized (freeze-dried) peptides should be stored at -20°C and kept away from light and moisture for maximum stability. Once reconstituted, store at 4°C and use within 30 days. All compounds are shipped with appropriate packaging to maintain integrity during transit. For laboratory research use only.

Orders placed by 4PM ET are dispatched the same day, seven days a week. Every order ships from the US with tracked shipping, and your tracking number is emailed the day it ships. Most domestic orders arrive within 2–5 business days.

No. All compounds sold by Core Research Peptides are strictly for in-vitro laboratory research purposes only. They are not intended for human or animal consumption, diagnostic use, or therapeutic application.
