Precision Standards for Peptide Research
American Top Lab is an analytical biotechnology provider specializing in ultra-pure peptide reagents. Every single vial is cataloged, verified for mass integrity, and searchable on our open analytical authentication network.
Certified Analytical Purity
Synthesized via Solid Phase Peptide Synthesis (SPPS) with rigorous multi-column purification ensuring absence of truncated sequences and heavy metal contaminants.
HPLC & Mass Spec Validated
We do not rely on standard internal claims. Each production batch undergoes independent High-Performance Liquid Chromatography and Electrospray Ionization Mass Spectrometry.
Direct Batch Traceability
Every vial and carton is equipped with a digital batch signature and dual-layer scratch-off PIN. Research teams can instantly verify serialization and COA logs.
Peptides Research Portfolio
Ultra-pure laboratory reference standards synthesized via SPPS with RP-HPLC and mass spectrometry certification.
TB-500 (Ac-LKKTETQ)
Target: Actin Regulation & Cell Migration
TB-500 is a synthetic fraction of the naturally occurring actin-sequestering protein Thymosin Beta-4. It binds to monomeric G-actin, regulating cellular structural cytoskeleton re-organization and promoting rapid endothelial cell migration.
