Product Information

Basic Product Information
1. TB‑500, also known as Thymosin Beta‑4 Fragment, CAS No.885340-08-9, is a synthetic acetylated heptapeptide with amino acid sequence Ac-LKKTETQ.
  
  It is manufactured by solid phase peptide synthesis (SPPS) and further purified by reversed-phase high-performance liquid chromatography (RP-HPLC). The finished product appears as white to off-white lyophilized powder. The material owns favorable water solubility and stable physicochemical characteristics with strictly controlled moisture and trifluoroacetic acid residues.
  
  Our TB‑500 belongs to research-grade biochemical raw material. Each batch undergoes HPLC purity testing and LC-MS structural identification to guarantee sequence accuracy and stable quality between batches. This product is supplied for laboratory biochemical experiments, peptide-related mechanism research and preliminary exploratory studies.
  
  We provide bulk lyophilized powder and support customized vial packaging. Documents including COA, HPLC chromatogram and mass spectrum report can be offered upon request.
  
  Important Disclaimer
  
  This product is FOR LABORATORY SCIENTIFIC RESEARCH ONLY. Not applicable for human administration, veterinary usage, clinical trials, food, cosmetic or pharmaceutical raw materials. Buyers shall comply independently with local chemical import and supervision regulations.

Introduction to Peptide Manufacturing Factory

Our peptide manufacturing factory is a professional, standardized and intelligent production base dedicated to the research, development and mass production of high-purity custom peptides and standard peptides. Adhering to strict pharmaceutical and biochemical production standards, we integrate independent R&D, precision production, rigorous quality testing and customized technical services, committing to providing high-quality peptide products and reliable solutions for global customers.

Equipped with advanced fully automated peptide synthesis production lines, purification systems and freeze-drying equipment, the factory supports multi-scale production ranging from milligram-level laboratory samples to kilogram-level industrial mass production. We cover mainstream synthesis technologies such as solid-phase peptide synthesis and liquid-phase peptide synthesis, and can efficiently customize various complex peptides, including long-chain peptides, cyclic peptides, modified peptides, fluorescent-labeled peptides and phosphorylated peptides. Our product portfolio widely serves biopharmaceutical research, cosmetic raw material development, food additive production, academic scientific research, diagnostic reagent preparation and other fields.

Quality control is the core of our production management. The factory has built a complete quality management system in line with ISO international standards, with independent professional testing laboratories. We adopt high-performance liquid chromatography (HPLC), mass spectrometry (MS), infrared spectroscopy and other precision testing methods to strictly monitor raw material screening, synthesis reaction, purification treatment, finished product packaging and every production link. This ensures that all peptide products feature high purity, stable properties, accurate molecular weight and low impurity content, meeting the differentiated quality requirements of scientific research experiments and industrial production.
