Product Introduction

MT-1, full name Metallothionein 1, CAS No.72126-73-7, is a fully artificial synthetic peptide intermediate manufactured by solid-phase peptide synthesis technology. Under standard temperature and pressure, it appears as uniform white or off-white crystalline powder, with a minimum purity of 99% verified by HPLC testing.

Its molecular formula is C208H342N60O65S6, molecular weight 4512.27 Da. Rich sulfhydryl groups inside the molecular structure grant it unique metal ion binding capacity, making it core experimental raw material for laboratory research covering metal ion metabolism, oxidative stress response, in-vitro cell culture and peptide biochemical mechanism analysis.

Our factory adopts standardized full-sequence synthesis procedures, strictly limiting single impurity ≤0.1% and total impurity ≤1.0%. Each finished batch is supplied with complete official COA documents, covering HPLC purity analysis, moisture measurement, heavy metal content control, organic residue inspection and microbial limit testing, fully matching raw material standards for global biological labs and chemical research institutes.

Quality Inspection & Factory Test Standard

All MT-1 synthetic peptide batches go through three full inspection phases before delivery: raw material pre-inspection, real-time intermediate monitoring, finished product comprehensive testing, to guarantee consistent stable quality for long-term repeated laboratory experiments.

Stage 1: Raw Material Pre-inspection

All amino acid monomers, resin carriers and catalytic reagents used for synthesis will complete purity, moisture and heavy metal testing before feeding. Substandard raw materials are rejected and returned to suppliers, with all test records archived for more than 5 years for full source traceability.

Stage 2: Intermediate Process Real-time Monitoring

During peptide coupling, cleavage, desalting and purification, sampling tests are performed every 2 hours to monitor reaction conversion efficiency, eliminate residual protective groups and avoid excess impurity generation from incomplete reactions. All production parameter logs are filed together with batch records.

Stage 3: Finished Product Comprehensive Full Test

After vacuum freeze-drying into crystalline powder, QC lab completes all enterprise-standard testing items: HPLC purity analysis, mass spectrometry sequence matching identification, moisture test, heavy metal limit test, organic residue detection, microbial limit inspection, solubility verification and visual appearance check.

Only batches passing all indexes will be issued a stamped official Certificate of Analysis (COA), containing batch number, production date, full test data and qualified seal, delivered together with goods to buyers. Any unqualified products are classified as waste and disposed uniformly without market circulation.

Our factory operates independent peptide synthesis and professional testing labs, equipped with full testing equipment including high-performance liquid chromatograph, mass spectrometer, ICP-MS heavy metal detector and Karl Fischer moisture titrator. All testing staff hold professional chemical analysis certifications, delivering high-precision, repeatable test data to support customer academic papers and lab research reports.

Why Choose Our Factory

Our factory has long been engaged in the customized synthesis and mass production of laboratory polypeptide intermediates such as MT-1 synthetic peptide, serving global universities, biochemical research laboratories and chemical R&D institutions. We take stable product quality and safe, smooth logistics transportation as the two core service standards, and build a complete guarantee system from production to delivery, which is the key reason why many laboratory customers choose long-term cooperation with us.

Rigorous end-to-end control to ensure consistent product quality across the board.

Quality is the core foundation of laboratory research raw materials, and we have built a closed-loop whole-process quality control system to lock product quality from raw materials to finished products.

First of all, raw material access control is strict. All Fmoc amino acid monomers, resin carriers and chromatographic raw materials used for MT-1 synthesis are purchased from qualified high-purity suppliers. Each batch of raw materials will pass purity, heavy metal and moisture testing before entering the production workshop. Unqualified raw materials will be returned unconditionally to avoid hidden dangers of impurities from the source.

Secondly, real-time monitoring of the whole production process. The synthesis, purification and freeze-drying links of MT-1 are equipped with special quality inspectors for sampling and testing every 2 hours. Once abnormal reaction parameters or impurity fluctuations are found, the production line will be adjusted immediately to ensure the consistency of each batch of peptide molecular sequence and purity.

Most importantly, finished products implement 17 full-index delivery inspections. Our self-owned testing laboratory is equipped with HPLC, mass spectrometer, ICP heavy metal detector and other complete testing equipment. Every batch of MT-1 must pass purity, moisture, microbial limit, organic residue and other full tests before leaving the factory. The internal control purity standard reaches 99.2%, and the delivery qualified standard is not lower than 99%. Each batch of goods is attached with a stamped official COA test report, and all test data is filed for more than 8 years to realize full traceability of quality.

Different from small manufacturers with loose testing standards, all our products are limited to laboratory in vitro research use, with clear usage warning labels on the outer package, and we issue standardized MSDS safety documents together with the goods, so customers can use the raw materials for experiments with complete quality data support.
