Precision Peptide Purification
We specialize in the isolation and purification of GLP-1 and GIP receptor agonists. Our Reverse-Phase HPLC (RP-HPLC) platforms are optimized to remove closely related impurities, truncated sequences, and trifluoroacetate (TFA) counter-ions, ensuring a final product that exceeds 99% purity specifications.
Key Service Features:
All purification and post-purification processing—including lyophilization (freeze-drying) and primary packaging—take place within our ISO Class 5 (Class 100) clean room suites.
Our Quality Control (QC) laboratory utilizes ultra-high-performance liquid chromatography (UHPLC) and Mass Spectrometry (LC-MS) to verify:
By integrating high-throughput HPLC purification with a robust GMP quality management system, we reduce lead times and optimize the cost of goods for your Tirzepatide API production. Our technical expertise in peptide chemistry ensures that even the most challenging hydrophobic profiles are managed with precision.
