Chymotrypsin is a serine protease enzyme derived from bovine pancreas, with an activity level of 3000 USP units per milligram as stated in the source. It cleaves peptide bonds adjacent to aromatic amino acids, primarily tyrosine, tryptophan, and phenylalanine. This enzyme is supplied as a lyophilized powder with a white to off-white appearance and is stable under dry, cool conditions.
The enzyme is produced using purification processes typical for pharmaceutical-grade chymotrypsin, with purity assessed by SDS-PAGE and specific activity measured via spectrophotometric assay using N-succinyl-Ala-Ala-Pro-Phe p-nitroanilide as substrate. Standard impurities include trypsin, which must be below 0.5% by activity, and moisture content under 5%. These are industry-accepted thresholds for enzymatic integrity in research and formulation use.
Chymotrypsin is purchased by pharmaceutical manufacturers for protein digestion in drug synthesis, by biotech labs for proteomics workflows, and by diagnostic kit developers for sample preparation. Bulk supply is available in 100g, 500g, and 1kg sealed HDPE containers with desiccant. Packaging complies with IATA standards for biological substances. Trade terms include FOB Qingdao and CIF destination ports, with MOQ negotiable based on volume and frequency.

Sourcing Chymotrypsin from Weifang Huajin International Trading Co., Ltd - China Import Guide
Before ordering chymotrypsin from Weifang Huajin, verify the batch-specific Certificate of Analysis includes specific activity, moisture content, trypsin contamination level, and purity by SDS-PAGE. Request the assay method used and confirm it follows USP or EP standards. Do not accept generic statements of 'high purity' without numerical data. Ensure the supplier can provide traceability to the original bovine source and manufacturing batch.
Confirm the Incoterms offered - FOB Qingdao is common - and whether the price includes export documentation and customs clearance. Lead time is typically 10 to 20 days after order confirmation, but this varies with production scheduling. Payment terms are usually T/T in advance or L/C at sight. Ask for a proforma invoice detailing weight, packaging, and HS code for accurate import duty calculation.
Upon receipt, inspect packaging for moisture damage and verify temperature control during transit. Conduct a quick activity test using a standard substrate to confirm potency matches the CoA. Retain a sample for independent third-party testing if used in regulated applications. Request the supplier's export documentation including health certificate, non-GMO declaration, and transport compliance papers for customs clearance in your country.
