Chymotrypsin
Zhejiang Duadi Group Co., Ltd supplies Chymotrypsin enzyme that belongs to the serine protease family and is derived from bovine or porcine pancreatic tissue. The product is delivered as a lyophilized powder and the supplier highlights a high purity level together with specific activity expressed in USP or NF units per milligram. Originating from Hangzhou in Zhejiang Province, China, the enzyme is intended for bulk laboratory and industrial use.
In the biochemical market serine proteases such as Chymotrypsin are core reagents for protein digestion, peptide synthesis and large‑scale hydrolysis of protein feeds. Typical activity values for commercial grades lie between 2000 and 2500 USP U / mg and the powder is normally stored at - 20 °C to preserve activity. Standard packaging formats include sealed polyethylene bags ranging from 10 g to 100 g, which align with the bulk supply model described by the supplier.
Researchers, pharmaceutical manufacturers and biotech firms commonly import this enzyme for proteomics studies, drug development and enzyme‑based processing lines. The supplier advertises bulk supply options and mentions FOB or CIF shipping terms, allowing buyers to arrange freight according to their preferences. Because the listing does not state a fixed minimum order, interested parties should confirm the exact MOQ and lead‑time directly with the company.

Sourcing Chymotrypsin from Zhejiang Duadi Group Co., Ltd - China Import Guide
Before placing an order, verify the supplier’s harbour tier status, request a current certificate of analysis and confirm that the enzyme batch matches the specified activity and purity. It is also prudent to ask for a sample, if possible, to run a pilot digestion in your own laboratory before committing to bulk purchase.
Logistics should be clarified early: ask whether the shipment will be under FOB or CIF terms, confirm the preferred Incoterm, and obtain the estimated lead‑time for production and dispatch. Payment conditions are not disclosed in the listing, so discuss acceptable methods such as T/T, L/C or escrow with the supplier to align with your risk tolerance.
Upon arrival, perform a visual inspection of the sealed bags, check the moisture content and verify the expiry date. Request the original COA, ISO certification and any required safety data sheets. Conduct a functional assay to confirm activity before integrating the enzyme into large‑scale processes.
