How to read product files
How to read a COACatalog, lot, purity, concentration and test data.
First confirm that the catalog and lot numbers match the product received. Then review specifications, concentration, purity, endotoxin, activity and other test results, followed by storage conditions and expiry. Results from different lots are not interchangeable.
Manual, SDS or COA?Choose the right file for use, safety or traceability.
The product manual explains composition, use and storage. The SDS covers hazards, protection, first aid, transport and disposal. The COA records quality and release data for a specific lot. In short: manual for use, SDS for safety and COA for lot quality.
Reconstitution and storageCommon reconstitution, aliquoting and storage practices.
Follow the product manual or COA first. Briefly centrifuge before opening, reconstitute gently with the specified solvent and volume, and avoid vigorous mixing or foaming. Aliquot by working amount and store as directed to minimize repeated freeze-thaw cycles.
Endotoxin requirementsInterpret endotoxin requirements by application.
Endotoxin is commonly reported as EU/μg, EU/mg or EU/mL and should be assessed against the product dose and assay system. Common methods include gel clot, kinetic chromogenic, kinetic turbidimetric and recombinant Factor C assays. Cell, immune, primary-cell and in-vivo work usually require tighter control.
