The Control Standard Endotoxin is a good alternative for expensive Reference Standard Endotoxin to construct a standard curve in kinetic assay and end-point chromogenic assay or positive control of gel clot assay. Our CSE is labeled by potency and matched to LAL reagent lots. Users do not need to do the CSE/RSE ratio assay.

1. Product information

Control Standard Endotoxin (CSE) is extracted from E.coli O111:B4. CSE is an economic alternative to Reference Standard Endotoxin (RSE) in constructing standard curves, validating product and preparing controls in LAL test. The labeled potency of CSE endotoxin E.coli standard is referenced against RSE. The Control Standard Endotoxin could be used with gel clot assay, kinetic turbidimetric assay or kinetic chromogenic assay as the endotoxin testing standards. The Certificate of Analysis will show the matched LAL reagent lots.

5-20EU/vial or 50-200EU/vial

3. Product feature and application

Our CSE was labeled by the potency and matched to LAL reagent lots. Users do not need to do the CSE/RSE ratio assay. Low potency control standard endotoxin is available to avoid lots of steps of dilution. It is low cost, convenience and easy to used.
