The assay is not really liable to Fake positives because of beta-glucans, which come from cellulose as well as other plant-based mostly products and solutions, given that the BETs are.
The concluded solution release specification needs to be deemed when deciding in-method limits for every phase of manufacturing tested. For needs of assessing the relative chance of merchandise contamination, quantitative testing may very well be preferable to Restrict testing to aid products quality trending and also to determine and correct excursions before they exceed the specification and trigger solution failure. An endotoxins limit needs to be justified on a scenario-by-circumstance basis, and can be evaluated as being a Element of Every single pertinent marketing application or supplement.
