Glucans are known to cause false positive results in LAL assays, therefore triggering investigations. Our Endosafe®-PTS™ glucan assay allows you to quickly and easily quantify these glucans, leading to better process monitoring and faster out-of-specification (OOS) resolutions.
The Endosafe®-PTS™ glucan assay is a rapid, in-process test designed for investigational purposes to validate that your yeast-derived products are clear of (1,3)-β-D glucans. The disposable glucan cartridges the system uses have a sensitivity range of 10-1,000 pg/ml, yield results in less than 30 minutes, and can be run on the same portable instrument that is used for PTS™ endotoxin detection or PTS™ Gram ID.
This product offering is in addition to the glucan-specific buffer that we offer for those compounds that are known in advance to have a strong possibility of being contaminated by glucans.
