We are proud to offer a new test to help ensure that your products are as free of contaminants as possible. Recent inspections have indicated a need to verify the absence of glucans. The Endosafe^®-PTS™ Glucan Assay is a rapid test designed for investigational purposes to validate that your products are free of (1,3)-ß-D glucans, which are molecules that are found in the cell walls of most yeasts and molds. Glucans contaminate cell culture fluid, yeast protein production, air quality samples, and cellulose filter preparations, causing false-positive results in LAL assays and triggering OOS investigations.

Charles River's new PTS™ Glucan Assay allows you to quickly and easily quantify glucans, leading to better process monitoring and faster OOS resolutions. The Charles River glucan cartridges have a sensitivity range of 10-1,000 pg/mL, yield results in less than 30 minutes, and can be run on the same Charles River PTS™ reader that is used for endotoxin detection and Gram identification.

The PTS™ testing platform has been widely implemented globally as a cost-effective and time-saving solution for rapid testing. Other testing applications that can be performed on the PTS™ platform include Gram identification and protein concentration.
