Used in biopharmaceutical quality control to detect residual yeast DNA contamination in final products derived from Saccharomyces cerevisiae expression systems. Ensures product safety by verifying that DNA levels are within regulatory limits, particularly in recombinant proteins and vaccines. The kit supports compliance with guidelines from agencies like the FDA and EMA, helping prevent potential immunogenic or oncogenic risks associated with host cell DNA. Commonly applied during purification process validation and lot release testing in manufacturing environments.
