Petite Mutant Analysis
Petite Mutant Analysis
Petite Mutant Analysis - A test to determine the percentage of petite (respiration-deficient) cells in your yeast sample. Although healthy yeast cells always generate petites at a low frequency, a large number of petite mutant cells will considerably slow fermentation and is an indication of an unhealthy population. Samples of yeast slurry will be analyzed using a tetrazolium chloride overlay procedure to score for petite colonies.
