Laboratories following Japanese Pharmacopeia (JP) guidelines know the challenges of performing Media Growth Promotion Testing on R2A agar. The JP states that R2A media should be challenged with strains that have been starved for 3 days prior to conducting the test. To simplify and accelerate test procedures for growth promotion of R2A agar, we have developed EZ-Accu Shot™ Starved Cells. These test-ready control strains have been starved prior to lyophilization and deliver the required concentration of 50-200 CFU/ml when rehydrated in 10ml.
