EZ-Accu Shot™ Starved Cells

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 per inoculum on R2A media.


1. Delivers 50-200 CFU per inoculum on R2A agar as required by the Japanese Pharmacopeia
2. Strains are less than or equal to three passages from reference culture,  meets USP/Ph. Eur./JP requirements
3. Instant dissolve pellet reduces preparation time
4. No dilutions required for simplified test procedure  
5. 50 tests per kit, ideal quantity for labs of any size
6. Refrigerated storage is easy and economical
7. Traceability to reference cultures ensures authenticity
8. Online Certificate of Analysis provides detailed strain information l
9. Traceability to reference cultures ensures authenticity
10. Technical Support experts available for guidance
11. Product warranty
