IMPACT: PCR-based Alternative to MAP testing
Contamination of biological specimens, such as cell lines, hybridomas and tumor cells, with rodent pathogens can result in devastating outbreaks of disease in laboratory animals implanted with these materials and confounding and deleterious effects on tissue culture-based experiments.
The traditional method for testing biological specimens for murine pathogens has been the Mouse Antibody Production (MAP) test. The major disadvantage of MAP testing is the 6 to 8 weeks required to get results. To address this issue, our laboratory has developed the Infectious Microbe PCR AmplifiCation Test or IMPACT, which is a panel of PCR assays that detects murine pathogens. Comparison of IMPACT results with MAP testing results for representative DNA and RNA viruses indicated that the sensitivity of the IMPACT was equal or greater than that of MAP testing.
