Test Label: Biotin labeled primer / FAM probe
Test Format: AmplifyRP® XRT
Internal Control: Yes - Exogenous

AmplifyRP XRT for Foc TR4 is a rapid DNA amplification and detection platform designed for testing banana root, rhizome, stem, pseudostem, and leaf for Fusarium oxysporum f. sp. cubense tropical race 4 (Fusarium odoratissimum), the causal agent of Panama Disease. This kit includes lyophilized reaction pellets containing the necessary reagents to amplify Foc TR4 DNA and an exogenous DNA control at a single operating temperature (42 °C).

AmplifyRP XRT is a real-time isothermal DNA amplification and detection system that rapidly amplifies small portions of DNA and offers unrivaled detection capabilities in an easy-to-use testing format. It offers comparable sensitivity and specificity to published PCR methods while eliminating laborious and costly nucleic acid extractions.

The test can be performed virtually anywhere using the battery operated AmpliFire fluorometer. Assay parameters are loaded via barcode and results are automatically displayed as ( + ) or ( - ).

Prior molecular diagnostic experience is not required to perform AmplifyRP XRT tests.

NOTE: This assay requires a fluorometer to work properly.
