AmplifyRP® XRT for BCTV is a rapid DNA amplification and detection platform designed for field-based or laboratory testing of Beet curly top virus in many crops including: bean, beet, hemp (Cannabis spp.), pepper, potato, spinach, and tomato. This kit includes lyophilized reaction pellets containing the necessary reagents to amplify BCTV DNA at a single operating temperature (42 °C).

AmplifyRP® XRT is a real-time isothermal nucleic acid amplification and detection system that rapidly amplifies small portions of DNA or RNA 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 ( - ). NOTE: This assay requires a fluorometer to work properly.

Prior molecular diagnostic experience is not required to perform AmplifyRP® XRT tests. Total assay time is less than 30 minutes when used with the AmpliFire® as a real-time assay.
