Zika virus lateral flow assays using reverse transcription-loop-mediated isothermal amplification.

ABSTRACT: Owing to the global spread of the Zika virus (ZIKV) infection, field-ready diagnostics are urgently warranted. In this study, we sought to detect ZIKV using reverse transcription loop-mediated isothermal amplification (RT-LAMP). Briefly, we performed and optimized ZIKV RT-LAMP for the analysis of biological samples (PBS, urine, and plasma). Based on our findings, this method could detect ZIKV RNA in 40 min at 63 °C without any off-target amplification. After performing specificity tests using BtsI restriction enzyme digestion, the feasibility of ZIKV RT-LAMP was determined via end-point detection with different sample matrices. Thereafter, a lateral flow assay (LFA) was conducted to directly detect the ZIKV RT-LAMP products. Based on the LFA reaction, hybridization occurred between
