  Abstract: Objective  To establish a rapid detection methodof human coronavirus HKU1 (HCoV-HKU1) based on loop-mediatedisothermal amplification (LAMP). Methods  With the applicationof LAMP, five sets of LAMP primers were designed. The synthesizedHCoV-HKU1 gene was used as a template, and the optimal primers wereset by real-time turbidity method. Specificity and sensitivity ofthe method were assessed. Results  Other pathogenic organismsand human genome in the method have not shown any response signal.In the experiment of sensitivity,  HCoV-HKU1 plasmid gene hada detection limit of 1 copy/?滋l in each reaction. Conclusion This study indicates that our LAMP method is a rapid,sensitive, specific method to detect pathogen of HCoV-HKU1, and hasa good application prospect in clinical differential diagnosis andcoronavirus monitoring of port.
