Abstract

The invention provides primers, a probe, a kit and a detection method for type II nucleic acid quantitative detection of herpes simplex virusherpes simplex virus. The primers are as shown in the sequences of SEQ ID NO: 1 and SEQ ID NO: 2; the probe is as shown in the sequence of SEQ ID NO: 4, and a reporter fluorescent group and a non-quenching fluorescent group are marked at the two ends of the probe, respectively; the kit comprises the primers and the probe. The primers, the probe and the kit thereof are low in fluorescent background value, high in signal-to-noise ratio and high in detection sensitivity when used for detecting type II nucleic acid quantitation of the herpes simplex virus.

Description

technical field [0001] The present invention relates to in vitro diagnostic reagents. In particular, it relates to a primer and probe, a kit and a detection method for the quantitative detection of herpes simplex virus type II nucleic acid. Background technique [0002] Herpes simplex virus Ⅱ (herpes simplex virus Ⅱ, HSV Ⅱ) is one of the common pathogens in human viral diseases. Herpes simplex virus type II (HSV II) detection methods have a series of problems, eg. Although herpes simplex virus is easy to carry out in vitro cell culture and can produce visible cell lesions, the detection value of virus isolation and culture is low due to high technical requirements, long separation time, easy pollution, expensive equipment, and skilled technicians. Not conducive to large-scale development. Conventional PCR detection of HSVⅡ-DNA is simple and fast. However, since the amplified product needs to be detected by electrophoresis, it is easy to cause false positive results due t...
