At present, PCR or quantitative PCR method is commonly used at home and abroad to detect carp herpes virus type Ⅱ. There is latent infection of herpes virus. Fish with healthy appearance may carry the virus. PCR method can detect the virus nucleic acid, but it cannot confirm whether there are infectious virus particles in the fish. , so it is necessary to establish an immunological method for the detection of viral proteins

Abstract
The invention relates to a cyprinid herpesvirus II type sandwich ELISA detection kit. The kit mainly comprises a cyprinid herpesvirus II type ORF90 purified monoclonal antibody solution, an enzyme-labeled ORF90 polyclonal body solution, a diluent, a TMB substrate solution, a stop solution, cyprinid herpesvirus II type positive control, negative control, coating liquid and a 96-pore enzyme-labeled plate. The invention also relates to a detection method. The kit and the method, provided by the invention, can be applied to detection of latent infected fish virus without clinical symptom and can further be applied to research on the change rule of the cyprinid herpesvirus II type in the fish body, so that basis is provided for prevention and control of the virus. The method provided by the invention does not have specific reaction with other common viruses of crucian and goldfish, and can be applied to diagnosis of epidemic disease in domestic farms as well as exit and entry fish quarantine.
Description
technical field [0001] The invention relates to a detection kit, in particular to a carp herpesvirus type II sandwich ELISA detection kit, and also relates to a detection method using the detection kit. Background technique [0002] In recent years, Cyprinid herpesvirus Ⅱ (English name: Cyprinid herpesvirus Ⅱ, abbreviated as CyHV-2) has brought great harm to the crucian carp and goldfish aquaculture industry in my country. The morbidity and mortality are extremely high when the disease breaks out. According to incomplete statistics In 2006, the economic loss caused by the disease was as high as 718 million yuan. [0003] In the prior art, the most intuitive method for its diagnosis is to conduct histological examination on diseased fish tissues and then observe herpes virus particles by electron microscope for confirmation. At present, PCR or quantitative PCR method is commonly used at home and abroad to detect carp herpes virus type Ⅱ. There is latent infection of herpes vi...
