Description
Technical field
The invention belongs to antibody production techniques fields, and in particular to a kind of rabbit-anti grouper serum immune globulin HRP mark
Remember the preparation method and application of antibody.
Background technique
Grouper is the high-quality fish of top grade in current marine fish.With China's Artificial Rearing of Epinephelus coioides
Mature and Epinephelus coioides seed industrialization large-scale production, becomes important marine fish culture kind.But it is sick in recent years
Evil takes place frequently, and causes huge economic loss to the aquaculture industry of grouper.
Virus, helminth and bacterium infection are very harmful to prelarva and juvenile fish, cause to marine fish culture industry huge
Loss.
Currently, generalling use PCR method detection lithosporic fish virus, helminth and bacterium infection, PCR method is by detecting fish body
The expression of viral gene in brain and eyes, Lai Jianding disease infect;However, parent population is as nursery in the nursery of grouper
Main body, it is impossible to by parent population kill detected again by PCR method;Therefore, a kind of basis for guaranteeing fish body normal vitality is needed
On, the method that detects disease.
