[Prior Art] In the summer of 1990, the fish iridovirus, which was first confirmed at the red sea bream farm in Ehime Prefecture, subsequently spread the infection area to various regions in Shikoku and Kyushu, and also to the hamachi, striped horse mackerel and red sea bream farms. However, the infection has come to be recognized. Since the damage caused by this iridovirus is characterized by mass mortality, the spread of this virus is fatal to the aquaculture site, and its epidemics law is strongly desired. However,
Up to now, no effective quarantine law including a treatment method has been found, and it is important to detect the virus early before the outbreak of the disease and eliminate the infected fish out of the system. In addition, although the infection route of this virus is currently unknown, if there is a possibility of vertical infection, it is necessary to detect the virus early in the seedling production stage and produce virus-free seedlings. .

The monoclonal antibody of the present invention is produced by culturing a hybridoma obtained by fusing mammalian immune cells immunized with fish iridovirus as an immunogen and mammalian myeloma cells to produce the monoclonal antibody. Obtained by collecting the monoclonal antibody. The above-mentioned mammalian immune cells are prepared by immunizing mammals by a conventional method using fish iridovirus as an immunizing antigen. The mammal used here is not particularly limited, but is preferably selected in consideration of compatibility with myeloma cells used for cell fusion, and generally, mouse, rat and the like are used. The immunization method is also carried out by a general method, for example, a fish iridovirus is diluted to an appropriate concentration with a buffer solution such as phosphate buffered saline (PBS), made into a suspension with Freund's adjuvant, and subcutaneously injected. Administer to animals. Booster immunization is performed 2 to 5 weeks after the initial immunization, and this is repeated 2 to several times. As the immune cells, it is preferable to use lymphocytes taken out from splenocytes extracted about 3 days after the final immunization. Further, a cell line known as a myeloma cell (myeloma cell) as the other parent cell fused with the immune cell obtained as described above, for example, NS-O, NS-1, SP-2 derived from mouse / O,
P3-U1, FO, S194, etc. and rat-derived R210, etc. may be mentioned.

The fusion reaction between the immune cells and myeloma cells is basically a known method, for example, the method of Oi and Herzenberg (Selected Methods in Cellular Immunology, 351).
-371, WH Freeman & Co., USA press, 1980) and the like. More specifically, the fusion reaction is performed in an ordinary nutrient medium in the presence of, for example, a fusion promoter. As the fusion promoter, a commonly used one such as polyethylene glycol (PEG) or Sendai virus (HVJ) is used, and an auxiliary agent such as dimethyl sulfoxide (DMSO) is added to further enhance the fusion efficiency. It can also be used. The use ratio of immune cells to myeloma cells is the same as in the usual method, and for example, immune cells may be used at a ratio of about 1 to 10 times that of myeloma cells. Examples of the medium at the time of fusion include RPMI-1640 medium, MEM medium, E-RDF medium, and other various ordinary mediums used for cell culture of this kind, which are used for the growth of the myeloma cell line. It is possible to use, and it is usually preferable to remove a blood supplement such as fetal calf serum (FCS). The fusion is performed by thoroughly mixing a predetermined amount of the immune cells and myeloma cells in the medium,
PEG solution heated to ℃, for example, average molecular weight 1,000 ~ 6,00
It is carried out by adding about 0 to a medium at a concentration of about 30 to 60% (w / v) and mixing.

EXAMPLES Next, the present invention will be described in more detail by way of examples, but the present invention is not limited thereto. Example 1 Preparation of Monoclonal Antibody-Producing Hybridoma Against Fish Iridovirus Spleen tissue was removed from the fish iridvirus-infected striped horse mackerel obtained from Amami fish, homogenized with PBS, and then passed through a 0.45 μm filter. A spleen extract containing fish iridovirus was thus obtained. This extract was mixed with Freund's complete adjuvant (manufactured by Difco),
5-week-old male BALB so that the protein content is 100 μg
It was injected intraperitoneally into the / c mouse. After that, booster immunization was performed every two weeks with the same amount of extract, and booster immunization was performed until the antibody titer in blood was sufficiently increased. The increase in the anti-fish iridvirus antibody titer was determined by using the fish iridvirus-infected striped horse mackerel spleen extract as an antigen, and the fish ylide virus-uninfected striped horse mackerel spleen extract as a control, each having a protein concentration of 3.0 μg / ml in a 96-well microtiter plate. Coated with
An ELISA was performed and confirmed by the significant difference from the control (Fig. 1).

The monoclonal antibody (30 μg / ml) produced by 9) reacted only with the spleen extract of red sea bream infected with fish iridovirus, and did not react with the spleen extract of red sea bream uninfected with fish iridovirus (for example, HSM- in FIG. 2). The results for 803 and HSM-807 are shown). This suggests that these monoclonal antibodies can be widely used not only for striped horse mackerel but also for diagnosis of fish iridovirus infection in other fish species.
