15 described as "the parent specification". 3 and 5 are filed in the name of Murex Corporation, claiming priority from 1 and 2. Dinesh Andrew Jacob and Miles Gerald Hossom are named as the inventors. FIELD OF THE INVENTION 20 This invention relates to detection of AIDS virus. BACKGROUND OF THE INVENTION
AIDS has become a worldwide problem over a short time. The problem is only likely to increase in the foreseeable future. There is apparently no cure at 25 present, but spread of the disease could be contained, e.g. until a cure is found, by quick and accurate diagnosis of potential carriers.
A subject can usefully be tested by analysis of plasma, serum or another liquid sample, for the presence 30 of the virus. PRIOR ART A summary of the prior art is given in the parent specification. SUMMARY OF THE INVENTION 35 A device of the type fully described, claimed and illustrated in the parent specification has antibody to AIDS-causing virus immobilised on the filter material therein and is used for testing for the AIDS virus in a liquid sample.
In general terms, a filter material has antibody, e.g. monoclonal antibody, immobilised in a reaction zone thereof, the liquid sample is applied on to the reaction zone and allowed to flow through the filter material where it is taken up by absorbent material disposed in contact with the filter material. DETAILED DESCRIPTION OF THE INVENTION
The device which is preferably used in the invention comprises an aperture through which the specimen can be introduced; a filter including a reaction zone which receives liquid through the aperture, and a peripheral zone; and absorbent means associated with the peripheral zone, but not the reaction zone, of the filter. Such a device is fully described and illustrated in the parent specification.
In a process according to the invention, the specimen is introduced on to the reaction zone of the filter through the aperture, suitably by flow under gravity, and is taken up in the absorbent means/material. By having coated or impregnated the filter material with antibody in the reaction zone, antigen-antibody reaction products remain in the filter, after passage of the specimen and washing as necessary. These products can then be visualised or otherwise tested in conventional manner.
By way of example, monoclonal antibody is immobilised on latex microparticles or other particles or in the filter material. The antibody is against the AIDS-causing virus or other agent such as HTLV-III, lymphadenopathy virus or AIDS-associated retrovirus. Seru under test is then added, possibly containing HTLV, followed by globulin, e.g. human IgG, enzyme-labelled.
^ Alternatively, labelled hydridising DNA can be used to probe DNA exposed by lysis of a clinical sample on the
>1 5 substrate.
Washing is conducted as necessary, e.g. between each step as described above. Bound labelled reactant can be visualised in conventional manner, in order to determine the presence of antibody bound to antigen in the reaction 10 zone.
