<p>Apparatus (20) for the collection of antigen, including an allergen, such as dust-mite allergen, dispersed in a motile fluid in a given environment can be inserted in one section of a pipe (21) of a standard vacuum cleaner hose. The apparatus (20) includes a receptacle (22), the body (25) of which is formed of a nylon mesh, typically with a pore size in the range 15-60 νm, and which is coated with antibody which retains the antigen coming into contact therewith. The apparatus (20) is provided with a removable holder (26) which assists in locating the apparatus (20) in the pipe (21) of the vacuum cleaner. The apparatus (20) is directly usable in an immunoassay for confirming the presence of, or quantifying, the antigen.</p> |
