An immunoassay method of the HIV-1p24 antigen by sandwich method, using at least one polyclonal antibody recognizing the HIV-1p24 antigen and at least two monoclonal antibodies recognizing the HIV-1p24 antigen, is provided together with a reagent therefor, to establish more highly sensitive assay of the HIV-1p24 antigen than conventionally.

Immunoassay method of HIV-1p24 antigen and reagent therefor

A hemoglobin sampler for use with stool samples for clinical tests and diagnoses of the digestive tract diseases in mass screening, etc. by securely sampling and collecting occult hemoglobin with water content from the stool samples without being hindered by the undigested solid content of stools. The sampler has a core member consisting of a porous fiber bundle made up of a plural number of synthetic fibers bundled in the longitudinal direction thereof, a rod of a suitable length provided with a thermosetting synthetic resin sheath at the outer periphery of the core, one end of the rod forming a sample absorbing member with a suitable surface area and small diameter made up of the above mentioned porous fiber bundle. The sampler can quantitatively sample occult hemoglobin with water from stool samples of various properties, thereby offering an easy sample method for the subject and stable specimen for tests. Thus, the utility of the test method can be fully exerted and the sampler is quite useful for clinical tests and mass health screening.
