SOLID SUPPORT AND ASSEMBLY FOR QUANTITATIVE AND QUALITATIVE CHARACTERIZATION OF ANTIGENS

摘要

2122126 9308474 PCTABS00021 A use of a solid support is described which comprises a polymeric material and has at least one activated portion, which has been provided by increasing its exposed surface area, in an immunoassay method for assaying an antigen in a sample. There is also provided an assembly for immunoassays comprising a solid support in the form of a stick having at least one of said activated portion and a panel capable of sliding on the stick and having at least another of said activated portion. The activated portion of the solid support leads to excellent binding characteristics for an antigen to be assayed, thus effecting outstanding immunoassay performance for the quantitative and qualitative characterization of antigens. Samples from the blood as well as secretions and discharges are well suited for the immunoassay. For example, HIV antigens present in the human saliva are readily detected by the support or the assembly disclosed.
