| 摘要 |
A method of small volume bead-based radioimmunoassay which includes utilization of an immunoassay particle having a solid phase substrate linked to a target particle capture moiety which dissociably captures target particles in an immunoassay sample. Specifically, a bead linked to antibody which competitively dissociably captures target particles and labeled particles of an immunoassay sample in a small volume bead-based radioimmunoassay to allow determination of the concentration of target particles, the level of protease activity, or the level of protease inhibitor activity in such immunoassay samples.
