Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
94 words
Apparatus for performing a quantitative radioimmunoassay comprising: a bead for carrying a dry antibody; a gripper for gripping said bead, said gripper comprising an elongate handle portion, and a clasp portion; a carrier for carrying said gripper, said carrier comprising a base portion a plurality of spaced apart collars carried by said base portion and for receiving therethrough said elongate handle portion; and a reaction chamber for receiving said bead when said bead is gripped by said gripper and having support means to support said carrier when said gripper is carried by said carrier.
Claim 2
Dependent Claim
94 words
Apparatus for performing a quantitative radioimmunoassay comprising: a bead for carrying a dry antibody; a gripper for gripping said bead, said gripper comprising an elongate handle portion, and a clasp portion; a carrier for carrying said gripper, said carrier comprising a base portion a plurality of spaced apart collars carried by said base portion and for receiving therethrough said elongate handle portion; and a reaction chamber for receiving said bead when said bead is gripped by said gripper and having support means to support said carrier when said gripper is carried by said carrier.
Claim 3
Dependent Claim
29 words
