Abstract
A test pack kit for assaying for a ligand in a liquid medium. The kit comprises specially designed assay tubes, each tube having a cylindrical side arm which can be interconnected with the side arm of another assay tube. In addition, the pack kit contains antiserum; a conjugate of a metal labelling substance with the ligand; assay calibration standards--in vials containing known concentrations of unlabelled ligand; a separation agent in vials containing material used for separating the bound antibody--metal labelling complex from the unbound metal labelling substance and instrument calibration standards--in vials containing several known concentrations of the metal--labelling substance. Errors caused by pipetting or transferring of reagents from one container to another are practically eliminated.
