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.
Claims14
A test pack kit for use in assaying a liquid medium for a ligand which comprises in a packaged combination:
- (a) at least two assay tubes, each tube having a cylindrical side arm which can be interconnected with the side arm of another assay tube to form a leak-proof connecting channel;
- (b) an antiserum;
- (c) a conjugate of a metal-labelling substance with said ligand;
- (d) a separation agent in vials containing material used for separating the bound antibody-metal labelling complex from the unbound metal labelling substance;
- (e) assay calibration standards-in vials containing known concentrations of unlabelled ligand, and
- (f) instrument calibration standards-in vials containing several containing several known concentrations of the metal-labelling substance.
