PCT No. PCT/GB89/00568 Sec. 371 Date Mar. 6, 1990 Sec. 102(e) Date Mar. 6, 1990 PCT Filed May 23, 1989 PCT Pub. No. WO89/11655 PCT Pub. Date Nov. 30, 1989.The present invention relates to assay techniques for detection of ligands in solution and to means for putting such techniques into effect. In particular it relates to an improved assay technique which provides a liquid calibrator for use in standard assays in circumstances where the ligand itself is rare, expensive, or difficult to prepare in a sufficiently pure or quantifiable form. |
