Abstract
This invention relates to the provision of enzyme-macromolecule conjugates by conjugation with polyfunctional reagents in the presence of organic compounds which act as conditioners. Conjugation of enzymes with antibodies in the presence of conditioner yields conjugates with increased immunological specificity. Organic polyamines of either high or low molecular weight are conditioners. Conditioners are especially useful for conjugation of polymeric and unstable enzymes such as .beta.-D-galactosidase. The high degree of immunospecificity and sensitivity achieved with conditioners yields conjugates suitable for detection and quantification of substances, such as IgE, in nanogram quantities in biological fluids with many interfering substances.
