Summary for Patent: 5,231,004
Title: Use of heme-containing proteins as stabilizers for enzyme-labeled immunoreactants
Abstract:Heme-containing proteins, such as cytochrome c, are useful in admixture with enzyme-labeled immunoreactants, such as peroxidase-labeled antibodies or fragments thereof. The heme-containing proteins and enzyme-labeled immunoreactants can be supplied in a buffered composition as part of a test kit. The buffered composition comprising the heme-containing protein and peroxidase-labeled immunoreactant excludes 4\'-hydroxyacetanilide, which is a phenolic electron transfer agent. The composition can be used in immunoassays for detecting various immunologically reactive species, such as hCG, and chlamydial or gonococcal antigens.
