Antibodies to delta sleep-inducing peptide in ultralow doses: study of the effect by enzyme immunoassay.

The effects of potentiated homeopathic preparations containing antibodies to delta sleep-inducing peptide in ultralow doses were studied by enzyme immunoassay. Experiments were performed with the following immunochemical reagents: antigens of delta sleep-inducing peptide conjugated to various macromolecular carriers and specific antigens. Antibodies to delta sleep-inducing peptide were synthesized in dilutions of C3, C6, C12, C50, and C200. Enzyme immunoassay showed that test preparations of antibodies in dilutions of 1:400-1:3200 produce the combined effect on immune complex formation. The proposed method holds much promise for identification of medicinal preparations in ultralow doses.
