Title:	High fluorescence specific immune enhancing factor and methods of use for same
Abstract:	The present invention relates to a malondialdehyde-acetaldehyde adduct which acts as a specific immune-enhancing factor. In addition to its highly specific and immunogenic properties, the factor is highly fluorescent. It has an excitation frequency of about 398 nanometers and an absorbance of about 460 nanometers. The factor is also highly reactive and is also adducted to antigens including complex proteins, lipids, carbohydrates or DNA.

Application Number:	08/849,024
Patent Claims:	1. A specific immune-enhancing factor comprising: a malondialdehyde-acetaldehyde adduct having the following formula: ##STR4## wherein X is an antigen containing an amino group; N is the nitrogen atom from said amino group; and R is selected from the group consisting of a lower C.sub.1 to C.sub.6 alkyl group, benzyl, and hydrogen. 2. The factor according to claim 1 wherein R is methyl. 3. The factor according to claim 1 wherein said antigen is selected from the group consisting of a carbohydrate, a DNA molecule, a protein, a peptide, and a lipid. 4. The factor of claim 1 wherein said antigen is of an animal origin. 5. The factor of claim 1 wherein said antigen is of an environmental origin. 6. The factor according to claim 1 which has an excitation frequency of about 398 nanometers and an absorbance of about 460 nanometers. 7. The factor of claim 1 wherein said antigen is of human origin. 8. The factor according to claim 1 wherein the antigen is selected from the group consisting of bovine serum albumin, human interferon, hemoglobin and human serum albumin. 9. A method for stimulating the immunogenicity of an antigen-comprising: contacting said antigen with malondialdehyde and acetaldehyde so that a malondialdehyde acetaldehyde adduct is formed, and introducing said malondialdehyde acetaldehyde adduct to the immune system of an animal. 10. The method of claim 9 wherein said antigen is introduced for vaccination purposes. 11. The method of claim 9 wherein said malondialdehyde acetaldehyde adduct stimulates the animal's immune system to produce antibodies to the antigen. 12. A method of claim 11 further including a method of detecting antigen/antibody complexes formed by the animal in response to the introduction of the adduct to the immune system of the animal. 13. The method of claim 12 wherein said detecting is by fluorescence detection. 14. The method of claim 9 wherein said malondialdehyde acetaldehyde adduct has the following formula: ##STR5## the formula wherein X is an antigen containing an amino group, N is the nitrogen atom in said amino group, and R is selected from the group consisting of a C.sub.1 to C.sub.6 alkyl group, benzyl, and hydrogen. 15. A malondialdehyde acetaldehyde adduct formed by the process of: contacting an antigen with malondialdehyde and acetaldehyde so that an adduct is formed. 16. The adduct of claim 15 wherein said adduct has the following formula: ##STR6## Wherein R is a C.sub.1 to C.sub.6 alkyl group, H, or Benzyl and X is a peptide or protein present in a biological sample, and further providing that N is a nitrogen atom from an amino group in the peptide or protein.
