Summary for Patent: 4,735,898
Title: | Monoclonal antibodies and method of identifying species using the same |
Abstract: | The new method an products recognize human serum albumin, differentiating blood and tissue from human sources from blood and tissue of other animals. The method and products are particularly useful in forensic investigations. First, mice are injected with purified human serum albumin, spleen cells from the mice are fused with cells from a murine myeloma. Resulting hyberdomas are screened on human serum albumin coated plates. Subcloning, stabilizing by culture and continued assays for anti-human albumin activity produces products which recognize and differentiate blood or tissue samples from samples of other species. |

Application Number: | 06/755,564 |
Patent Claims: | 1. Hybrid cell line ATCC No. 8860 secreting monoclonal antibodies specifically reactive with human serum albumin.
2. Monoclonal antibodies secreted by the hybrid cell line of claim 1. 3. A method of identification of species of origin of blood, bloodstain, or tissue sample comprising contacting a sample containing albumin with anti-albumin monoclonal antibodies specific to a particular species and sensing reactivity of the monoclonal antibody with the albumin from the sample. 4. The method of claim 3 wherein the albumin is from the human species and wherein the contacting comprises contacting the albumin with human anti-albumin. 5. The method of claim 4 further comprising the preliminary steps of preparing the sample by isolating albumin from the sample. 6. The method of claim 4 comprising placing the monoclonal antibodies on a plate means and adding the sample to the substrate. 7. The method of claim 5 further comprising placing the albumin from the sample on the plate means and adding the monoclonal antibodies to the substrate. 8. The method of claim 4 wherein the sensing reactivity comprises sensing absorption readings which indicate specificity of the monoclonal antibodies for human albumin. 9. A forensic kit for identification of human species of blood, bloodstain, or tissue samples comprising human anti-albumin monoclonal antibodies, plate means for containing the monoclonal antibodies with albumin from a sample, enzyme and substrate for indicating the reactivity of the monoclonal antibodies with albumin from the sample. 10. The method of claim 3 wherein the monoclonal antibody is ATCC No. HB 8860. 11. The kit of claim 9 wherein the monoclonal antibody is ATCC No. HB 8860. |
