| Abstract: | A determination of ABO blood group in bloodstain by dot-ELISA was described. The extracts of bloodstain were spotted on a nitrocellulose membrance blocked with 3％ bovin serum albumin(BSA) and followed by incubation with peroxidaselabelled monoclonal anti-A and anti-B antibody. The enzymic activity was demonstrated using the substrate 3, 3-diaminobenzidine (DAB) . A brown spot indicated the positive result. This method can detect as little as 0.005 μ1 whole blood. The entire assay could be completed within 1.5h. All of 48 bloodstains prepared were correctly typied. Compared with other routine methodes, the dot-ELISA have advantages of rapidity, simplicity and sensitivity. |
