【Abstract】 A simple and rapid method for HLA-DRB gene typing is discussed in this paper.After isolating DNAs from recipient and donors, the PCR with DRB primers were carried out.The partial products of patient and donors can be mixed for DNA crossmatching.The products were, then, analysed on 12% polyacrylamide gel elect-rophoresis.The fingerprinting of seven unrelated individuals were showed in different pattern.In four cases of patient-donor pairs, the two pairs gave matched pattern and the other pairs gave mismatched one.The results could be compared with HLA serologic typing, MLC and PCR-SSO DQA typing.This method would be useful to screen unrelated donor for BMT.更多还原
