Amplification refractory mutation system-PCR is essential for the detection of chimaeras with a minor allele population: a case report.

Abstract excerpt

Blood chimaera is a rare but important issue for immunohaematology laboratories. Several molecular approaches, such as ABO genotyping, human leucocyte antigen (HLA) typing and DNA short tandem repeat (STR) analysis, have been used to identify chimaerism. Unfortunately, the minor allele population can be overlooked by PCR-based methods, which preferentially amplify the major allele population. A case with AweakB...
