ABSTRACT
<p><b>OBJECTIVE</b>To apply the single cell nested multiplex polymerase chain reaction (PCR) to HLA typing, and analyze the influence factors on the amplification results.</p><p><b>METHODS</b>Single cell DNA templates were prepared with different methods. The exon 2, 3 and intron 2 of HLA-A, B, and exon 2 of DRBI were amplified using multiplex PCR. The second round of SSP-PCR HLA typing was carried out according to the large scale routine HLA typing results.</p><p><b>RESULTS</b>Enzyme lysis method was the most efficient procedure for preparing the single cell DNA template, with a success rate (SR) of 93.3%, while the SRs of alkali lysis and freezing-thaw lysis methods were 83.3% and 73.3%, respectively. The second round amplification using enzyme lysis and SSP-PCR in 20 samples obtained a 95% success rate and a 15% allele drop out rate. The time for performing the whole procedure was less than 6 hours.</p><p><b>CONCLUSION</b>The modified nested multiplex PCR technique is efficient for single cell HLA typing and might be applied to clinical preimplantation genetic diagnosis.</p>
