ABSTRACT
Objective To establish an acurate and convenient method to distinguish human platelet antigen(HPA) SNPs based on Target Enriched Multiplex-PCR(TEM-PCR),fluorescent probe melting curve analysis and blood direct PCR.Methods Design TEM-PCR primers and probes of HPA1-17,Cab alleles,amplify target sequences of all 18 alleles by blood direct PCR and distinguish different SNPs by melting curve of probes.Results The TEM-PCR could amplify all target sequences of 18 alleles and the melting curve analysis could distinguish those SNPs,the accuracy was equal to PCR-SSP method and the process was more convenient without blood genomic DNA extraction and subsequent gel electrophoresis thus decrease the cross-contamination risk.Conclusion Successfully established a HPA1-17,Cab alleles distinguishing method based on TEM-PCR,blood direct PCR and fluorescent probe melting curve analysis technique.
