Duffy antigen genotyping (SNP -33T>C in GATA box, DARC gene) by melting curve analysis. a Chromatogram of the Caucasian Duffy-positive phenotype (-33TT genotype), reference sample. b Chromatogram of the Cameroonian Duffy-negative phenotype (-33CC genotype), reference sample. c Melting curve analysis of the two reference samples: melting temperatures of 60.5 and 64.5 °C for Duffy-positive (Caucasian) and Duffy-negative (Cameroonian), respectively. d Melting curve analysis of a representative group of samples, including the two reference samples. Two heterozygous samples (thick red and blue lines) are also shown. Negative controls are in the lower part of the melting curves of c, d
