Gel electrophoresis patterns of PD-1.5 and PD-1.9. (a) The amplified fragments of PD-1.5 were digested with Alu I: the polymerase chain reaction (PCR) product size was 333 base pairs (bp), which was digested to 264 and 69 bp. If the product was digested, the allele was identified as T; if not, it was identified as C. (b) The amplified fragments of PD-1.9 were digested with Bpu 10I: the PCR product size was 408 bp, which was digested to 260 and 145 bp. If the product was digested, the allele was identified as C; if not, it was identified as T.
