2.4.1. PCR Amplification of HBA1 gene fragment
PCRwas carried out in a total volume of 50 μL containing 1 U of Kapa
2G Fast DNA polymerase (Kapabiosystems, Cambridge, US), 1 × PCR
buffer, 1.5 mM MgCl2, 200 μM of each dNTP, 0.25 μM of each 5′-TGGA
GGGTGGAGACGTCCTG-3′ (forward) and 5′-CTGGCACGTTTGCTGAGG
GAA-3′ (reverse) primer, 7.5% DMSO and 100 ng of genomic DNA. The
PCR conditions were as follows: initial denaturation at 95 °C for 2 min,
followed by 35 cycles of 95 °C for 30 s, 60 °C for 30 s, 72 °C for 30 s
and final extension at 72 °C for 2 min. PCR and primer extension reactions
were carried out in the TaKaRa Dice Gradient thermal cycler
(Otsu, Shiga, Japan).
