Figure 2From: DNA extraction from long-term stored urine DNA from urine and DNA from buffycoat from three patients. The agarose gel shows CTLA-4 +49 polymorphism signals from these three patients. Patient 1 with buffycoat DNA on 1 and urine DNA on 2 (GG); patient 2 with buffycoat DNA on 3 and urine DNA on 4 (AA); patient 3 with buffycoat DNA on 5 and urine DNA on 6 (AA). DNA from urine and DNA from buffycoat yield similar signals in varying magnitude.Back to article page
