Figure 1

Dose determination of DQB1 alleles. A. The dCT (CTGDQx - CTGDR3) for each GDQ probe was assessed in thirty-two previously typed DNA samples. Each dot represents one DNA sample identified by the indicated probe. The means of the dCT values for samples containing one- or two-copies of the identified alleles are indicated, and the differences were significant for GDQ3, 7, and 8 by a two-tailed, unpaired t test (p<0.0001). ND, there were no tested samples with two copies of a GDQ4-positive allele. An abbreviated key to the alleles identified by each probe is indicated in parentheses (see Table 2 for a complete key). B. DNA samples with a positive signal for probes GDQ3 and GDQ7 are displayed. Each line connects the dCT results for a single DNA sample for each of these two probes. Samples homozygous for DQB1*0602 are those that display two copies for both probes.
