Development of immunoglobulin variable heavy chain gene consensus probes with conjugated 3′ minor groove binder groups for monitoring minimal residual disease in childhood acute lymphoblastic leukaemia

Table 2

Results of the RQ-PCR assays using an MGB probe and a non-MGB probe in 18 patients with ALL

Patient Normalised values of PCR target detected by MGB probe* (those by non-MGB probe)
Initial diagnosis 15 days 1 month 3 months 4 months
ALL, acute lymphoblastic leukaemia; blank, not determined; MGB, minor groove binder; RQ-PCR, real time quantitative polymerase chain reaction; –, not detected.
*The normalised values of targets were expressed as the ratio of the target copy number for each 105 cell equivalent from the integrated standard curves of human β actin, as described previously.4
