Figure 2. Early presence of KREC and transplant-related morbidity.

KREC signal joint (sj) copies were detected in all studied patients (#1–#10) at either 2–4 months (a) or various time lengths (b) post-bone marrow transplant (BMT). KREC copies were determined by real-time quantitative (RQ) PCR and calculated by comapring the obtained cycle threshold (Ct) for each patient to the Ct of the same patient's KREC levels before undergoing BMT, using the ΛΛCt relative quantification analysis. The percent ratios between KREC-cj copies and KREC-sj copies were measured in patients with early presentation of KRECs (#7–#10) (c). Four age-matched healthy individuals were used as controls. Each sample was detected in triplicate in all experiments.
