https://www.selleckchem.com/products/Sunitinib-Malate-(Sutent).html Hematopoietic stem cell transplantation (HSCT) is a curative treatment for most hematologic diseases. To evaluate the level of donor engraftment, chimerism must be carefully monitored after HSCT. Short tandem repeats, quantitative PCR (qPCR), and, more recently, digital PCR (dPCR) are widely used to determine the proportions of donor and recipient cells after HSCT. The screening and quantification of chimerism have been evaluated by 2 new methods a ready-to-use next-generation sequencing (NGS)-based method using the Devyser ChimerismNGS kit and an original combination of the Stilla crystal digital PCR (cdPCR) platform with 3-color multiplexing capacity using GenDX KMRtrack reagents. The genotyping of 4 HSCT pairs by cdPCR using 11 triplex mixes of the GenDX KMRtype kit was consistent at 98.8% with qPCR. Informative samples (n = 20) from 6 donor-recipient pairs and 1 external proficiency test demonstrated the reliability of the results (0.1% to 50%) for the 2 methods. The methods are also highly sensitive (0.1%) and accurate. The chimerism values of the 2 methods are correlated and concordant with those of the reference methods. In addition, the ADVYSER software (Devyser) is user-friendly and well adapted to chimerism monitoring. In conclusion, these 2 innovative methods are easy to perform and user-friendly in all molecular, hematology, and immunogenetic laboratories and allow the genotyping and monitoring of chimerism with high performance and sensitivity. Autologous hematopoietic cell transplantation (AHCT) is a standard of care for several subtypes of high-risk lymphoma, but durable remissions are not achieved in the majority of patients. Intensified conditioning using CD45-targeted antibody-radionuclide conjugate (ARC) preceding AHCT may improve outcomes in lymphoma by permitting the delivery of curative doses of radiation to disease sites while minimizing toxicity.
