Kinectics of Donor-specific Anti-HLA Antibody After HLA-incompatible Allogeneic Haematopoietic Stem Cell Transplantation

"Detection methods~1. . Morphology: using microscope to observe the morphology of bone marrow.~2. . Immunophenotyping: using multi-color flow cytometry (MFC) to detect immunophenotype of leukemia cells and leukemia-associated immunophenotype of bone marrow samples.~3. . Cytogenetics analysis: G-band and/or fluorescence in situ hybridization (FISH) analysis are used in this study~4. . Molecular detection: Real-time quantitative RT-PCR (RQ-PCR) and/or next generation sequencing techniques are used to detect the molecular marker, such as: PML/RARA, AML-ETO, BCR/ABL, and WT1.~5. . HLA-Typing: HLA-A, -B, -C, -DRB1, -DQB1, and -DPB1 alleles were determined according to the literatures published by our group \[Huo MR, et al. Bone Marrow Transplant. 2018;53(5):600-608\]..~6. . Other analyses: Detection of minimal residual diseases were performed using MFC and RQ-PCR according to the methods reported by our group \[Li SQ, et al. Blood,2022;140(5):516-520\]."
