The Research Sample Repository contains approximately 2.9 million sample aliquots from more than 60,000 first allogeneic related and unrelated transplant recipient/donor (or cord blood) pairs with complete, validated clinical outcome data from the CIBMTR Observational Database. The majority of the paired samples have complete high-resolution data available for HLA-A, B, C, DRB1/3/4/5, DQ and DP loci.
Sample Types
Samples in the Research Sample Repository are stored as:
- Whole blood
- Cryopreserved whole blood
- Plasma
- Blood spotted on filter paper
- Peripheral blood mononuclear cells (PBMC) viable and non-viable
- B-Lymphoblastoid cell lines (B-LCL) viable and non-viable
- Granulocytes
- Serum
- DNA
- Whole genome amplified DNA
Available sample types vary by sample source and year of collection. Sample sources include: adult and pediatric related/unrelated donors, cord blood and transplant recipients. Samples from recipients are drawn before the patient’s conditioning regimen begins. Prior to January 1, 2000, 100-day post-transplant samples were also drawn.
