The Research Sample Repository contains approximately 3 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 CIBMTR's 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.
Samples in the Research Sample Repository are stored as:
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.
*Pair counts include incomplete multi-cord pairs with recipient and at least one cord sample available.
