A new data T-cell cancer study has been added to the iReceptor Public Archive (IPA) repository, bringing the total number of annotated sequences that can be searched to over 700 million. The study, performed by Wang et. al., entitled "The Different T-cell Receptor Repertoires in Breast Cancer Tumors, Draining Lymph Nodes, and Adjacent Tissues" is the largest single study in the iReceptor Public Archive at over 310 million annotated sequences.
