SLAMF7
SLAM family member 7 is a protein that in humans is encoded by the SLAMF7 gene.
The surface antigen CD319 is a robust marker of normal plasma cells and malignant plasma cells in multiple myeloma. In contrast to CD138, CD319/SLAMF7 is much more stable and allows robust isolation of malignant plasma cells from delayed or even cryopreserved samples.
Elotuzumab is an antibody that targets this protein.
