Fig. 4From: Evaluation of single domain antibodies as nuclear tracers for imaging of the immune checkpoint receptor human lymphocyte activation gene-3 in cancerExpression of huLAG-3 and its binding by selected sdAbs on lentivirally engineered TC-1 cells. A Representative flow cytometry results, showing staining of TC-1 cells (black line) or TC-1-huLAG-3 cells (blue line) with an antibody specific for huLAG-3. B The MFI of TC-1 cells was used to determine the fold increase in MFI when these sdAbs bound to TC-1-huLAG-3 cells (n = 2)Back to article page
