Rapid statistical discrimination of fluorescence images of T cell receptors on immobilizing surfaces with different coating conditions

Abstract The spatial organization of T cell receptors (TCRs) correlates with membrane-associated signal amplification, dispersion, and regulation during T cell activation. Despite its potential clinical importance, quantitative analysis of the spatial arrangement of TCRs from standard fluorescence i...
