These images show the results of testing of an antibody-fluorophore conjugate prepared using pClick, developed at Rice University. The conjugate was demonstrated by visualizing antigens on breast cancer cell surfaces. A set of varied cells were incubated with a green fluorophore conjugate and stained with a red fluorescent membrane-staining dye and a blue fluorescent nuclear stain. The fluorescent imaging shows that cell surface-associated green fluorescence was exhibited only by breast cancer cells with the specific antigen. (Credit: Xiao Lab/Rice University)
