Figure 1From: Straightforward thiol-mediated protein labelling with DTPA: Synthesis of a highly active 111In-annexin A5-DTPA tracer Binding affinity of anxA5-DTPA (6). Competition experiments demonstrate the inhibition of anxA5-FITC binding to apoptotic Jurkat T cells by active anxA5-DTPA, wildtype anxA5, and lack of inhibition by inactive M1234-anxA5-DTPA. The graph shows normalised median values of fluorescence intensity measured using flow cytometry (mean of three independent experiments ± SEM for each concentration).Back to article page
