Table 2 50% Inhibitory concentration of cadmium on the 111In-labelling of DTPA-exendin-3

From: Improved labelling of DTPA- and DOTA-conjugated peptides and antibodies with 111In in HEPES and MES buffer

Buffer 50% inhibitory concentration of Cd2+ (nM)a
NaAc 0.011 (0.007 to 0.019)
NH4Ac 0.013 (0.010 to 0.019)
MES 2.5 (1.5 to 4.1)
HEPES 2.7 (2.2 to 3.3)
  1. aCadmium concentrations that lead to a 50% reduction in the labelling efficiency of DTPA-exendin-3 in 0.1 M NaAc, NH4Ac, MES and HEPES. The 95% confidence interval is indicated in parentheses.
