Different binding affinities of HMW and LMW sTnT isoforms to TnI and Tm. Solid-phase protein binding assays were used to assess the binding of sTnT isoforms with TnI and Tm. A: normalized titration curves showed that the LMW sTnT isoform has a higher binding affinity for TnI than that of the HMW sTnT isoform (P < 0.01). B: normalized titration curves further showed that the LMW sTnT isoform had a higher binding affinity to Tm than that of the HMW sTnT isoform (P < 0.002). Data are presented as means ± SD.
