Figure 2.

Mass spectrum showing presence of αβ dimers and $\alpha {\beta }_{\text{apo}}^{\text{ox}}$ dimer species at 28 °C (left). Relative abundance curves of each dimer species as a function of soluition temperature (right). Mean midpoint T_m and T_f values from three replicate analyses are shown indicated by colored arrows. Relative abundance values are normalized to the total abundance of HbA signal at each temperature.
