The hydration of actin.
The hydration of actin was studied by differential scanning calorimetry between -30 degrees C and 30 degrees C and by thermogravimetric analysis. The differential scanning calorimetry provided the freezable water content of G- and F-actin as a function of concentration, and the thermogravimetric analysis measured the total water content. The difference between the two yielded the nonfreezable water content (bound water) as a function of concentration. The nonfreezable water content of G-actin was higher than the F-actin over the whole concentration range from 1-40% actin.
