Thermostability studies on human complement component C3 showed that saturation of the electronegative sites in the C3 molecule with divalent cations offered some protection against heat denaturation, a finding not previously reported in the literature. To inactivate C3 in about 30 minutes, the required temperature was 61°C in the presence of excess Ca2+ions, 59.5°C in the presence of excess of Mg2+ions, but only 54°C in the absence of these ionized metal ions.
