[Characteristics of the serum proteins of cancer patients in an acid medium].
Under condition of nitric acid titration of aqueous and hydrochloride solutions of sera from patients with cancer certain serum proteins become insoluble at higher values of pH as compared to the other proteins of sera. The latter lose solubility at the pH values corresponding to transition to the insoluble state of serum proteins from people without malignant tumours. The results of studies in the temperature regime effect on the found peculiarities of serum proteins from patients with cancer in the acid medium permit assuming that the physical bases of the marked transitions are different. The mentioned regularity is not pronounced with a temperature rise up to 35--40 degree C.
