title: [Stability of serum immunoglobulin conformation in various tumors].
abstract: As shown by means of temperature-perturbation differential spectrophotometry blood serum immunoglobulins G from patients with gastric cancer and with some other tumors were more resistant to 2 M urea as compared with the immunoglobulins from healthy volunteers and patients with gastric ulcerous disease. The resistance of IgG conformation was altered in the course of gastric cancer treatment.
