title: [Aggregation of human immunoglobulins under normal conditions and in malignant stomach tumor].
abstract: We apply the thermal perturbation difference spectroscopy to demonstrate that immunoglobulins G (IgG) isolated from blood serum of a patient with stomach cancer are more stable to the influence of 12% urea than IgG of a healthy donor. IgG at the same pathology have greater tendency to aggregation than IgG at norm according to the laser correlation spectroscopy data.
