The binding capacity of serum immunoglobulins with amino acids in systemic lupus erythematosus

: The content of G, M, A, serum immunoglobulins and binding capacity with amino acids prolin, oxyprolin, alanin and serin was examined in 40 patients with systemic lupus erythematosus (grade I and II activity). It was established that the degree of increase of the binding capacity of Ig with amino acids was higher than that of corresponding Ig and depended on the activity of the process.
