[Immunochemical study of the CBA mouse kidney].

Immunoelectrophoresis and agar precipitation reaction allowed one to reveal 7 antigens in CBA mouse kidney. One of them, with a relative electrophoretic mobility--0.35, is specific for the kidney. The remaining renal antigens are common to the kidney and other organs and tissues of mice. The antigens with mobility in the albumin and alpha-globulin zones proved to be serum ones. An antigen with a mobility approximating 0 is specific for the kidney and liver. An antigen with a mobility in the alpha 2-globulin zone does not seem likely to be homogeneous and, apart from broad inter-organ specificity, bears the greatest resemblance to the lungs antigen.
