Analog chromatography with glomerular basement membrane isolated from normal and nephrotic rabbits was performed to see if there was a molecular sieving effect by the basement membrane. In a normal glomerular basement membrane column, 125I-labeled human serum globulin and 131I-labeled human serum albumin were eluted at the same position, probably at the void volume of the column. However, 125I-labeled insulin and tritiated water appeared with a delay and gave separated peaks. In nephrotic glomerular basement membrane, 125I-labeled human globulin, 131I-labeled serum albumin, 125I-labeled insulin and tritiated water gave four distinctly separated peaks in that order. By analogy with Sephadex, the sieving effect of glomerular basement membrane was demonstrated. © 1976.
