Isolation and immunological characterization of human glomerular basement membrane antigens.
Normal human glomerular basement membrane (H-GBM) was solubilized by collagenase and subjected to crossed immunoelectrophoresis with rabbit antibodies against H-GBM. Seven precipitates appeared with the mobility of alpha, beta, and gamma globulins. Only two of these precipitates might be specific for GBM, since the other precipitates disappeared after absorption of the antiserum with liver and ...
متن کاملImmunoreactive Basement Membrane Antigens in Normal Human Urine and Serum
Using a sheep antiserum to human glomerular basement membrane (GBM), studies of urine from healthy adults showed the presence of two cross-reactive antigens. These antigens were purified partially by preparative electrophoresis and electrofocusing, and separated on G-200; both appeared to be acidic, of high molecular weight, and carbohydrate rich. Their immunologic relationship to human GBM sol...
متن کاملBovine Glomerular Basement Membrane
The collagenous domain of bovine glomerular basement membrane was excised in soluble form by limited pepsin digestion and characterized. The domain amounts to approximately 25% of the whole membrane by weight. The constituent polypeptides were studied using several electrophoresis systems and amino acid analysis. The electrophoresis systems used were a combination of agarose and polyacrylamide...
متن کاملGlomerular Basement Membrane
The noncollagenous domain hexamer of collagen IV from bovine glomerular basement membrane was further investigated to determine the types of collagen chain from which subunits M2*b and M3 are derived. M2*b was shown to be a shorter form, containing 9 fewer residues, of M2*a which was previously established as the noncollagenous domain of a third chain, a3, of collagen IV (Saus, J., Wieslander, ...
متن کاملThe immunohistopathology of glomerular antigens. The glomerular basement membrane, collagen, and actomyosin antigens in normal and diseased kidneys.
The immunofluorescent localization of antisera to human glomerular basement membrane (GBM), collagen, and smooth muscle actomyosin was examined in 15 specimens of normal renal tissue and 98 specimens from patients with renal disease. The anti-GBM and anticollagen antisera normally localize to GBM, while antiactomyosin localizes to the mesangium. Diabetic nephropathy revealed a striking expansio...
