Isolation of a heparan sulfate-containing proteoglycan from basement membrane.
We have isolated a unique, basement membrane proteoglycan from the Engelbreth-Holm-Swarm (EHS) sarcoma. This proteoglycan, estimated to be 0.75 X 10(6) daltons, was found to contain about equal amounts of protein and covalently linked heparan sulfate. Antibody prepared against this proteoglycan reacts with the basement membrane matrix in the tumor and with the basement membranes in skin, kidney...
متن کاملCharacterization of heparan sulfate-proteoglycan of glomerular basement membranes.
Native and de novo synthesized heparan sulfate-proteoglycan (HS-PG) of basement membranes from isolated whole glomeruli were characterized. Sepharose CL-6B chromatograms of [35S]sulfate-labeled de novo synthesized HS-PG extracted from whole glomeruli indicated identical molecular weight characteristics to that isolated from purified basement membranes (Mr of intact HS-PG approximately equal to ...
متن کاملIsolation 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 کاملPurification and characterization of heparan sulphate proteoglycan from bovine brain.
A heparan sulphate proteoglycan was purified from adult bovine brain tissues and its structure was characterized. The major heparan sulphate proteoglycan from whole bovine brain had a molecular mass of >200 kDa on denaturing SDS/PAGE and a core protein size of 66 kDa following the removal of glycosaminoglycan chains. Fractionation on DEAE-Sephacel showed that this proteoglycan consisted of thre...
متن کاملIdentification of a new membrane-bound heparan sulphate proteoglycan.
The morphological changes that occur during intestinal development have been extensively described, but the molecular basis of these changes is largely unknown. As a result of our efforts to identify molecules that play a role in intestinal morphogenesis during development, we have previously isolated a cDNA that is developmentally regulated in the intestine. This cDNA, named OCI-5, was recentl...
