Physical and chemical properties of human plasma alpha2-macroglobulin.
Alpha2-M (alpha2-macroglobulin) was purified from human plasma by two different procedures. As well as having no detectable impurities by the usual criteria for testing the homogeneity of protein preparations, these alpha2M preparations showed a single component, after reduction in urea, of 185000 daltons by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. The molecular weight of the...
متن کاملalpha2-Macroglobulin on human vascular endothelium
alpha2-Macroglobulin (alpha2M) has been identified on the luminal surface of endothelial cells in sections of normal human arteries, veins, and lymphatics by the indirect immunofluorescent technique. The specificity of the immunofluorescent reaction was confirmed by immunoabsorption studies. Prior absorption of the anti-alpha2M antiserum by purified alpha2M at equivalence completely inhibited e...
متن کاملPlasmin inhibitor interactions. The effectiveness of alpha2-plasmin inhibitor in the presence of alpha2-macroglobulin
alpha2-Plasmin inhibitor and alpha2-macroglobulin were allowed to compete for the protease plasmin. The binding of the enzyme to these inhibitors was assessed by two different but comparable methods. The interactions were completed in 10 s of incubation, and transfer of plasmin from one inhibitor to the other did not occur. Almost as much plasmin was bound to alpha2-plasmin inhibitor in mixture...
متن کاملSynthesis and secretion of alpha2-macroglobulin by cultured human fibroblasts
The following observations indicate that cultured human WI-38 fibroblasts synthesize and secrete alpha2-macroglobulin into serum-free medium: (a) after incubation of cultures with [35S]L-methionine, a labeled protein appeared in the medium which was precipitated by antiserum directed against alpha2-macroglobulin; (b) after incubation of cultures with [35S]L-methionine, a major band of radioacti...
متن کاملAlpha2 Macroglobulin-Like Is Essential for Liver Development in Zebrafish
BACKGROUND Alpha 2 Macroglobulin family members have been studied extensively with respect to their roles in physiology and human disease including innate immunity and Alzheimer's disease, but little is known about a possible role in liver development loss-of-function in model systems. PRINCIPAL FINDINGS We report the isolation of the zebrafish alpha2 macroglobulin-like (A2ML) gene and its sp...
