Plasmin 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 کاملAlpha2-plasmin inhibitor and alpha2-macroglobulin-plasmin complexes in plasma. Quantitation by an enzyme-linked differential antibody immunosorbent assay.
An enzyme-linked differential antibody immunosorbent assay has been developed for the quantification of alpha2-plasmin inhibitor-plasmin and alpha2-macroglobulin-plasmin complexes. In this method the inhibitor-plasmin complex is bound to a surface by an inhibitor-specific antibody, and the plasmin bound to the inhibitor is quantified by a second antibody, rabbit antiplasminogen F(ab')2, labeled...
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 کاملFactors influencing the production of kanamycin by Streptomyces canus.
The production of kanamycin by three species of Streptonbyces and four fermentation media was studied. Streptomyces canus in medium No. 2 gave the highest yields of kanamycin aftrr 72 hrs. of fermentation. The presence of both molasses and glucose in the fermentation mcdium was an important factor for the production of kanamycin. The best concentration of molasses and glucose were 15.0 and 10.0...
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...
