Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...

background: cystic echinococcosis caused by the metacestode of echinococcus granulosus is a major problem in both humans and domestic animals health. there-fore, a standardized and approachable diagnostic tool (rapid tests) for the serodiag-nosis of cystic echinococcosis (ce) is still needed. methods: in the present work, antigen b labeled with gold nanoparticles was used to detect antibodies a...

Both human integrin receptors Mac-1 (CD11b/CD18,CR3)and lymphocyte function-associated antigen (LFA)-1 (CD11a/CD18) have been demonstrated to bind human intercellular adhesion molecule-1 (ICAM-1) (CD54). Here we show that LFA-1 and Mac-1 can bind to ICAM-1 in the mouse as well. Interestingly, we observed that binding of murine LFA-1 dominates over Mac-1 for binding to ICAM-1. Using three differ...

in this study which has been carried out from 1996 until 1997 soluble latex agglutination antigen was prepared from L, donovani,sudan(s-1) by culturing in special media,harvesting,and later solubilizing by freezing and thawing.the antigen were futher prepared by high speed centrifugation.after measurement of the protein (lowry method) concentration of the antigen was set at 2.2 mg/ml,the antige...
