b a ckground: the role of lectins is important in interaction between pathogens and mosquito vectors. this study was performed to identify agglutinin activities of protein molecules on the midgut of culex pipiens . m e t hods: c u lex pipiens was reared in insectray condition and the midguts of males and females (blood fed and un- fed) were dissected separately in tris-hcl buffer. the extracts ...

The aim of this study was to investigate the hemagglutination properties of caprine herpesvirus-1(CpHV-1) and their application for CpHV-1 antigen detection and evaluation of the dynamics of postinfectious/vaccine antibody production. CpHV-1 hemagglutination activity was proved only with mouseerythrocytes, PBS and saline solutions at 4°C and 22°C. In vaccinated animals, goats and bucks withresp...

Monoclonal antibodies (MAbs) against the rubella virion were used to locate epitopes involved in hemagglutination and neutralization. The MAbs exhibiting high-level hemagglutination-inhibiting activity were shown by Western blot analysis to be specific for the E1 polypeptide; this is consistent with the presence of the hemagglutinin on the E1 polypeptide. Some of the E1-specific MAbs also neutr...

Forty-five strains of Campylobacter pylori isolated from gastric biopsy specimens showed distinct hemagglutination activity. The activity was partially decreased by treatment with heat, trypsin, or an alkylating agent and was inhibited by porcine gastric mucin but not by various compounds, including D-mannose.

From Mycobacterium tuberculosis, a serologically specific polysaccharide was purified. It contained mannose, arabinose, and a trace of glucose. It was not active in hemagglutination (HA) reaction. Partial acylation of the polysaccharide was carried out with palmitoylchloride, and the synthetic lipopolysaccharide contained 15.1 per cent of esterified palmitic acid. The synthetic lipopolysacchari...

The immunomodulatory proteins present in garlic have recently been shown to be identical to the garlic lectins ASA I and ASA II [Clement F, Pramod SN, Venkatesh YP. Int. Immunopharmacol. 2010; 10: 316-324]. In this study, the stability of garlic lectins as a function of pH, temperature and denaturants has been examined in relation to biological activity (hemagglutination and hagocytosis). Stabi...
