Janus emulsion assays that rely on carbohydrate-lectin binding for the detection of Escherichia coli bacteria are described. Surfactants containing mannose are self-assembled at the surface of Janus droplets to produce particles with lectin binding sites. Janus droplets orient in a vertical direction as a result of the difference in densities between the hydrocarbon and fluorocarbon solvents. B...

In this study, we fabricated PCL-nanoparticles by encapsulating dual drugs as amphotericin B and doxorubicin via double-emulsion solvent evaporation method also incorporated with ligand-lectin for targeting the infested macrophage cells and prove importance against VL. Different independent processing parameters were assessed systematically to enhance the incorporation of the dual agents with d...

iranian castor bean lectin was isolated and purified by several column chromatography methods. then, the sugar and amino acid content of the purified lectin was identified. castor bean lectin has some anti tumor and anti leukemia action. thus it may be used commercially for medical and biochemical purposes.

A previously undescribed bovine serum lectin (designated CL-43) was identified by its Ca(2+)-dependent binding to mannan and by its molecular mass of 43 kDa under reducing conditions on SDS-PAGE. The lectin was isolated by polyethylene glycol precipitation, affinity chromatography on mannan-Sepharose (followed by elution with EDTA), and absorption on Sepharose-4B-coupled rabbit anti-bovine Ig (...

We report a glycoanalysis method in which lectins are used to probe the glycans of therapeutic glycoproteins that are adsorbed on gold nanoparticles. A model mannose-presenting glycoprotein, ribonuclease B (RNase B), and the therapeutic monoclonal antibody (mAb) rituximab, were found to adsorb spontaneously and non-specifically to bare gold nanoparticles such that glycans were accessible for le...

We designed an amebiasis subunit vaccine that is constructed by using four peptide epitopes of the galactose-inhibitable lectin heavy subunit that were recognized by intestinal secretory immunoglobulin A (IgA) antibodies from immune human subjects. These epitopes are contained in the region encompassing amino acids 758 to 1134 of the lectin heavy subunit, designated LC3. Baboons (Papio anubis) ...

In this prospective study, among 47 clinically suspected cases of Liver abscess, 46 were diagnosed as of Amoebic origin. Confirmation of Amoebic Liver abscess (ALA) was done by ribosomal RNA (rRNA) gene detection from Liver abscess pus using real-time Polymerase Chain Reaction (PCR). In addition, microscopy for detection of the parasite in Liver abscess pus, and Lectin antigen as well as anti-L...
