Purification, partial characterization, and CNBr-sepharose immobilization of a vasorelaxant glucose/mannose lectin from Canavalia virosa seeds.
A novel mannose/glucose-binding lectin from Canavalia virosa (designated as ConV) has been purified from seeds of C. virosa by affinity chromatography on a mannose-Sepharose 4B column. ConV strongly agglutinates rabbit erythrocytes and was inhibited by monosaccharides (D-mannose, D-glucose, and α-methyl-D-mannoside) and glycoproteins (ovalbumin and fetuin). SDS-PAGE revealed three bands corresp...
متن کاملPurification, partial characterization and immobilization of a mannose-specific lectin from seeds of Dioclea lasiophylla mart.
Lectin from the seeds of Dioclea lasiophylla (DlyL) was purified in a single step by affinity chromatography on a Sephadex® G-50 column. DlyL strongly agglutinated rabbit erythrocytes and was inhibited by monosaccharides (D-mannose and α-methyl-D-mannoside) and glycoproteins (ovalbumin and fetuin). Similar to other Diocleinae lectins, DlyL has three chains, α, β and γ, with mass of 25,569 ± 2, ...
متن کاملImmobilization of antibodies on alginate-chitosan beads.
An anti-hapten IgG was covalently immobilized on glutaraldehyde-activated alginate-chitosan gel beads. The antibody immobilization efficiency was influenced by glutaraldehyde-bead reaction time, IgG concentration and pH. In addition, immobilization conditions such as glutaraldehyde and antibody concentrations influenced antibody hapten binding affinity. The immobilized IgG on the beads was stab...
متن کاملImmobilization Of Catalase From Red Poppy On Chitosan Beads
Catalase enzyme from red poppy (Papaver rhoeas) plant was immobilized covalently with glutaraldehyde onto chitosan particles. The changes in the kinetic properties of the immobilized and free red poppy catalase were determined. The Km values were found to be 26 and 33 mM for free and immobilized red poppy catalase on chitosan. Furthermore, various characteristics of free and immobilized red pop...
متن کاملCrystallization and characterization of an inflammatory lectin purified from the seeds of Dioclea wilsonii.
DwL, a lectin extracted from the seeds of Dioclea wilsonii, is a metalloprotein with strong agglutinating activity against rabbit and ABO erythrocytes, inhibited by glucose and mannose. DwL was purified by affinity chromatography on a Sephadex G-50 column and ion exchange chromatography on a HiTrap SP XL column. SDS-PAGE revealed three electrophoretic bands corresponding to the α (25,634 ± 2 Da...
