Addition of Fillers to Sodium Alginate Solution Improves Stability and Immobilization Capacity of the Resulting Calcium Alginate Beads
Background: Although advantages of immobilization of cells through entrapment in calcium alginate gel beads have already been demonstrated, nevertheless, instability of the beads and the mass transfer limitations remain as the major challenges.Objective: The objective of the present study was to increase the stability, porosity (reduce mass transfer limit...
متن کاملImmobilization of Alkaline Protease produced from Bacillus Licheniformis PTCC1331 on Calcium Alginate (Its effect on enzymatic activity)
Alkaline Protease enzyme produced from Bacillus Licheniformis PTCC1331 in optimum Condition(Temperature 37 ?C, 150 rpm, PH=10), is immobilized in different concentrations of Sodium Alginate using entrapment method, to increase its thermal resistance in detergents, and its activity is measured thereafter. Maximum enzymatic activity of 46 was obtained in 2%w/v Sodium alginate solution. Investiga...
متن کاملImmobilization and Culturing of Mammalian Cells with Bio- Compatible Electrodeposition of Calcium Alginate Gel in Microfluidic Devices
This paper reports a unique approach to immobilize mammalian cell populations (mouse myeloma NS0) through in situ gelation of calcium alginate triggered by an electrical signal under physiologically relevant conditions. This is the first experimental observation to evaluate the electrically triggered assembly of calcium alginate gel for entrapping and culturing mammalian cells. Subsequent cell ...
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 کاملSwelling/deswelling mechanism of calcium alginate gel in aqueous solutions.
To elucidate the mechanism of dimensional changes in alginate impression in solutions, the relationship between the ion concentrations in three types of solutions (nonelectrolyte and monovalent and divalent metallic salts) and change in gel volume was examined. The gel in the monovalent metallic salt solution expanded and a decrease in monovalent cation and an increase in Ca2+ were observed. Th...
