Molecular hydrogel-immobilized enzymes exhibit superactivity and high stability in organic solvents.
This communication describes the use of a molecular hydrogel to immobilize enzymes for catalyzing reactions in an organic solvent to attain superactivity and exceptional stability.
We describe an electrochemical oxidative desorption of benzenediazonium-grafted organic layers and immobilized proteins on the layers from indium-tin-oxide electrode surfaces.
Background and Objective: Studies showed that Aloe vera extract can influence reproductive functions in animals. The purpose of this study was to determine the effect of immobilization stress and Aloe vera extract on serum LH, FSH and testosterone levels in male rats. Materials and Methods: In this study, male Wistar rats were randomly divided into 9 groups including control, Aloe ve...
In this study, the effect of low-frequency ultrasound on the structure and activity of urease enzyme has been investigated. For this purpose, the enzyme was exposed to ultrasound with 20 kHz frequency at different time intervals. The urease enzyme was immobilized on the surface of magnetic nanoparticles (Fe2O3), and activated silica gel with 89% and 66% efficiency respectively. The enzyme activ...
The biogenous iron oxide (BIO) from Leptothrix ochracea was transformed to an organic-inorganic hybrid support to prepare an excellent immobilized enzyme showing high catalytic performance.
Curdlan production by Agrobacterium sp. IFO13140 immobilized on loofa sponge, alginate and loofa sponge with alginate was investigated. There was no statistically-significant difference in curdlan production when the microorganism was immobilized in different matrices. The loofa sponge was chosen because of its practical application and economy and because it provides a high stability through i...
This novel, competitive immunoassay simultaneously detects seven drugs of abuse in urine. A urine sample is placed in contact with lyophilized reagents, the reaction mixture is allowed to come to equilibrium (10 min), and then the whole mixture is applied to a solid phase that contains various immobilized antibodies in discrete drug-class-specific zones. After a washing step, the operator visua...
