Esterification reactions of lipase in reverse micelles
(Wiley Subscription Services, Inc., A Wiley Company, 1990-04-05)
The activities of lipase from Candida cylindracea and Rhizopus delemar have been investigated in water/AOT/iso-octane reverse micellar media through the use of two esterification reactions: fatty acid-alcohol esterification ...
A new isolation and purification method for staphylococcal protein A using membrane encapsulated rabbit IgG-agarose
(Wiley Subscription Services, Inc., A Wiley Company, 1989-10-20)
A new isolation and purification method for bioproducts using membrane-encapsulated affinity adsorbents was investigated. The new method involves encapsulation of affinity adsorbents, batch adsorption of the bioproduct ...
Application of affinity adsorption in thienamycin fermentation
(Springer-Verlag, 1989-02)
Many antibiotic fermentations are sensitive to high concentrations of their own product possibly due to product regulation and toxicity mechanisms. In this paper we discuss the feasibility of using affinity adsorption with ...
Charge-coupled device imaging of rapid calcium transients in cultured arterial smooth muscle cells
(Elsevier, 1990)
Transient changes in the concentration of intracellular free calcium are associated with the transduction of primary signals and the subsequent employment of Ca2+ as a second messenger in a multitude of cell types. These ...
Transient measurement of dissolved oxygen using membrane electrodes
(Elsevier, 1989)
Transient mode dissolved oxygen measurement has been studied using a specially constructed galvanic membrane electrode controlled by a microcomputer. A four-layer diffusion model was developed to describe the dynamic ...
Fischer-Tropsch synthesis on bimetallic ruthenium-gold catalysts
(Elsevier, 1985-06)
The effect of Au in the behavior of Ru as a Fischer-Tropsch catalyst was studied. Two series of catalysts were investigated, one supported on SiO2 and the other on MgO. Au did not seem to alter the product distribution on ...
Monte Carlo simulations of membrane signal transduction events: Effect of receptor blockers on G-protein activation
(Kluwer Academic Publishers; Biomedical Engineering Society ; Springer Science+Business Media, 1995-05)
Cells have evolved elaborate strategies for sensing, responding to, and interacting with their environment. In many systems, interaction of cell surface receptors with extracellular ligand can activate cellular signal ...
zrp2: a novel maize gene whose mRNA accumulates in the root cortex and mature stems
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-10)
A near full-length cDNA clone (pZRP2) was isolated from a cDNA library constructed from maize root mRNAs. The predicted polypeptide has a calculated molecular mass of 66 975 Da, is largely hydrophilic, and contains 26 ...
Mixed epithelial and stromal tumor of the kidney with cervical and intestinal differentiation
(Springer-Verlag, 2005-09)
Degradation of pentachlorophenol by non-immobilized, immobilized and co-immobilized Arthrobacter cells
(Elsevier, 1991)
Non-immobilized, immobilized and co-immobilized Arthrobacter (ATCC 33790) cells were examined for their ability to degrade PCP in a mineral medium. Non-immobilized cells could completely remove PCP from the aqueous phase ...
