Protein engineering of penicillinase as affinity ligands for bioprocessing
(Elsevier, 1989)
The active site and the substrate binding site of penicillinase ([beta]-lactamase) from Bacillus licheniformis were altered in this study so that the enzyme retains the specific binding capability to the [beta]-lactam ...
Validation of flow cytometric competitive binding protocols and characterization of fluorescently labeled ligands
(John Wiley & Sons, Inc., 2001-10-01)
Background Fluorescently labeled ligands and flow cytometric methods allow quantification of receptor-ligand binding. Such methods require calibration of the fluorescence of bound ligands. Moreover, binding of unlabeled ...
Application of membrane-based preferential transport to whole broth processing
(Wiley Subscription Services, Inc., A Wiley Company, 1997-08-20)
Preferential transport in adsorptive membranes can be used to selectively remove biochemicals directly from fermentation broths. During preferential transport, an adsorbing solute is selectively transported across the ...
Fe-ZSM-5 for Selective Catalytic Reduction of NO with NH3: A Comparative Study of Different Preparation Techniques
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2001-07)
Fe-ZSM-5 are prepared by using four different techniques: conventional aqueous ion-exchange (CA), improved aqueous ion-exchange (IA), solid-state ion-exchange (SS) and chemical vapor ion-exchange (CV). All of the catalysts ...
High density peptide microarrays. In situ synthesis and applications
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-09)
The technologies enabling the creation of large scale, miniaturized peptide or protein microarrays are emerging. The focuses of this review are the synthesis and applications of peptide and peptidomimetic microarrays, ...
Use of coimmobilized biological systems to degrade toxic organic compounds
(Wiley Subscription Services, Inc., A Wiley Company, 1991-07)
The concept of coimmobilizing cell mass (and/or enzyme) and adsorbent in a hydrogel matrix for biodegradation of toxic organic chemicals was introduced. Under defined experimental conditions, the coimmobilized system using ...
Current concepts of morphology of amorphous polymers-- II. Degree of local order and overall chain conformation
(Elsevier, 1979)
After a brief discussion on our earlier electron microscopyrresults of amorphous polymers and the results obtained by others in recent years from small angle neutron scattering and optical anisotropy measurements, it is ...
Noble Metal (Pt, Rh, Pd) Promoted Fe-ZSM-5 for Selective Catalytic Oxidation of Ammonia to N2 at Low Temperatures
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2002-03)
We have reported previously the excellent performance of Fe-exchanged ZSM-5 for selective catalytic oxidation (SCO) of ammonia to nitrogen at high temperatures (e.g., 400-500 °C). The present work indicates that the reaction ...
Effect of adsorbents on degradation of toxic organic compounds by coimmobilized systems
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-15)
The use of coimmobilized systems for treatment of toxic organic compounds has been proposed. The proposed approach combines the use of adsorbents and laboratory identified microorganisms immobilized in a protective permeable ...
Techniques for preparing hydrogel membrane capsules
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1988-12)
Techniques for preparing four kinds of hydrogel membrane capsules are described. In the present process the material being encapsulated remains in its original environment in an aqueous suspension. Also, capsule characteristics ...
