What is the excitation/emission maxima of resorufin?
Measurement of enzyme kinetics using a continuous-flow microfluidic system.
Authors:Seong GH, Heo J, Crooks RM
Journal:Anal Chem
PubMed ID:12964765
'This paper describes a microanalytical method for determining enzyme kinetics using a continuous-flow microfluidic system. The analysis is carried out by immobilizing the enzyme on microbeads, packing the microbeads into a chip-based microreactor (volume approximately 1.0 nL), and flowing the substrate over the packed bed. Data were analyzed using the ... More
Crystallization of beta-galactosidase does not reduce the range of activity of individual molecules.
Authors:Shoemaker GK, Juers DH, Coombs JM, Matthews BW, Craig DB
Journal:Biochemistry
PubMed ID:12578385
'By use of a capillary electrophoresis-based procedure, it is possible to measure the activity of individual molecules of beta-galactosidase. Molecules from the crystallized enzyme as well as the original enzyme preparation used to grow the crystals both displayed a range of activity of 20-fold or greater. beta-Galactosidase molecules obtained from ...

Stochastic inhibitor release and binding from single-enzyme molecules.
Authors:Gorris HH, Rissin DM, Walt DR,
Journal:Proc Natl Acad Sci U S A
PubMed ID:17965235
'Inhibition kinetics of single-beta-galactosidase molecules with the slow-binding inhibitor d-galactal have been characterized by segregating individual enzyme molecules in an array of 50,000 ultra small reaction containers and observing substrate turnover changes with fluorescence microscopy. Inhibited and active states of beta-galactosidase could be clearly distinguished, and the large array size ... More
'Many areas of research today are based on enzymatic assays most of which are still performed as enzyme-linked immunosorbent assays in microtiter plates. The demand for highly parallel screening of thousands of samples eventually led to a miniaturization and automation of these assays. However, the final transfer of enzymatic assays ... More
Microchip device for performing enzyme assays.
Authors:Hadd AG, Raymond DE, Halliwell JW, Jacobson SC, Ramsey JM
Journal:Anal Chem
PubMed ID:9286159
'An automated enzyme assay was performed within a microfabricated channel network. Precise concentrations of substrate, enzyme, and inhibitor were mixed in nanoliter volumes using electrokinetic flow. Reagent dilution and mixing were controlled by regulating the applied potential at the terminus of each channel, using voltages derived from an equivalent circuit ... More
