Journal ArticleDOI
Luminescent bacterial sensor for cadmium and lead.
TL;DR: A sensor plasmid was constructed by inserting the regulation unit from the cadA determinant of plasmids pI258 to control the expression of firefly luciferase, capable of replicating in Gram-positive and Gram-negative bacteria.
Journal ArticleDOI
Activation of the zymogen form of prostate-specific antigen by human glandular kallikrein 2.
TL;DR: Results indicate that hK2 is responsible for the activation of proPSA, a finding that may be very important for understanding of the role of these two kallikreins in the reproductive system and in prostate cancer biology.
Journal ArticleDOI
Reporter genes lucFF, luxCDABE, gfp, and dsred have different characteristics in whole-cell bacterial sensors
TL;DR: Luciferases are better reporters in whole-cell sensor bacteria and fluorescent proteins, GFP and DsRed, gave responses at higher analyte concentrations and after significantly longer incubation times.
Journal ArticleDOI
A Luminescence-Based Mercury Biosensor
TL;DR: A new biosensor for the determination of bioavailable mercury is presented, which utilizes firefly luciferase gene as a reporter under the control of the mercury-inducible mer promoter from transposon Tn21 and Escherichia coli MC1061 as a host organism.
Journal ArticleDOI
Measurement of bacterial adhesion-in vitro evaluation of different methods.
TL;DR: Different commonly used methods to measure adhesion of bacteria; radioactive labelling, fluorescence tagging, and staining of bacteria are compared and it is shown that the best reproducibility and sensitivity were obtained using radioactive laboratoryelling.
