Overexpression system and biochemical profile of CTX-M-3 extended-spectrum β-lactamase expressed inEscherichia coli [PDF]

FEMS Microbiology Letters, 2004
An efficient over-expression system was developed for CTX-M-3 extended-spectrum-beta-lactamase. The recombinant enzyme was purified from 1 l of culture to yield 22 mg of pure enzyme. The N-terminal amino acid sequence was determined to be NH2-QTADVQ...

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

FlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

Incidence of two virulence factors (aerobactin and mucoid phenotype) among 190 clinical isolates ofKlebsiella pneumoniaeproducing extended-spectrum β-lactamase [PDF]

FEMS Microbiology Letters, 1992
Because outbreaks of multiple-resistant Klebsiella pneumoniae isolates producing extended-spectrum beta-lactamases were recently observed in French hospitals, the presence of virulence factors was examined for (i) phenotype by bioassay for aerobactin production and by culture for the mucoid phenotype, and (ii) genotype using intragenic probes of ...
