Title: Lina Cui: Innovator in Biochemical Probes

Introduction

Lina Cui is a prominent inventor based in Gainesville, FL (US). She has made significant contributions to the field of biochemical probes, particularly in the detection of cathepsin activity and cellular senescence. With a total of 2 patents, her work showcases innovative approaches to complex biological challenges.

Latest Patents

One of her latest patents is titled "Probe for detection of cathepsin activity." This invention presents CTLAP, a fluorogenic probe that is rapidly activated by CTL and exhibits good selectivity over CTB and CTV, which are the closest competing analytes for CTL activity probes. CTLAP is notable for its intrinsically low background fluorescence, attributed to the notably low quantum yield measured for the probe. It demonstrates markedly higher turn-on ratios (24-fold) and moderately improved enzyme selectivity (6- to 10-fold) compared to Z-FR-AMC, a commercially available CTL-selective probe. Optimum selectivity for CTL is achieved within 10 minutes of incubation with the enzyme, indicating that CTLAP is suitable for rapid detection of CTL, even in the presence of competing cathepsins.

Another significant patent is "Near infrared small molecule probes for the detection of cellular senescence." This invention comprises a biomarker-triggered moiety, a near infrared (NIR) fluorophore reporter, a self-immolative linker, and a self-immobilizing moiety for the visualization of senescent cells and methods of use thereof.
