SANTA FE, N.M., Dec. 10 /PRNewswire/ -- QTL Biosystems, LLC, a provider of innovative products for bio-detection, drug discovery, and life science research, announced today the release of the QTL LIGHTSPEED(TM) Caspase-3 Assay Kit. This assay utilizes a proprietary fluorescent polyelectrolyte- based super-quenching polymer that offers a significant advantage compared to conventional small molecule fluorescence. The QTL LIGHTSPEED platform provides single-step, instantaneous, homogenous assays, and addresses a broad spectrum of drug targets in high-throughput screening.
QTL Biosystems product applies its novel QTL LIGHTSPEED platform to Caspase-3 research. Caspase-3 is part of the Apoptosis (programmed cell death) intracellular process. Apoptosis can play a significant role in disease when it is either excessive or insufficient. Because of their roles in inflammation and apoptosis, the caspases have received enormous research interest. The QTL LIGHTSPEED Caspase-3 assay combines high sensitivity with high speed for screening of potential inhibitors against Caspase-3.
"The QTL LIGHTSPEED Caspase-3 Assay Kit generates a large signal, thus researchers are able to generate results that offer enhanced sensitivity, quicker time to results, and greater signal to noise, even at the highest throughput rates and plate densities," notes Duncan McBranch, Ph.D. Co-founder and President at QTL Biosystems.
"Researchers will soon be able to harness this technology to screen for multiple drug targets and compound libraries," stated David Whitten, Ph.D. Co-founder and CTO at QTL Biosystems.
Fluorescence-based assays are among the most important screening techniques used in pharmaceutical drug discovery. A technique commonly used is FRET (fluorescence resonance energy transfer). FRET reactions typically couple a single fluorophore with a single quencher molecule.
In contrast, QTL LIGHTSPEED ("QTL" stands for "quencher-tether-ligand") couples a quencher molecule with a fluorescent polymer chain. Each quencher alters fluorescence of several hundred fluorophores thus leading to enhanced sensitivities. QTL's technology offers a significant performance advantage enabling greater sensitivity, specificity, shorter time to results, and material cost savings.
