San Jose, CA – March 12, 2009
AnaSpec, known for developing sensitive, long wavelength assays, is pleased to announce the release of another long wavelength protease assay – the SensoLyte® Rh110 Plasmin Activity Assay Kit (Ex/Em=496 nm/520 nm).
Plasmin is a serine protease derived from the conversion of plasminogen in blood plasma by plasminogen activators.1 Its primary function is to degrade fibrin in blood clots.1 Plasmin activators and inhibitors are thought to be the key participants in the balance between proteolytic and antiproteolytic activities that regulate extracellular matrix degradation.2 In addition to its established role in fibrinolysis, plasmin is also involved in several pathological and physiological processes such as embryogenesis, ovulation, inflammation, wound healing, angiogenesis, neoplasia, and metastasis.2
The SensoLyte® Rh110 Plasmin Assay Kit provides a convenient assay for screening of enzyme inhibitors and activators or for continuous assay of enzyme activity using a fluorogenic substrate. Upon plasmin protease cleavage, this substrate generates the Rh110 (rhodamine 110) fluorophore which has a bright green fluorescence and can be detected at Ex/Em=496 nm/520 nm. The longer-wavelength spectra and higher extinction coefficient of the Rh110 provide greater sensitivity and less interference from other reaction components.
AnaSpec is a leading provider of integrated proteomics solutions to the world’s largest biotech, pharmaceutical, and academic research institutions. With a vision for innovation through synergy, AnaSpec focuses on three core technologies: peptides, detection reagents, and combinatorial chemistry.
