The DPPIV-Glo™ Protease Assay is a homogeneous, luminescent assay that measures dipeptidyl peptidase IV (DPPIV) activity. DPPIV is a serine protease that cleaves N-terminal dipeptides from polypeptides with L-proline or L-alanine at the penultimate position. The DPPIV-Glo™ Assay provides a proluminescent DPPIV substrate, Gly-Pro-aminoluciferin, in a buffer system optimized for DPPIV and luciferase activities. The addition of a…

The ONE-Glo™ Luciferase Assay System provides a highly sensitive, robust, homogeneous assay for detection of firefly luciferase reporter gene expression in mammalian cells. Ideally suited for high- and ultrahigh-throughput applications, the ONE-Glo™ Assay contains a new luciferase substrate, resulting in a reagent that is more stable, more tolerant to sample components, and has less odor than standard luciferase assay reagents…

The ApoTox-Glo™ Triplex Assay combines three assay chemistries to easily assess viability, cytotoxicity and apoptosis events in the same cell-based assay well. First, viability and cytotoxicity are determined by measuring two differential protease biomarkers simultaneously with the addition of a single nonlytic reagent containing two peptide substrates. The live-cell protease activity is restricted to intact viable cells and i…

The Griess Reagent System measures nitrite (NO2–), which is one of two primary stable and nonvolatile breakdown products of nitric oxide (NO). Nitric oxide is an important physiological messenger and effector molecule in many biological systems, including immunological, neuronal and cardiovascular tissues. This assay relies on a diazotization reaction that was originally described by Griess in 1879. Through the years, many mod…

The QuantiFluor™ RNA System contains a fluorescent RNA-binding dye that enables sensitive quantitation of small amounts of RNA in solution. Detecting and quantitating small amounts of RNA is a very important step used in many biological applications, particularly in molecular biology techniques. These include measuring yields of in vitro transcribed RNA and measuring RNA concentrations before performing Northern blot anal…

The ROS-Glo™ H2O2 Assay is a homogeneous, fast and sensitive bioluminescent assay that measures the level of hydrogen peroxide (H2O2), a reactive oxygen species (ROS), directly in cell culture or in defined enzyme reactions.   This assay allows identification of conditions or test compounds, such as small molecule inhibitors or inducers, that alter ROS levels. The scalable multiwell format couples a stable luminescent si…

Trypsin/Lys-C Mix, Mass Spec Grade, is a mixture of Trypsin Gold, Mass Spectrometry Grade, and rLys-C, Mass Spec Grade. The Trypsin/Lys-C Mix is designed to improve digestion of proteins or protein mixtures in solution.   Using the conventional trypsin digestion protocol (i.e., overnight incubation at nondenaturing conditions), Trypsin/Lys-C Mix improves protein digestion by eliminating the majority of missed cleavages,…

Polyclonal secondary antibodies raised in goat, rabbit or donkey, immunoaffinity-purified using corresponding immobilized antigens and conjugated to horseradish peroxidase (HRP) enzyme.   The Anti-Human IgG (H+L), HRP Conjugate, Anti-Mouse IgG (H+L), HRP Conjugate and Anti-Rabbit IgG (H+L), HRP Conjugate antibodies bind to both heavy and light chains for all IgG subclasses. As with all antibodies, in certain applications…

Trypsin is a serine protease that specifically cleaves at the carboxylic side of lysine and arginine residues.   The stringent specificity of trypsin is essential for protein identification. Native trypsin is subject to autolysis, generating pseudotrypsin, which exhibits a broadened specificity including a chymotrypsin-like activity. Such autolysis products, present in a trypsin preparation, would result in addition…

The LigaFast™ Rapid DNA Ligation System is designed for the efficient ligation of sticky-ended DNA inserts into plasmid vectors in just 5 minutes (blunt-ended inserts in as little as 15 minutes).   Rapid ligation is based on the combination of T4 DNA Ligase with a unique 2X Rapid Ligation Buffer to speed up and streamline your cloning experiments. The LigaFast™ System is designed to eliminate any further purification pri…
