背景介绍 Caspase-7 is a member of the caspase (cysteine aspartate protease) family of proteins, and has been shown to be an executioner protein of apoptosis. 产品介绍 The Homogeneous Caspase-7 Assay Kit is a complete assay system designed to measure Caspase-7 activity for screening and profiling applications. It comes in a convenient 96-well format, with all the reagents necessary for 100 fluorescent Caspase-7 activity measurements. In addition, the kit includes purified Caspase-7 enzyme and a potent Caspase-3/7 inhibitor, Ac-DNLD-CHO, for use as a positive and negative control. Using this kit, only one simple step on a microtiter plate is needed to analyze the Caspase-7 activity level. The fluorogenic substrate, Ac-DEVD-AFC, is incubated with purified Caspase-7 and the enzymatic activity releases AFC fluorophore that can then be measured using a fluorescence reader.

询价产品介绍 Streptavidin-HRP is useful in select BPS Bioscience assay kits.
询价背景介绍 Activated PARP cleaves NAD+ to nicotinamide and ADP-ribose and polymerizes the ADP-ribose on nuclear acceptor proteins such as histones, transcription factors, and PARP itself. Biotinylated NAD+ (6-Biotin-17-NAD+) provides a non-isotopic alternative to radiolabeled NAD+ for assays requiring this substrate. Biotinylated NAD+ can be used as an indirect measure of PARP activity when biotin incorporation is detected using a streptavidin detection system. Biotinylated NAD+ is also useful for labeling or purifying proteins via poly (ADP)ribosylation. 产品介绍 NAD+ covalently labeled with biotin (6-biotin-17-nicotinamide-adenine-dinucleotide). Can be used as a substrate by poly(ADP-ribosyl) polymerase (PARP) enzymes for generating biotin-labeled ADP-ribose monomers in PARylation reactions.
询价背景介绍 PARP is found in the cell's nucleus. The main role is to detect and signal single-strand DNA breaks (SSB) to the enzymatic machinery involved in the SSB repair. PARP activation is an immediate cellular response to metabolic, chemical, or radiation-induced DNA SSB damage. Once PARP detects a SSB, it binds to the DNA, and, after a structural change, begins the synthesis of a poly (ADP-ribose) chain (PAR) as a signal for the other DNA-repairing enzymes such as DNA ligase III (LigIII), DNA polymerase beta (pol?), and scaffolding proteins such as X-ray cross-complementing gene 1 (XRCC1). After repairing, the PAR chains are degraded via Poly(ADP-ribose) glycohydrolase (PARG). Both PARP-1 and PARP-2 are activated by DNA single-strand breaks. 产品介绍 Activated DNA for PARP assay, for use with BPS's assay kits for PARPs 1, 2, 3, and 6. PARP1 Chemiluminescent Assay Kit, #80551 ; PARP2 Chemiluminescent Assay Kit, #80552; PARP3 Chemiluminescent Assay Kit, #80553; PARP6 Chemiluminescent Assay Kit, #80556; PARP2 Homogeneous Assay Kit, #80702
询价产品介绍 The 10x PARP Assay Buffer is optimized for use with BPS Bioscience's poly(ADP) ribose polymerase (PARP) assay kits.
询价产品介绍 Contains biotinylated substrate
询价产品介绍 The TNKS2 Histone Ribosylation Colorimetric Assay Kit is designed to measure Tankyrase 2 (TNKS2) activity for screening and profiling applications. TNKS2 catalyzes the NAD-dependent addition of poly(ADP-ribose) to the substrate proteins. The key to the TNKS2 Histone Ribosylation Assay is the biotinylated NAD+ substrate. With this kit, only three simple steps are required for TNKS2 reactions. First, histone proteins are coated on a 96-well plate. Next, the biotinylated NAD+ substrate is incubated with an assay buffer that contains the TNKS2 enzyme. Finally, the plate is treated with streptavidin-HRP followed by addition of the colorimetric HRP substrate to produce color that can then be measured using a UV/Vis spectrophotometer microplate reader.
