背景介绍 The pandemic coronavirus disease 2019 (COVID-19) is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). As a first step of the viral replication strategy, the virus attaches to the host cell surface before entering the cell. The Spike protein recognizes and attaches to the Angiotensin-Converting Enzyme 2 (ACE2) receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. Drugs targeting the interaction between the Spike protein of SARS-CoV-2 and human ACE2 may offer some protection against the viral infection. 产品介绍 The Spike S1-Biotin (16-685) (SARS-CoV-2): ACE2 TR-FRET Assay is designed to measure the inhibition of the binding between SARS-CoV-2 Spike S1 and human ACE2 in a homogeneous 384 reaction format. This TR-FRET-based assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple; the test inhibitor compound is incubated with biotinylated Spike S1, Eu-labeled ACE2, and the dye-labeled acceptor for one hour. Then the TR-FRET signal is measured using a fluorescence reader capable of measuring Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET).
询价背景介绍 Middle East Respiratory Syndrome coronavirus (MERS-CoV) poses a significant threat to public health worldwide due to its ability to cause serious human disease with high mortality rates. MERS-CoV has become a global threat due to continuous outbreaks in countries on the Arabian Peninsula and the potential for spread to other countries. MERS-CoV 3CL protease is essential for viral replication; consequently, it is an attractive target for small molecule therapeutics. 产品介绍 The 3CL Protease (MERS-CoV) Inhibitor Screening Assay Kit is designed to measure 3CL Protease activity for screening and profiling applications, in a homogeneous assay with no time-consuming washing steps. A protease inhibitor cocktail is included as a positive control. Assay Principle: 3CL Protease (MERS-CoV) Assay Kit uses a custom-synthesized peptide which has a fluorescence group quenched by a specific quencher. This peptide works as a substrate for 3CL Protease (MERS-CoV). After proteolytic cleavage, fluorescence product is formed and detected at λexcitation=485 nm and λemission=528 nm.
询价背景介绍 The COVID-19 pandemic is caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The Spike glycoprotein is expressed on the surface of the virus as a trimer. Each Spike protein consists of two subunits, S1 and S2, and the S1 subunit contains the receptor binding domain (RBD) which recognizes and attaches to the ACE2 receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. SARS-CoV-2 Variant B.1.617.2, also known as Delta variant, was originally discovered in India and contains mutations L452R and T478K.

The Spike S1 RBD (B.1.617.2; Delta Variant) (SARS-CoV-2) protein (BPS Bioscience #101153) in this kit consists of the RBD region (amino acids 319-541 with mutations L452R and T478K), which includes the ACE2 binding site. 产品介绍 The Spike S1 RBD (B.1.617.2; Delta Variant) (SARS-CoV-2): ACE2 Inhibitor Screening Colorimetric Assay Kit is designed for screening and profiling inhibitors or neutralizing antibodies of the interaction between SARS-CoV-2 Spike and human ACE2. The assay requires only a few steps. First, Spike S1 RBD (B.1.617.2; Delta Variant) (SARS-CoV-2) is coated on a 96-well plate overnight. After blocking, the protein is pre-incubated with the inhibitor or neutralizing antibody. Upon subsequent incubation with Biotin-ACE2, the plate is treated with Streptavidin-HRP followed by addition of a colorimetric HRP substrate to produce color, which can be quenched and measured using a UV/Vis microplate reader.

询价背景介绍 SARM1 is the executioner of the axonal degeneration pathway that promotes depletion of axonal NAD+. SARM1 functions as an ADP-ribosyl cyclase and nicotinamide adenine dinucleotide (NAD) glycohydrolase. Dimerization of SARM1-TIR domains in neurons induces axonal degeneration since SARM1-TIR domains have intrinsic NADase activity which cleave NAD+ into ADP Ribose (ADPR), cyclic ADPR, and Nicotinamide. Depletion of axonal NAD+ triggers pathological axon loss. Therefore, inhibition of SARM1 NAD+ cleavage activity may potentially reduce axonal degeneration. 产品介绍 The SARM1 Fluorogenic Assay Kit (Hydrolase Activity) is designed to measure NAD+ cleavage activity for screening and profiling applications.
询价背景介绍 Janus kinases (JAKs) are a family of intracellular nonreceptor tyrosine kinases including JAK1, JAK2, JAK3 and Tyk2, that has been recognized as an important modulator in inflammatory processes. JAKs contain a catalytically inactive pseudokinase regulatory domain (JH2) as well as an active kinase domain (JH1). Selective inhibition of one specific JAK is a challenging task since the enzymes share high homology in the active site of JH1. Recent reports demonstrate that the pseudokinase domain (JH2) could provide an ideal allosteric site for selective inhibitors. 产品介绍 The JAK2 JH2 Pseudokinase Domain Inhibitor Screening Assay Kit is designed for screening and profiling small molecules that displace the fluorescently labeled probe (JH2 probe 1) from the JH2 domain of JAK2. The assay is a fluorescence polarization (FP) assay based on the competition of the test compound with the JH2 probe for binding to purified JAK2 JH2. JH2 probe 1 is a small molecule probe that binds to the ATP-binding site of JAK2 pseudokinase domain JH2. The probe has been labeled with a fluorescent tracer, so that binding of the probe to much larger JH2 results in noticeable increases in fluorescence polarization compared to the unbound fluorescent probe (depolarized). Competition between a test drug and the probe results in changes in polarization. Using this kit, only one simple step on a microplate is required for screening. The JH2 probe 1 is incubated with a sample containing JAK2 JH2 to produce a change in fluorescent polarization that can then be measured using a fluorescence microplate reader capable of measuring fluorescence polarization.
