HTS Assay Kits
ADP detection with HTRF® quality.The HTRF® Transcreener™ ADP assay is a homogeneous non-radioactive assay which measures the generation of ADP. This universal solution can be used to assess kinase and ATPase activity for High Throughput Screening and profiling applications. Enzyme-free detection allows for a low false positive rate. ADP is directly detected by a monoclonal antibody labeled with Eu3+ cryptate and correlates tig…
In 2008 Gentronix launches a new S9 protocol to extend the application of the GreenScreen HC assay to include the detection of genotoxic metabolites. Many pharmaceuticals only present a genotoxicity hazard after metabolism and such chemicals are called pro-mutagens or pro-genotoxins. Generally, although not exclusively, the liver is considered responsible for the “metabolic activation” (MA) of promutagens. However, none of t…
Cisbio's cAMP HiRange kit is designed to address either the use of cell-based and cellular membranes-assays in GPCR activation and Adenylate Cyclase activity screening. The cAMP HiRange assay is highly robust and produces quality results while eliminating the need for a continuous supply of living cells.
IP1, a downstream metabolite of IP3, accumulates in cells following Gq recepetor activation and is stable in the presence of LiCl making it an ideal GPCR (Gq) functional assay. Cisbio developed and patented a highly accurate HTRF assay for measuring IP1 in 96-, 384- and 1536-well formats providing for a HTS compatible assay.
Cyclic GMP (Guanosine 3',5'-cyclic monophosphate) is a major second messenger that mediates cell activities by activating protein effectors such as protein kinase G (PKG), cGMP-regulated phosphodiesterases (PDEs), and cGMP-gated channels. Cellular cGMP is synthesized by soluble Guanylyl Cyclases and particulate Guanylyl cyclase, triggered by nitric oxide and atrial natriuretic peptide (ANP) binding respectively. Key processes…
An acetyl-biotinylated substrate recognized by a Eu3+ anti-acetyl MAb and SA-XL665, which is used in activator screening or to test an High Throughput SIRT1 inhibitor. The level of enzymatic activity is inversely proportional to the amount of signal produced in the system. For more information please visit Cisbio Bioassays website.
In order to provide you with the most advanced tools for GPCR cell-based assays HTRF Technology now incorporates Lumi4®-Tb chemistry. Lumi4®-Tb is the first and only TR-FRET terbium cryptate, and is fully compatible with all existing HTRF readers. Therefore IP-One Tb offers new levels of sensitivity and performance in cell-based assays.

BlueScreen HC is based on the fast, accurate GreenScreen HC genotoxicity assay from Gentronix Ltd. BlueScreen HC uses the same human-derived, p53-competent TK6 cells to host a patented reporter system that exploits the proper regulation of the GADD45a gene. However, in place of GFP, BlueScreen HC utilizes a luciferase from the marine copepod Gaussia princeps to generate a luminescent output. The BlueScreen luminescent assa…
Cisbio Bioassays has developed Cellul'erk, a highly accurate HTRF assay for measuring phosphorylated ERK1/2 in 96-, 384- and 1536-well formats providing for an HTS compatible assay.

G-Protein Coupled Receptors (GPCRs) are common drug targets. Previously, most studies were based on the monomeric model, but this perception of GPCRs is now evolving towards homodimeric , heterodimeric and oligomeric models. To facilitate research into GPCR dimers, CisBio Bioassays has applied the Tag-lite® technology to GPCR interaction assays. Based on HTRF® technology, plasmids have been designed to express either the SNA…
