This HTRF kit detects changes of cAMP accumulation in response to Gs coupled GPCR activation or inhibition.

Cisbio offers a line of three ready-to-use assays for measuring cAMP using HTRF® technology. Each kit is optimized for detecting a specific range of cAMP concentrations to allow fine tuning of assay sensitivity. These kits enable high quality, cell-based assay screening in 96-, 384- or 1536-well formats.

The Human IgG kit is designed for the fast quantification of human IgG.  

An easy way to assess tag accessibilityThe production of fusion proteins often raises the issues not only of their structural integrity after isolation, but also of the accessibility of the associated tag. In the case of GST or 6HIS tagged proteins, this verification can be achieved with HTRF® GST and 6HIS check kits. These two assays are competitive immunoassays in which the anti-GST or anti-6HIS Cryptate conjugates bind dire…

A new secondary messenger for Gq coupled receptor investigation.Cisbio’s IP-One assay, based on its proprietary HTRF® technology, is the first HTS immunoassay that can easily detect inositol(1)phosphate (IP1), a stable second messenger which tightly correlates with Gq-coupled receptor activity. This assay displays all the characteristic advantages of an HTRF® system: totally homogeneous, detection via fluorescence, signal stab…

IP-One ELISA assay kit from Cisbio Bioassays - Simple and highly accurate measurement of IP1 IP1, a downstream metabolite of IP3, accumulates in cells following activation of Phospholipase C (PLC) coupled receptors. Among them, the Gq coupled GPCRs represent the most important family of receptors which can activate the β subtype of the PLC family. Other receptor types, like protein tyrosine kinase receptors, antigen or immuno…

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.

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. Features: • Simple assay protocols designed for research studies (96-well plates) for HTS (384-small vol. plates) • Cell-based functional assay • Antibody-based detection • Direct detection Applications: • Gi, Gs, or Gq coupled receptor activatio…

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…

Tag-lite® cell-lines and reagents, a multimodal environment streamlined for GPCR studies. Cellular trans-membrane receptors are high potential therapeutic targets in pharmacological research, among them G-Protein Coupled Receptors (GPCRs). To reach a better physiological understanding, their study is deepening and is now focusing on structural assessments (ligand binding, dimerisation) and also on multiple signal pathway assa…
