The assay involves two monoclonal antibodies, one labeled with Cryptate and the other with XL665, that recognize distinct determinants. The assay is performed in a single step and requires only a short incubation period. Detection limit of the assay is 0.20 ng/mL and the linear range covers 0.3 to 10 ng/mL. The assay has been validated on various biological material including isolated perfused pancreas, plasma, and pancreatic…
Universal Assay for Serine/Threonine KinasesCisbio's line of HTRF® KinEASE™ STK kits are based on our patented HTRF® technology and can be used as a universal tool for assessing Serine/Threonine kinase activity. These assays use a proprietary antibody and a choice of three biotinylated substrates developed by Upstate to rapidly produce high quality kinase results. Our HTRF KinEASE™ STK kits have been validated on more than 107…
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.
Three kits to cover a wide range of cAMP concentrations.After the introduction of IP-One, the first HTS immunoassay that can easily detect inositol(1)phosphate (IP1), a stable second messenger which tightly correlates with Gq-coupled receptor activity, the optimization of cAMP assays with the new HTRF® acceptor d2 offers a complete GPCR platform.The upgraded cAMP dynamic 2 and cAMP femto 2 assays, along with the new cAMP HiRa…
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 rapid and sensitive homogeneous assay for cortisol assessmentThe HTRF® cortisol assay can be used for the quantification of cortisol in rodent serum, or directly on cells. This assay has also been validated for 11-beta HSD1 screening on whole cells or microsomes.The assay requires only 2 reagent additions, followed by an incubation period of 2 hours at room temperature. It has a detection limit of 70 pg/mL (e.g. 2 fmol/well…
A straightforward tool for biomolecular labeling with Europium cryptateThe Cryptate labeling kit includes all the necessary materials to allow rapid Cryptate labeling of various biomolecules and purification. The labeling reagent Eu3+-TBP-NHS Cryptate is suitable for labeling peptides, proteins, and oligonucleotides, as well as small molecules containing amino groups (N-terminus or lysine residues). The labeling procedure requ…
A range of HTRF® conjugates for assay developmentHTRF® toolbox assembles a panel of detecting reagents such as Streptavidin-XLlent!, anti-tag antibodies like Eu-Cryptate anti-GST, 6HIS, DNP and anti species conjugated antibodies offering many possibilities for the study of molecular mechanisms. All reagents are available as Cryptate-Europium or XL665 (the two HTRF tracers) conjugates, to allow easy assay development. These re…
Streamlined single plate protocols including all stimulation and cytokine quantification.The HTRFâ cytokine kit line includes TNFa, IFNg, IL1b, IL6 and IL8 assays. These assays feature no separation steps, a high sensitivity and dynamics, and no use of isotopes. Procedures are performed on a single plate with simultaneous cell stimulation and cytokine detection. They can all be run under a similar experimental procedure stream…
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…
