The basis for quality and reproducibility of the analysis

The key to reproducible results by development under standardized conditions

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…

A simple and straightfor­ward procedure for measuring functional kinase activity.The Eu(K) labeled antibody and XL665 conjugate are added simul­taneously after the enzymatic step. Results are available after a 2-hour incubation at room temperature. The two reagents are stable in solution, even in an excess of EDTA (0.5M), while the assay remains stable for >24 hours. An extended list of Eu3+-Cryptate labeled phos­pho-specific…

An homogeneous fluorescence assay for PGE2Prostaglandin E2 (PGE2) is a primary product of arachidonic metabolism in many cells. Under inflammatory stimuli, PGE2 is de novo synthesized by three enzymatic steps via the cyclooxygenase (COX) pathways. PGE2 production is commonly used in the detection of COX-1 and COX-2 activity. In the PGE2 HTRF® assay, free PGE2 from the sample competes with XL665 labeled PGE2 for binding to a Cr…

The assay involves two monoclonal antibodies, one labeled with Cryptate and the other with XL665, that recognize distinct determinants.
