HTRF ® Product Catalog April 2018 5 th edition
Over the years, the HTRF product portfolio has become the broadest no-wash assay platform available for biochemical and cell-based assessment of intracellular and secreted proteins and metabolites. And its expansion continues to match the main therapeutic and research trends, thanks to our interaction and collaborations with scientists worldwide!
So in a nutshell, what are the new assays you’ll find in this year’s edition? Not surprisingly, NASH, oncology and immuno-oncology remain at the forefront of drug research trends, and have rightly earned our particular attention:
• For NASH, EIF2a and FoxO1 now enrich our portfolio of phospho- and total-protein assays. Hyaluronic acid, a-SMA and Procollagen-III-peptide come as unique supplements for this paramount therapeutic indication.
• Our investigations into oncology and immuno-oncology topics have been converted into a range of checkpoint inhibitor biochemical kits, but also into new Granzyme B, Perforin, phospho- and total NDRG1 assays, among others.
Fresh out of the lab is Cisbio’s new a-Tubulin assay, a housekeeping protein assay optimized for total compatibility with our phospho-protein assays.
What else is new? Lots of new content online, expert guides, tips and application notes, entertaining (and educational) videos, and other wide-ranging scientific material that can ease your research efforts.
And if this is the first time you have this catalog in hand, and you are still unfamiliar with- or scared of using - HTRF assays, we have designed a brand new web environment that will walk you through the first steps of no-wash assay implementation. Don’t miss the trip!
Speed up your research projects!

Cell-based Tag-lite® assays
Tag-lite is a cell-based, no-wash alternative to traditional radioisotope assays for studying GPCR-ligand interaction.
The receptor of interest is expressed as a SNAP-tag® fusion protein, which is labeled in situ with an HTRF® donor fluorophore, while the ligand is conjugated with the HTRF® acceptor fluorophore.
Tag-lite offers you:
• Saturability and high affinity determines Kd values
• Reversibility and specificity correlates Ki with radioactive data
• Functionality second messenger accumulation is unaffected by SNAP-tag®
• A DIY process to label your own receptor

Enzymatic assays
Substrates and regulatory proteins
The substrates are designed to monitor protease cleavage of peptidic substrates. A typical format uses a substrate that is biotinylated on one end and directly labeled with Europium cryptate on the other. The detection step is made in presence of SA-XL665. The enzymatic activity is inversely proportional to the intensity of the FRET signal. For enzymes with high Km constants, the addition of unlabeled substrate may be required to run the enzymatic reaction efficiently.
Similarly, Eu-cryptate ubiquitin can be used as a conjugated protein to study the different enzymatic steps of the protein ubiquitination cascade: activation (E1), conjugation (E2), and ligation (E3). The ubiquitin donor conjugate is most commonly used with biotinylated or tagged target proteins which can then be detected by SA-XL665 or anti-tag acceptor conjugates.

HTRF® technology combines standard FRET with time-resolved measurement of fluorescence
FRET (Fluorescence Resonance Energy Transfer) is based on the transfer of energy between two fluorophores, a donor and an acceptor, when in close proximity.
When two entities come close enough to each other, excitation of the donor by an energy source (e.g. a flash lamp or a laser) triggers an energy transfer towards the acceptor, which in turn emits specific fluorescence at a given wavelength.
The detection of specific fluorescence at the acceptor’s maximum emission wavelength (i.e. 665 nm, shown in red) is a sign that FRET has occurred, due to the proximity of the two interacting partners.
Time-resolved measurement of fluorescence eliminates short-lived background fluorescence from sample components.
The HTRF® donors have a long fluorescence life. The energy pulse from the excitation source (flash lamp, laser) is then immediately followed by a time delay, allowing interfering short-lived fluorescence (compounds, proteins, medium, etc.) to decay.
Because of these spectral properties, a donor-acceptor complex can be detected without the need for physical separation from the unbound partners. Fully homogeneous, HTRF® does not require separation steps such as centrifuging, washing, filtration, or magnetic partitioning.
HTRF® fluorescent partners
The HTRF® energy donor consists of a rare earth complex in which the lanthanide ion is tightly embedded in a macro cycle. The unique HTRF® cryptate structure produces stable emissions under a wide range of chemical conditions. These properties enhance the assay window, overall sensitivity, and technology robustness.
HTRF® uses various fluorophores, donors, and acceptors to form several TR-FRET pairs with the required FRET properties.
Two HTRF® donor fluorophores: Two HTRF® acceptor fluorophores:
• Europium cryptate (Eu3+cryptate) • XL665
• Lumi4®-Terbium cryptate (Tb3+cryptate)
• d2

Incomparable miniaturization capabilities
Fluorescence intensity is concentration-dependent rather than quantity-dependent, unlike radioactivity and luminescence.
Proportional reagent volume downsizing offers a straightforward way to miniaturize HTRF® assays to high density formats such as 384 low-volume or 1,536-well plates.
Ratiometric measurement is critical for eliminating compound interference
HTRF® emissions are measured at two wavelengths, and the ratio of the fluorescence of the acceptor over that of the donor is calculated.
Emissions at 620 nm (donor fluorescence) are used as an internal reference, while emissions at 665 nm (acceptor fluorescence) are used as an indicator of the biological reaction being assessed. A filter effect may occur because of differences in medium additives and/or compound concentrations, which leads to a decrease in the excitation energy delivered. The fluorescence ratio compensates for this phenomenon because both acceptor and donor emissions are affected in the same manner.
