Our potent CELT-150 VHL E3 ligase fluorescent ligand is a tracer for VHL E3 ligases binding assays, designed to perform affinity binding curves to VHL protein using TR-FRET homogenous technology. Von Hippel–Lindau protein (VHL) is the substrate recognition subunit of an E3 ligase recruited by bifunctional Proteolysis-targeting chimeras (PROTACs) to induce ubiquitination and subsequent proteasomal degradation of a targeted protein.

Our hA3 Adenosine receptor fluorescent antagonist shows a high affinity and selectivity for A3 receptor over the other receptor subtypes (Ki =6.13 nM for A3 receptor in radioligand binding assay). It allows to perform cell visualization in fluorescence microscopy, confocal microscopy and high content system experiments. It is potentially suitable for other fluorescence-based assays.

Our hD2 Dopamine receptor fluorescent antagonist shows high affinity for hD2 receptor and selectivity over the other receptor subtypes (Ki =1.06 nM for hD2 receptor in radioligand binding assay). It allows to perform cell visualization in fluorescence microscopy, confocal microscopy and high content system experiments. It is potentially suitable for other fluorescence-based assays.

Our h5HT2B Serotonin receptor fluorescent ligand shows a high affinity for 5HT2B serotonin receptor and high selectivity over the other receptor subtypes (Ki =56.32 nM for 5HT2B receptor in radioligand binding assay).It allows to perform cell visualization in fluorescence microscopy, confocal microscopy and high content system experiments. It is potentially suitable for other fluorescence-based assays.

Our CELT-252 ligand is a highly potent fluorescent antagonist developed for hA1R testing with a Ki of 39 nM in radioligand binding assay. The product comes in a 10ug vial that enables the preparation of 69ml of 100nM working solution to test AT1R. Our fluorescent antagonist is ideal for visualization in confocal microscopy and high-content system experiments. Our CELT-252 ligand is potentially suitable for other fluorescence-based assays such as Fluorescence Polarization.

Our h5HT2A/5HT2C Serotonin receptor fluorescent antagonist shows a high affinity for h5HT2A/h5HT2C serotonin receptors (Ki =29.7 nM and 14.6 nM respectively in radioligand binding assay).It allows to perform cell visualization in fluorescence microscopy, confocal microscopy and high content system experiments. It is potentially suitable for other fluorescence-based assays.

Our hD2 Dopamine receptor fluorescent antagonist shows high affinity for hD2 receptor and partial selectivity over the other receptor subtypes (Ki =89.3 nM for hD2 receptor in radioligand binding assay). It has been validated in Fluorescence Polarization binding assays as a valid alternative to radioligand binding assays.It allows to perform cell visualization in fluorescence microscopy, confocal microscopy and high content system experiments. It is potentially suitable for other fluorescence-based assays.

Our potent Sigma h σ1/σ2 receptor fluorescent ligand is available in a 10ug vial, allowing you to prepare 103 ml of 100nM working solution to test σ1/σ2 receptors. Our CELT-483 product has been specifically designed to meet the needs of researchers in a variety of fields, enabling the study of σ1 and σ2 receptors with accuracy and precision. It has been validated in flow cytometry (Kd=13,59 nM for σ2) and confocal microcopy in MCF7 cell lines (see publication for more details) to study both σ1 and σ2 receptors, using the appropriate masking agent.

Our potent C5a receptor fluorescent antagonist shows high affinity for the C5aR (EC50 = 24.89 nM by saturation binding in Chem1 transfected cells), good potency (KB= 5.8 μM by calcium flux assay) and good competition with the endogenous ligand C5a. It has been validated in flow cytometry competition binding assays using Chem1 transfected cells. It is potentially suitable for other fluorescence-based assays.
