NHRscan - Nuclear Hormone Receptor Panel

LeadHunter® Discovery Services, offers a large menu of cell-based nuclear hormone receptor (NHR) assays to examine the effects of chemicals, drugs and nutrients on nuclear receptor activity. We offer over 26 different cellular assays that monitor receptor activation by either nuclear translocation or NHR co-activator interaction - but without the lengthy compound incubation times inherent with traditional reporter gene assays. Screen compounds against our complete panel of assays or select your own customized group of receptors based on therapeutic relevance (Toxicology, Metabolic Diseases, Endocrinology). Our experienced and highly-qualified service team will provide you the data you need, quickly and without using your own internal resources to allow you to meet your project needs.

Comprehensive Menu

Powered by the PathHunter® technology, our NHR assays are whole cell, functional assays that measure NHR translocation and NHR-coactivator interaction. Unlike standard reporter gene assays, these assays are chemiluminescent and do not require lengthy 16-24 hour compound incubations making them ideal assays for screening and profiling.

Panel Highlights and Benefit

  • Functionally validated cell lines – high quality results every time
  • High quality, functional data - Accurate, precise and reproducible
  • Flexible options – either pre-defined panels of personalized assay selection
  • Agonist and antagonist modes available
  • Broad applications – specificity and compound toxicity/liability
  • Rapid data turnaround time

Choose from the following:

Co-Activator Interaction (NHRPRO)

Measure interactions between the NHR and Steroid Receptor Co-activator Peptides (SRCP).
    

Nuclear Translocation (NHRTRANS)

Measure receptor activity based on translocation of the NHR following ligand stimulation.

Ideal for Screening and Profiling

The simplicity and versatility of the PathHunter® NHRTRANS and NHRPRO assays make these assays ideal for screening and profiling to look for agonists, antagonists, inverse agonists.NHR_PathHunterScreenProfile.png

Determine Mechanism of Action

LeadHunter Discovery Services can provide you complete characterization of your lead compounds by offering multiple readouts for the same nuclear receptor. Using a combination of translocation and protein-protein  interaction assays for the same NHR target, the LeadHunter team will help you study the mechanism of action of your lead compound in order to better predict compound activity in vivo.

The PathHunter GR Nuclear translocation assay shows no inhibition after addition of Mifepristone (B) while the NHRPRO GR assay shows almost complete inhibition of the Dexamethasone response, indicating that Mifepristone acts on the target of interest by blocking co-activator recruitment.

Flexible Screening & Profiling Options

LeadHunter Discovery Services reduces the time and costs associated with drug discovery. Whether you are interested in full panel screening and profiling, or selecting a subset of assays, we offer the selection and flexibility to support your drug discovery needs.
