Degradation Compound Profiling Services
Endpoint Degradation Profiling
Ideal for screening large compound libraries
- Single concentration or dose response to determine DC50
- Multiple time points to assess fast (5–6 hours) and sustained (18–24 hours) degradation
- Cell viability multiplex
Kinetic Degradation Profiling
Ideal for ranking kinetic parameters of hit degraders
- Single concentration or dose response monitored for 24 hours
- Analysis of degradation rate, Dmax and Dmax50 against concentration to evaluate kinetic potency
- Endpoint cell viability multiplex
Endogenously Tagged HiBiT Neosubstrate Panel to Enable Molecular Glue Discovery
Six neosubstrate targets for IMiD molecular glues were established as HiBiT CRISPR knock-in cell lines across different cell types: IKZF1 and IKZF2 (Jurkat), IKZF3 (MM.1S), SALL 4 (SK-N-DZ), CK1α and GSPT1 (HEK293). This neosubstrate panel enables screening for molecular glue library degradation selectivity and off-target effects with CRBN-recruiting PROTACs. Recommended endpoints for screening include 6 and 24 hours, with concurrent cell viability counter-screen. RLU values were normalized to CellTiter-Glo® Luminescent Cell Viability Assay.
Permeability and Affinity Services
NanoBRET® Target Engagement and Cellular Permeability
- De novo assay and tracer development
- Assessment of degrader binding affinity to target and E3
- Assessment of degrader permeability in live vs permeabilized cells
Degrader Results with Automated VHL TE Assay
Panel A. Compound concentration-response curves from NanoBRET® TE VHL assays in live-cell or permeabilized-cell modes, respectively. VH298 was used as a permeable control compound. Panel B. Lower and upper asymptote, IC50, and Hill slope parameters calculated from non-linear regression curves.
VHL TE Assay Permeability Parameters
Calculated relative binding affinity (RBA) and availability index (AI) values for each compound. An RBA value of approximately 1 indicates similar free concentrations inside and outside of the cell. AI > 1 suggests reduced availability inside the cell compared to VH298 control. AI < 1 could indicate compound accumulates in cells at higher relative concentrations compared to VH298 control.
Ternary Complex Formation Services
NanoBRET® Ternary Complex Formation
- De novo assay development and testing
- Degrader profiling in endpoint or kinetic format
- Single concentration or dose response
Screening for Neosubstrate Ternary Complex Formation with Transient NanoBRET® Assay
NanoBRET® Ternary Complex Assay optimization for common neosubstrates and CRBN. NanoLuc® neosubstrate and HaloTag® CRBN fusions were expressed in HEK293 cells with or without protease inhibitor MG132. All N- and C- orientations were tested at 1:10 and 1:100 ratios. Results show a significant increase in BRET upon addition of molecular glue due to formation of ternary complex.
