2bind Services – Fragment-based Drug Discovery Services

Fragment-based Drug Discovery: Use 2bind’s Biophysics Services for competitive timelines and throughput to promote your therapeutic program

Fragment-based Drug Discovery Services

In fragment-based drug discovery, the precision of biophysical tools becomes paramount to deal with extremely small chemical entities. Regardless of your position in the discovery journey, 2bind’s specialized services ensure the delivery of essential insights for informed decision-making. From navigating molecules with weak affinities to handling rapid kinetics, our expertise empowers you to make the right choices at every step.

Screen for binding with TRIC (MST), Spectral Shift, nanoDSF thermal shift assay (TSA), GCI (Grating Coupled Interferometry)
Get binding affinity (K_D) with TRIC (MST), Spectral Shift, ITC (Isothermal Titration Calorimetry), GCI
Get binding kinetics (k_on, k_off, K_D) with GCI
Get molecular analytics parameters of proteins with DLS (Dynamic Light Scattering; r_h, PDI), nanoDSF (Differential Scanning Fluorimetry; T_m, T_agg)
Get molecular analytics parameters of proteins with HPLC (SEC MALS (Size Exclusion Chromatography), HIC (Hydrophobic Interaction Chromatography), IEX (Ion Exchange Chromatography); size, homogeneity, molecular weight, oligomerization state,  hydrophobicity, isoelectric point)
