No project is too big or too small. We offer industry competitive pricing, unmatched turnaround times, and personalized project management with no cookie cutter solutions.

Surface Plasmon Resonance (SPR)

SPR is a high-throughput technique that measures the kinetics of biomolecular interactions, including those of fragments & small molecules. The Gold Standard of biophysics.

Isothermal Titration Calorimetry (ITC) & Differential Scanning Calorimetry (DSC)

ITC is a truly label-free, steady-state technique to directly determine the thermodynamic parameters of biomolecular interactions. An excellent orthogonal complement to SPR.

Bio-Layer Interferometry (BLI)

BLI is a high-throughput kinetic screening technique that can measure biomolecular interactions of proteins, peptides, and nucleic acids in complex matrices and without microfluidics.

Nuclear Magnetic Resonance (NMR)

NMR spectroscopy can be used for both biosimilar comparability & QC, in addition to fragment screening and affinity titration studies.

Plate-Based Assays

Ichor has the capability to conduct a variety of quantitative plate based assays, including ELISAs and various fluorescence experiments (e.g. FRET & anisotropy).

SPR is our speciality!

Assay development, high-throughput fragment and small molecule screening, & kinetic or affinity characterization

We have both Biacore 8K and 8K+ SPR systems, the state of the art

  • High-throughput SPR screening: kinetic screening & characterization
  • Clean, binding level, & affinity screens
  • Epitope binning
  • Concentration & potency analysis
  • Personal one on one discussion of data and results with a Ph.D. scientist; we stand by our data

Assay development & Target Validation: Feasibility and full control characterization

Fast turnaround, most projects are initiated within 1-2 weeks upon receipt of materials.

Full ownership, client retains full ownership of all raw and processed data and is entitled to Excel exports and a PowerPoint presentation of data and results.



We have invested heavily in facilities, state of the art capital equipment, and highly trained personnel so you don’t have to!

Molecular Devices SpectraMax i3x

Our temperature controlled plate reader is equipped with an automated high-throughput StakMax and can work with 96- or 384-well plates in absorbance, fluorescence, or chemiluminescent read modes.


TA Instruments nano-ITC & nano-DSC

The nano-series instruments only require a fraction of the protein quantity that earlier models consumed.

Our biophysics projects have fast turnaround times

Most biophysics projects start within 2 weeks of receipt of materials.


Please reach out to us with any questions or comments, we are here to help you.

All projects are managed by PhD level scientists and most projects start within 1-2 weeks of receipt of all test articles, samples, reagents, and consumables. We take pride in our work and pay attention to details during the execution. At the conclusion of your project, all data and reagents are yours. You can expect to receive a PowerPoint slide deck containing all relevant conditions and data as a project deliverable, in addition to all raw data.

Our view of customer service demands that all projects receive the dedicated attention, research, and scoping they deserve to be properly and fully quoted and executed at the highest scientific standards. We also believe in being respectful of everyone’s time. We therefore require all prospective clients to attend a brief teleconference to discuss their projects before a quote can be issued. Out quotes are custom-built and tailored to your specific project.

No project is too small for us. We are here to help solve your problems and we see ourselves as your lab down the hall.
