At Precision for Medicine, our flow cytometry specialists can help develop complex multicolor panels using conventional or spectral flow cytometry. Through the characterization of the immune response, flow cytometry as a tool for immune surveillance can facilitate the identification of biomarkers and exploration of immune correlates in immunotherapy trials.

Flow cytometry has enabled clinical trial development with cell identification and characterization, allowing for the simultaneous interrogation of multiple targets on various cell subsets from limited samples. To ensure the integrity of flow cytometry test specimens generated by global clinical trials, we have a worldwide network for PBMC and sample processing, logistics, and biostorage, and multiple specialty lab facilities in the US and in Europe.

Spectral flow cytometry applications

High-throughput, multiplexed immunophenotyping

Detect antigens and therapeutic targets of interest with up to 64 parameters and comfortably interrogate up to 40 fluorophores simultaneously using high-dimensional spectral flow cytometry.

We provide a full range of flow cytometry assays, including:

  • Rare cell detection and quantification based on phenotype, apoptosis, or phosphorylation status
  • Receptor occupancy (RO) assays and ligand measurement
  • CAR NK-/T-cell therapy expression, characterization, persistence, and immunogenicity
  • Phospho-flow and intracellular (ICC) flow
  • Antigen-specific flow—detection and characterization, peptides, dextramers, tetramers
  • Modulation of activation and exhaustion markers
  • Immunophenotyping and absolute counting of cell subsets
  • Cytokine measurement using cytometric bead assays
  • Apoptosis/Cell cycle analysis/Histone methylation
  • Custom flow cytometry biomarker assays
  • GCP/GLP regulated assays
Customized solutions for your objectives

Collaborate with our experienced Precision for Medicine flow cytometry teams to custom design flow cytometry assays for your research and clinical studies.

What is spectral flow cytometry?

Spectral flow cytometry captures the full emission spectrum of fluorescent molecules using arrays of highly sensitive light detectors and has enabled characterization of high-parameter flow cytometry in a single sample. By measuring the full spectrum of light emissions from each cell, spectral flow cytometry can differentiate a vast combination of fluorophores, increasing flexibility in application design and enabling the development of complex multicolor panels for comprehensive immunophenotypic analysis by flow cytometry.

Cytek® Aurora 5-laser

The Cytek Aurora leverages full-spectrum technology to provide high-resolution data at the single-cell level to resolve challenging cell populations, such as cells with high autofluorescence or low levels of expression of key biomarkers, regardless of assay complexity. At present, our Cytek instrument’s capabilities are

  • 64 parameters
  • 5 lasers (355, 405, 488, 561, 640nm)
