What we do

The Immune Analysis Facility (IAF) at Roswell Park Comprehensive Cancer Center is responsible for serial monitoring of immunologic functions in patients with cancer, patients treated with biologic therapies, and patients participating in clinical trials or research protocols at Roswell Park and external institutions and hospitals.

The development of immune monitoring assays is essential to determine the immune responses in patients receiving novel immunotherapies and ultimately transitioning these therapies from the clinical trial phase to standard of care. The IAF offers a broad range of state-of-the-art immunologic assays utilizing multiple platforms to support novel investigator-initiated immunotherapy trials.

Offering the latest immunomonitoring technology

We are committed to continuously expanding access to unique technologies and the use of advanced instrumentation and assisting with experimental design and analysis. As advances in immunobiology occur we will perform pre-clinical evaluations of new assays requested and add them to the available assay list if deemed reliable and standardized.

The IAF offers consultation regarding optimal immunologic assessment and assay development for innovative approaches to evaluate immune responses. We provide expert advice regarding the types of assays for immunomonitoring and data interpretation tailored to fit the endpoints of each specific clinical trial.

Request a service

Interested investigators are asked to provide a summary of their clinical trial design, which will be reviewed by IAF in order to design the appropriate methodology to successfully measure the endpoints of the study.

Services & fees

The Immune Analysis Facility offers a full complement of services designed to monitor patients’ immunological function during cancer treatment to support clinical and translational studies:

We will separate, aliquot and cryopreserve peripheral blood mononuclear cells (PBMC) and serum/plasma from whole blood by Ficoll gradient centrifugation. Serum-free cryopreservation medium is suitable for determining antigen-specific response following freeze/thaw and for long-term storage in liquid nitrogen freezer. Separation of mononuclear cells from any specimens, e.g. fluid, lymph node or spleen, can be performed.

Single-cell suspension from solid tumor tissue is prepared by mechanical dissociation with and without enzyme digestion.

This assay is used to measure the antibody titer specific to cancer antigens. The serially diluted serum or plasma from cancer patients are added in an ELISA plate coated with recombinant protein antigens.

The antibody bound to proteins is detected by utilizing enzyme-labeled anti-human IgG-specific antibody and fluorescent substrate.

In addition to measurement of autoantibodies, commercially available kits can be used for the detection of cytokine and chemokine levels in serum, plasma, fluid or tissue culture supernatants.

The Ella system is a next generation hands-free and high-performance immunoassays, allowing researchers to acquire highly reproducible validated assay data with very few manual steps, which is the only self-contained testing platform for the simultaneous execution of multiple ELISA-based immunoassays.

The assay volume required is 25 μl or less for up to 4-plex customized assays and the data is ready in two hours from sample prep.

MAGPIX system is the new affordable, compact and cost-effective Luminex fluorescent detection system suitable for medium-throughput multiplex immunoassays.

The system immobilizes beads with magnetic force, excites them using light-emitting diodes (LEDs), and detects beads and analytes using a CCD camera.

The system can read up to 50 unique magnetic bead regions simultaneously in each well of a 96-well plate.

This assay is used to detect and quantify the number of T cells that secrete a particular cytokine (e.g. Interferon-γ) upon recognition of a specific antigen.

T cells are cultured with antigen-presenting cells in wells coated with an antibody recognizing a particular cytokine. The coating antibody captures the secreted cytokine and a second cytokine-specific antibody is coupled to a chromogenic substrate and used for detection. Results appear as spots, with each spot corresponding to one cytokine-secreting cell. The number of spots equals the number of cytokine-secreting cells for a specific antigen.

This assay does not determine the amount of cytokine secreted. This assay is highly sensitive (1 cell in 100,000) and can be performed directly ex-vivo using relatively few T cells.

Seahorse XFe96 extracellular flux analyzer tracks and records the oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) that reflects mitochondrial respiration and glycolysis in real-time in 96-well plate format.

Validated assays include the glycolysis stress test, cell mito stress test, mito fuel flex test, glycolytic rate assay, ATP rate assay, cell energy phenotype test and fatty acid oxidation measurement. Custom-made assays are also available.

Helios/CyTOF, a time-of-flight mass cytometry, is capable of acquiring single cell suspension labeled with transition metal isotopes-conjugated monoclonal antibodies.

The main advantages of mass cytometry over conventional fluorescence-based flow cytometry are minimal spectral overlap of each parameter, thereby, the CyTOF can theoretically detect up to 135 isotopes without compensation.

In addition, since the metal isotopes used for conjugation are rare in biological samples and the environment, it can detect the specific signal of each protein on individual cells regardless of autofluorescence.

Currently this system allows single cell analysis with up to 42 parameters for phenotype and function.

Hyperion Image Mass Cytometer (IMC) is a high-resolution laser ablation system for 1 m cellular resolution, allowing the most comprehensive analysis of the immune and non-immune contexture in the tumor microenvironment.

The IMC module uses the CyTOF instrument to detect up to 40 markers simultaneously on a tissue slide and far exceeds the capabilities of any multi-spectral IHC system that currently exists, by measuring the abundance of metal isotopes tagged to antibodies.

More than 100 metal isotopes tagged antibodies for the IMC are now commercially available for immunocytometry and immunohistochemistry analyses. Custom antibody conjugation is available within the Immune Analysis Facility. Staining tissue with antibodies will be conducted within the facility or researcher’s lab.

The Isolight analyzer from Isoplexis is the newest addition to our facility.  This benchtop system performs automated highly mutliplexed live single cell secretome analysis, single cell highly multiplexed phosphoproteomic and metabolic analysis as well as bulk/population protein analysis all on one platform and in a single workflow. Fully analyzed data is received on the same day. IsoLight is ideal for comprehensive profiling of the secretory capabilities of different cell types and of cells at different developmental or treatment stages.
