In Vivo Immunophenotyping via Flow Cytometry

Flow cytometry is the tool of choice to determine the immunomodulatory action of new immunotherapeutics during animal testing. Our large suite of cell line-derived and mouse-derived syngeneic tumor models allows the testing of immunotherapeutics with various modes of action.

Features of our flow cytometry service:

  • We employ a designated team of scientists with rich experience in flow cytometry and cell sorting applications
  • A suite of state-of-the-art flow cytometers and cell sorters covering all flow cytometry needs
  • Four ready-to-go staining panels are available for immune phenotyping with multiplexing of up to 20 immune cell markers
  • Panel customization and de novo panel developments are an option

Reach out today to discuss your project plans. We will be happy to work with you to ensure your specific research questions are being addressed to the best extent possible.

Instrumentation – Flow cytometers and Cell sorters

Our panels

We offer four staining panels for immediate immune profiling of tumor samples. Custom-tailored panels can be established upon request to detect the immune cell population of your interest.

Flow Cytometry for Immunophenotyping Setup

Clinical data indicate that only some patients respond to treatment with immune-modulating drugs. Therefore, it is essential to consider the immune response during preclinical drug development. Flow cytometry is widely used for the analysis of immune cell populations in tumors as a means to describe the immune response.

Panel: A comprehensive analysis of numerous immune cell populations in one tumor is a challenge. We use established, ready-to-use staining panels that allow for the analysis of various immune cell populations. In addition, we can custom-tailor our existing panels or establish new antibody panels to match our customer’s research needs.

Method: Primary tumor material is disrupted, erythrocytes removed, and up to 3×106 obtained single cells/well are dispensed. The single cells are stained with marker-specific fluorescent antibodies and analyzed by flow cytometry.

Report: All data of the mouse study, including tumor growth and flow cytometry data, will be presented in a comprehensive report, custom-tailored to the client study, and written by a Ph.D.-level technical writer. The analysis enables you to draw conclusions directly from the study outcome and use the data for the filing of official documents.

Add-ons: Further immunophenotyping methods are available at Reaction Biology to investigate the cytokine & chemokine concentrations in the tumor via multiplex immunoassays, to localize tumor-infiltrating immune cells via IHC, or to test the immune cell function via in vitro assays.
