Immunological & Cell-Based Assays

Our cell-based assays deliver a comprehensive biological readout of how materials or therapeutic candidates perform in a biological environment. Immunological and cell-based assays evaluate cellular behavior, immune response, cytokine signaling, biomarker expression, and functional activity in response to biomaterials, therapeutics, devices, coatings, and engineered systems. These assays provide essential insights into biocompatibility, toxicity, inflammation, immunomodulation, therapeutic performance, and biological function, supporting both early-stage R&D and regulatory submissions.

These methods encompass immune cell activation profiles, cytokine release, macrophage polarization, cytotoxicity, proliferation, migration, phagocytosis, functional cell assays, and cellular interaction testing, providing a comprehensive biological readout of how materials or therapeutic candidates perform in a biological environment.

Materials Metric offers a full suite of immunological and cell-based assays including ELISA, multiplex cytokine assays, functional cellular assays, flow cytometry, and targeted immunoassays constructed to support developers in biomaterials, medical devices, pharmaceuticals, regenerative medicine, tissue engineering, and antimicrobial technologies.

Frequently Asked Questions

What are immunological and cell-based assays?

Immunological and cell-based assays use antibodies or living cells to detect and measure biological activity, such as target binding, cellular responses, or immune function. Materials Metric performs and develops these assays to characterize biological samples, materials, and compounds. They provide functional and marker-based biological readouts.

What do immunological and cell-based assays measure?

They measure endpoints such as antigen or antibody levels, cytokine release, cell viability and proliferation, activation or inhibition responses, and other functional cellular effects. The specific readout depends on the assay format, such as ELISA or cell-based response assays. Results are reported with appropriate controls.

What sample is required for immunological and cell-based assays?

We accept biological samples such as supernatants, extracts, serum-type fluids, or test articles applied to cells, depending on the assay. Supply samples with handling and storage information and any reference controls. Share the target or response of interest so the assay can be selected or designed.

Which standards or best practices apply to immunological and cell-based assays?

Assays use validated, fit-for-purpose methods with defined controls and acceptance criteria, aligned with GLP and good cell culture practice, and with method validation principles such as ICH Q2 applied where relevant. For material evaluation, endpoints can align with ISO 10993 where applicable. Standards are cited only where genuinely relevant.
