Integrated Services · Multiplex IF

Multiplex immunofluorescence services

Connect multiple protein markers to the cells that express them. Start with clinically characterized FFPE tissue and TMAs from TriStar’s repository, then add multiplex immunofluorescence staining, image analysis and pathology guidance around your oncology study.

MULTIPLE MARKERS · ONE TISSUE SECTION

Study protein expression in its cellular context

Multiplex immunofluorescence (mIF) uses antibody-based fluorescent staining to detect multiple protein targets within the same tissue section. It can connect marker co-expression with cell identity and location, helping you investigate the tumor microenvironment while retaining tissue architecture.

Marker co-expression

Examine whether selected targets are detected in the same cells, using the marker combinations defined for your study.

Immune-cell phenotyping

Investigate immune populations alongside tumor cells and the surrounding tissue.

Tumor and stromal compartments

Compare the distribution of marker-positive cells across the tissue regions relevant to your question.

Treatment-defined comparisons

Connect tissue measurements with the treatment history, response and follow-up fields available for the selected cohort.

PLAN THE ASSAY AROUND THE QUESTION

From tissue selection to multiplex analysis

Define the cohort, marker panel and analysis together. The platform, marker compatibility and reporting scope are confirmed for each project.

01 · TISSUE & COHORT

Select the study material

Review indication, histology, treatment groups and available donor records. Consider tissue morphology, the regions of interest and how much material is needed for controls and study testing.

02 · PANEL & STAINING

Define the marker combination

Discuss the proteins and cell populations you need to resolve, with antibody compatibility, controls and tissue autofluorescence considered in assay planning. An optimized single-marker IHC assay does not automatically establish performance in a multiplex panel.

03 · IMAGING & READOUTS

Agree the measurements

Scope imaging and analysis around the study question: marker-positive cell counts, co-expression, tissue compartments or spatial relationships. Confirm phenotype definitions, reporting units and pathology review before analysis.

FFPE SECTIONS & TISSUE MICROARRAYS

Start with the tissue and clinical context your study needs

Select materials for the biological comparison, then assess suitability for the proposed multiplex assay. Existing molecular data, additional staining and clinical-field coverage are reviewed separately.

COHORT SCREENING

Tissue microarrays

Compare selected markers across multiple donors using defined tissue cores. Plan core location and replication around heterogeneity; a core samples only part of a tumor and may need whole-section follow-up.

REGIONAL CONTEXT

FFPE whole-tissue sections

Retain a broader view of tissue architecture when tumor borders, stromal regions or local immune organization are central to the study. Discuss available blocks and section requirements for the selected cohort.

STUDY PLANNING

Multiplex immunofluorescence questions

How is multiplex immunofluorescence different from IHC?

Both use antibodies to study proteins in tissue. Conventional chromogenic IHC commonly assesses a target with a visible stain; multiplex IF uses fluorescent labels to distinguish several targets in the same section. Choose the method around the marker combination, localization question and required analysis.

Can FFPE tissue and TMAs be used for multiplex IF?

Yes, multiplex IF can be applied to FFPE tissue sections and tissue microarrays. Suitability depends on the tissue, fixation, antigen preservation and proposed panel. TriStar reviews repository material and assay requirements together rather than assuming every block or array is suitable.

Which markers and how many targets can I include?

Share your proposed markers and the cell populations you want to distinguish. The compatible marker combination, platform, controls and achievable panel size need project-specific review. TriStar’s IHC assay library is a starting point for a discussion, not a list of pre-validated multiplex panels.

How does multiplex IF relate to digital spatial profiling?

Multiplex IF produces fluorescence images that can resolve protein expression and cell phenotypes in tissue. Region-based digital spatial profiling, such as GeoMx, measures selected protein or RNA targets in defined regions. The approaches address different readout needs; discuss the biological question before selecting a method.

What should I include in an inquiry?

Include your cancer indication, cohort or treatment groups, approximate sample count, preferred tissue format, marker list and analysis goals. Indicate the clinical or molecular data you need and whether you are interested in repository tissue, additional assays or both. These details help define feasibility and a project-specific scope.
