Tissue & biomarker data for ADC and bispecific research

Explore target expression in clinically characterized tissue for antibody-drug conjugate (ADC) and bispecific T-cell engager programs. Access existing biomarker datasets or add IHC and pathology support to selected TMAs and FFPE cohorts.

Tissue selection for antibody research

Build your study around target expression

01

ADC target expression

Compare prevalence and expression levels

Explore expression across tumor types and subtypes, including staining intensity, proportion of positive cells and tissue distribution.

02

Bispecific research

Assess tumor targets and immune context

Select tissue to examine tumor-associated targets alongside immune markers. Add the assays and pathology review appropriate to your research question.

Existing IHC datasets

Compare ADC-related targets in breast and lung cancer

IHC assays run on serial TMA sections connect target-level scores and images with available standard-of-care outcomes. The existing work includes hormone receptor-positive and triple-negative breast cancer, and lung adenocarcinoma and squamous cell carcinoma.

Marker coverage, images and clinical fields are dataset-specific. Serial-section comparisons do not establish same-cell co-localization.

Selected arrays

TMAs for target-expression studies

Survey tumor and non-malignant tissues, compare treatment groups or select an array with existing molecular characterization. These are tissue options for study planning; they do not all include the ADC-marker dataset described above.

Counts are approximate. Product details and datasheets describe tissue composition, available data and assay suitability.

Different tissue questions for ADCs and bispecifics

Select the tissue and readouts around the therapeutic mechanism being investigated, while keeping expression characterization distinct from functional testing.

01

ADC target characterization

Compare tumor-antigen expression across indications, molecularly defined subgroups and nonmalignant tissues. IHC can help describe staining intensity, the proportion of positive cells and distribution within the selected tissue. Discuss whole sections when heterogeneity is central to the question, and specify the scoring and image outputs needed.

02

Bispecific T-cell engager context

Evaluate the tumor target alongside T-cell markers and the surrounding immune context. Define whether you need comparisons across cases, tissue regions or cellular neighborhoods. Serial sections support comparisons between nearby sections; a same-cell or spatial co-localization question requires an appropriate assay and analysis plan.

03

Interpret the available evidence

Linked standard-of-care treatment and follow-up records provide clinical context; they are not evidence of response to an investigational ADC or bispecific. FFPE expression studies do not establish target internalization, payload activity, T-cell killing or clinical safety. These questions require separate functional or clinical evidence beyond the tissue characterization described here.

Explore target-expression prevalence studies for cohort design and immuno-oncology research for immune-cell and treatment context.
