Overview

Companion diagnostics (CDx) antibodies are high-precision reagents designed to support research requiring accurate biomarker detection and monitoring. These antibodies allow researchers to explore protein expression patterns, validate targets, and develop reliable experimental assays. With high specificity, reproducibility, and versatility, CDx antibodies are ideal for studying immune responses, tumor biology, hematopoietic systems, and other biomarker-driven research areas.

Research Applications

• Biomarker Identification:

Detect and quantify specific proteins to study cell signaling, immune modulation, or tumor-associated markers. CDx antibodies help reveal correlations between protein expression and biological outcomes, enabling more precise experimental conclusions.

• Assay Development & Optimization:

Provide robust reagents for immunohistochemistry (IHC), immunofluorescence (IF), flow cytometry, ELISA, and multiplexed detection platforms. Antibodies with validated specificity reduce assay variability and improve reproducibility.

• Experimental Monitoring:

Track changes in protein expression under varying experimental conditions, including treatment, stimulation, or genetic manipulation. Reliable detection ensures meaningful interpretation of cellular and molecular responses.

• Target Validation:

Support the discovery and validation of novel biomarkers, helping researchers confirm target expression patterns, localization, and functional relevance in cells and tissues.

• Translational Research Support:

Aid in preclinical studies by providing consistent reagents to assess target biology, pathway activity, and potential therapeutic interactions.

Common Targets

CDx antibodies cover a broad range of biomarker classes:

• Immune Checkpoints: PD-1, PD-L1, CTLA-4, LAG-3, TIM-3 — for studying immune regulation and checkpoint pathways.
• Oncology-Associated Markers: HER2, EGFR, ALK, BRAF, KRAS — for research into tumor biology, signaling, and therapeutic response.
• Hematopoietic and Stem Cell Markers: CD19, CD20, CD33, CD34 — for characterization of blood cells, stem cell populations, and immune cell subsets.
• Predictive & Functional Biomarkers: BRCA1/2, MSI, MMR proteins — for research on genomic stability, DNA repair, and predictive molecular pathways.
• Custom or Novel Targets: Available upon request for research projects requiring specific or newly discovered biomarkers.

Advantages of Recombinant CDx Antibodies
