Immune Escape, or immune evasion, refers to the process by which pathogens, tumor cells, and other disease-causing factors use various strategies to avoid detection and elimination by the immune system. In pathogens, this mechanism includes antigen variation, escape mutations, and suppression of innate or adaptive immune functions, ultimately preventing the host immune system from recognizing and eliminating the invader. In tumors, cancer cells achieve immune evasion by downregulating antigen presentation, activating immune checkpoint pathways (such as PD-1/PD-L1), secreting immune-suppressive factors (such as TGF-β), and remodeling the tumor microenvironment. These mechanisms allow cancer cells to proliferate and metastasize while avoiding immune system clearance.

Drug Screening and Efficacy Monitoring
Detecting immune evasion molecules to quickly assess the intervention effects of candidate drugs on relevant pathways, assisting with the full process of drug development.
| Panel | Example Marker Combination | Target Application | Possible Sample Preparation |
| Panel A (Checkpoint Molecules) | PD-L1, PD-1, CTLA-4, LAG-3, TIM-3, TIGIT, B7-H3, B7-H4 | - Investigate checkpoint-mediated immune suppression in tumors - Evaluate escape from immunotherapy (anti-PD-1, anti-CTLA-4) | - In vitro: Supernatants or lysates from tumor cell lines or T cell co-cultures - In vivo: Serum (soluble forms), tumor/tissue lysates from animal models or patient biopsies (if feasible) |
| Panel B (Immunosuppressive Cytokines & Enzymes) | IL-10, TGF-β, IL-35, IDO, Arg1 | - Profile immunosuppressive microenvironment - Identify cytokine-driven T cell dysfunction, Treg/MDSC expansion | - In vitro: Culture supernatants from T cells + tumor cells or DCs, after stimulation - In vivo: Serum or tumor microenvironment fluid, ex vivo restimulation supernatants |
| Panel C (Treg & MDSC Markers) | FoxP3, CD25, CD127 (Tregs), CD11b, Gr-1, CD14, CD15, S100A9 (MDSC-related) | - Quantify suppressive cell types (Tregs, MDSCs) in tumors or chronic infection sites - Evaluate mechanisms of immune evasion by these cell populations | - In vitro: Lysates from sorted Treg or MDSC cultures; supernatants if measuring secreted factors (e.g., S100A9) - In vivo: Tissue homogenates (tumor, spleen, LN), PBMC lysates, or serum for soluble markers, if present |
Efficient Multi-Parameter Detection
The protein array platform supports simultaneous detection of multiple immune-related targets, like immune checkpoint molecules (PD-L1, TIM-3), antigen presentation molecules (MHC-I), and immune regulatory factors (TGF-β, IL-10), significantly enhancing experimental efficiency. Its high-throughput detection capability enables the handling of large sample volumes in a single experiment, suitable for large-scale screening and frequent experimental applications.
Outstanding Sensitivity and Precision
Combining laser confocal imaging and near-infrared fluorescence labeling technology, our microarrays can precisely detect low-abundance molecules with picomolar sensitivity, while optimizing the chip surface to ensure high specificity to target molecules, significantly reducing background noise and ensuring data accuracy.
