Unlocking Cytokine Detection: Pre-Conjugated Antibody Pairs for Critical Research
Detecting cytokines at ultra-low levels is essential for understanding immune response, inflammation, and disease progression. However, for many researchers, the reliable detection of low-abundance targets, such as IL-4, IL-6, and TNF-α, remains challenging with standard methods.
Cavidi’s new pre-conjugated antibody pair kits change that equation. Optimized for our BOLD-enabled Exazym® platform, these kits deliver ultrasensitive detection without specialized equipment or workflow changes, while dramatically simplifying assay development.
IL-6: The Inflammation Sentinel IL-6 serves as a critical biomarker in COVID-19, sepsis, and autoimmune diseases. Yet standard ELISA methods often struggle with clinically relevant concentrations. Our IL-6 Antibody Pair Kit delivers high sensitivity and reproducibility, making it easier to track subtle immune responses in infection models, drug trials, and patient samples where every picogram matters.

IL-4: Unlocking Allergy and Immunotherapy Research IL-4 drives Th2-mediated immune responses and serves as a key biomarker in asthma, allergy, and immunotherapy research. We recently demonstrated 50X sensitivity improvement using our IL-4 pair with Exazym, pushing detection well into the femtogram-per-milliliter range. This breakthrough opens new possibilities for studying early allergic responses and therapeutic interventions.

TNF-α: Precision for Autoimmunity and Oncology TNF-α regulates inflammation, autoimmune pathology, and tumor microenvironment dynamics—making it indispensable for therapeutic monitoring and disease progression studies. Our TNF-α Antibody Pair Kit enables ultra-low-level detection critical for capturing transient or low-grade inflammatory responses that standard assays miss.

Why Pre-Conjugated Matters
Time is precious in research. Our pre-conjugated pairs eliminate days of optimization work and reduce variability—they’re ready to run with Exazym® for ultrasensitive detection with minimal startup time.
Whether you’re validating therapeutic targets, tracking disease progression, or pushing assay performance limits, these kits offer a fast, reliable, scalable solution.
The Bottom Line: Don’t let sensitivity constraints limit your cytokine research. These three kits represent the most critical inflammatory markers across infectious disease, allergy, and autoimmunity research—with the ultrasensitivity BOLD delivers.
