Protein detection
Measure target proteins in biological samples using defined standards and optimized detection reagents.
Assay Kits
Immunoassay kits provide ready-to-use systems for detecting and measuring proteins, antibodies, antigens, hormones, cytokines and other biological targets through specific binding reactions. They are used in immunology, cell biology, molecular biology, biomarker research and assay development when laboratories need sensitive, reproducible and interpretable results. By combining optimized capture reagents, standards, buffers and detection systems, immunoassay kits reduce setup time and help researchers focus on sample quality, controls and biological interpretation.

Overview
Immunoassay kits are built around specific molecular recognition, usually involving antibody-antigen binding. This makes them suitable for target-focused measurements in complex biological samples such as serum, plasma, cell culture supernatant, tissue extracts or cell lysates.
Choosing the correct immunoassay depends on the target, species reactivity, sample type, detection format and expected concentration range. Researchers should also compare sensitivity, standard curve quality, required sample volume and protocol time before selecting a kit.
Applications
Measure target proteins in biological samples using defined standards and optimized detection reagents.
Detect antigen-antibody interactions in research workflows requiring specific molecular recognition.
Quantify immune mediators such as interleukins, interferons, TNF-related proteins and chemokines.
Compare target levels across treatment groups, time points or biological sample sets.
Selection guide
A good immunoassay kit should match the biological target, sample matrix and required detection sensitivity.
Check the target name, gene symbol, aliases and molecular form to avoid selecting a kit for the wrong analyte.
Verify whether the kit is validated for human, mouse, rat or another species relevant to your samples.
Confirm compatibility with serum, plasma, supernatant, lysate, tissue homogenate or other sample types.
Make sure expected sample concentrations fall inside the kit’s working range and standard curve.
Prefer kits with clear protocols, standard preparation guidance, validation data and batch documentation.
FAQ
Common questions about selecting immunoassay kits for research workflows.
An immunoassay kit is used to detect or quantify a target molecule through specific binding, often antibody-antigen recognition.
Common sample types include serum, plasma, cell culture supernatant, cell lysate, tissue homogenate and biological fluids, depending on kit validation.
An immunoassay specifically relies on immune-binding reagents such as antibodies, while general assay kits may measure enzymatic, chemical or cellular activity.
Check target specificity, species reactivity, sample type, sensitivity, standard curve range, protocol time and included controls.
