Provides precise and accurate quantification of IL-6 levels, critical for both research and clinical diagnostics.

2.High Sensitivity and Specificity:

The assay is designed to detect IL-6 with high sensitivity, allowing for the detection of low concentrations.
Exhibits minimal cross-reactivity with other cytokines, ensuring specific measurement of IL-6.

3.User-Friendly Protocol:

The kit includes all necessary reagents and detailed instructions, making it accessible for both novice and experienced users.

4.Wide Sample Compatibility:

Suitable for a range of human samples, including serum, plasma, and cell culture supernatants.

5.Rapid and Reliable Results:

The entire assay can be completed within a few hours, providing timely results for urgent analyses.


Components of the Kit

Pre-coated 96-well ELISA Plate:
Wells pre-coated with monoclonal antibodies specific to human IL-6.

IL-6 Standards and Controls:
Pre-diluted IL-6 standards for generating a standard curve and quality controls to ensure assay accuracy and reliability.

Detection Reagents:
Includes biotinylated anti-IL-6 detection antibodies and streptavidin-HRP (Horseradish Peroxidase) conjugate.

Substrate Solution:
TMB (3,3',5,5'-Tetramethylbenzidine) substrate for color development.

Stop Solution:
Typically a sulfuric or phosphoric acid solution to halt the enzymatic reaction.

Wash Buffer and Dilution Buffer:
Buffers for washing the plates and diluting samples or reagents as needed.


Detailed Assay Procedure

1.Sample Preparation:

Collect human biological samples (serum, plasma, or cell culture supernatants) and filter or centrifuge to remove any particulate matter.


2.Plate Preparation:

Add IL-6 standards, controls, and prepared samples to the pre-coated wells.


Incubate the plate to allow IL-6 in the samples to bind to the immobilized antibodies on the plate.


Add biotinylated anti-IL-6 detection antibody followed by streptavidin-HRP, and incubate to form the antibody-antigen complex.

5.Substrate Addition:

Add TMB substrate to the wells and incubate to develop a colorimetric signal proportional to the amount of IL-6 in the samples.

6.Reaction Termination:

Add stop solution to halt the reaction, changing the color from blue to yellow for better absorbance measurement.


Measure the absorbance at 450 nm using a microplate reader. The intensity of the color is directly proportional to the IL-6 concentration.

Rapid and sensitive detection of interleukin-6 in serum via time-resolved lateral flow immunoassay

Applications in Research and Clinical Diagnostics

1.Inflammatory and Autoimmune Diseases:

Measurement of IL-6 is crucial in studying inflammatory diseases like rheumatoid arthritis, lupus, and inflammatory bowel disease.

2.Cancer Research:

IL-6 levels are often elevated in various cancers, including lymphoma, breast cancer, and prostate cancer. Monitoring IL-6 can aid in understanding tumor progression and treatment efficacy.

3.Infectious Diseases:

IL-6 is a key marker in the body’s response to infections, including viral, bacterial, and fungal infections.

4.Therapeutic Monitoring:

Used to monitor patients undergoing therapies that target IL-6 pathways, such as monoclonal antibodies against IL-6 or its receptor.

5.Basic Research:

Facilitates studies on cytokine biology, immune regulation, and the molecular mechanisms underlying various diseases.


The MF-Human IL-6 (Interleukin 6) ELISA Kit is an invaluable tool for researchers and clinicians, providing a reliable, sensitive, and specific method for measuring IL-6 in human samples. By offering detailed and accurate insights into IL-6 levels, this kit supports a wide range of applications from basic research to clinical diagnostics and therapeutic monitoring, ultimately contributing to the advancement of knowledge and treatment in various medical fields.
