1. Sample Preparation:

• Collect human samples (serum, plasma, cell culture supernatant, etc.) and transfer them to clean tubes.
• Centrifuge the samples at a suitable speed and duration to remove any debris or particles.
• Transfer the clarified supernatant to new tubes and store on ice until ready for analysis.

2. Kit Preparation:

• Allow the kit components to reach room temperature (RT) before use.
• Prepare the necessary reagents, including the standard solutions and working dilutions of the detection antibody and enzyme conjugate as specified in the kit's user manual.
• Dilute the samples if necessary according to the recommended range provided in the manual.

3. Plate Setup:

• Remove the desired number of coated microplate strips from the kit, leaving the remaining strips in the provided resealable bag with desiccant to maintain their integrity.
• Label the plate wells according to the sample and standard identification.
• Add the diluted samples, standards, and appropriate controls to the designated wells in duplicate or triplicate, following the plate layout provided in the manual.
• Cover the plate with an adhesive strip and gently shake or tap the plate to ensure thorough mixing.

4. Antibody Incubation:

• Incubate the plate at a suitable temperature and duration, typically at RT or 37°C, as specified in the manual.
• Add the detection antibody to each well and gently mix.
• Incubate the plate while protected from light, allowing the antibody to bind to the captured IL-1 beta.

5. Washing:

• Carefully remove the adhesive strip from the plate.
• Wash the plate wells thoroughly with the provided wash buffer, following the recommended number of wash cycles and duration specified in the manual.
• Completely remove the wash buffer from the wells by gently tapping the plate upside down on a clean absorbent material.

6. Substrate Addition and Measurement:

• Add the enzyme conjugate to each well and gently mix.
• Incubate the plate again while protected from light, allowing the conjugate to bind to the IL-1 beta-antibody complex.
• Add the substrate solution to each well and incubate for a suitable duration to allow color development.
• Stop the reaction by adding the stop solution to each well.
• Measure the absorbance of each well using a microplate reader at the appropriate wavelength specified in the manual.

7. Data Analysis:

• Use the absorbance values obtained from the standard curve to calculate the IL-1 beta concentrations in the samples, following the instructions provided in the manual.
• Analyze the data statistically using appropriate software or methods.

This general protocol provides a broad overview of the steps involved in using the Human IL-1 beta ELISA Kit. It is crucial to consult the specific instructions and recommendations provided by the manufacturer to ensure accurate and reliable results.
