  1. Sample Preparation:

    • Collect the mouse tissue or cell culture supernatant.
    • Centrifuge the samples at a high speed to remove cell debris.
    • Transfer the clear supernatant to a fresh tube and store on ice.
  2. Protein Extraction:

    • Add a lysis buffer containing protease inhibitors to the samples.
    • Incubate the samples on ice for 30 minutes to allow complete lysis.
    • Centrifuge the lysates at a high speed to pellet insoluble material.
    • Transfer the supernatant to a new tube and keep on ice.
  3. Protein Quantification:

    • Measure the protein concentration in the supernatant using a protein quantification assay, such as the Bradford or BCA assay.
    • Adjust the protein concentration to a desired working concentration using lysis buffer or other appropriate diluents.
  4. Western Blot Analysis:

    • Prepare the protein samples by mixing them with an appropriate sample buffer and heating at 95°C for 5 minutes.
    • Load the samples onto a polyacrylamide gel and perform SDS-PAGE.
    • Transfer the separated proteins onto a PVDF or nitrocellulose membrane using a semi-dry or wet transfer system.
    • Block the membrane with a blocking buffer to prevent non-specific binding.
    • Incubate the membrane with a primary antibody specific to Mouse IFN-gamma protein at the recommended dilution overnight at 4°C.
    • Wash the membrane to remove unbound primary antibody and incubate with a secondary antibody conjugated to an enzyme, such as HRP.
    • Visualize the protein bands using an appropriate detection method, such as chemiluminescence or colorimetric detection.
  5. ELISA Assay:

    • Coat a microplate with a capture antibody specific to Mouse IFN-gamma protein.
    • Block the plate with a blocking buffer to prevent non-specific binding.
    • Add the prepared protein samples and standards to the wells and incubate for a specific period at room temperature.
    • Wash the plate to remove unbound proteins and add a detection antibody specific to Mouse IFN-gamma protein.
    • Incubate the plate for a specific period at room temperature.
    • Wash the plate again and add a substrate solution that generates a detectable signal.
    • Measure the absorbance or fluorescence of each well using a microplate reader.
    • Determine the concentration of Mouse IFN-gamma protein in the samples using the standard curve.

This protocol provides a general guideline for working with Mouse IFN-gamma protein. It is recommended to consult the specific product manual or literature for the Mouse IFN-gamma protein kit you are using, as the protocol may vary slightly depending on the manufacturer's instructions and the specific assay requirements.
