Detect and measure a protein

Get protein out of cells, measure it, separate it by size and detect the one you care about.

  1. Break the cells open while keeping the protein, and its modifications, intact.

  2. Measure total protein so every lane or well gets the same amount.

  3. SDS-PAGENot started

    Separate proteins by size so a single band can be identified.

  4. Western blotNot started

    Transfer the gel to a membrane and detect the target with an antibody.

  5. ELISANot started

    Measure the protein's concentration accurately across many samples at once.
