2. Apply the basic principles of immunology to determine the antigens (polypeptides and proteins) in tissue cells through chemical reactions to make the chromogenic agents (fluorescein, enzymes, metal ions, isotopes) labeled with antibodies chromogenic, and conduct localization, qualitative and quantitative research on them.
3. Make an accurate diagnosis of the disease further.
