1. Prepare sterilized coverslip.
2. Put them in the tissue-culture plate.
3. Place and maintain the cell suspension in the tissue-culture dish for 24 hours until the cells are seeded onto the glass.
4. Prepare fixative with fresh 4% paraformaldehyde solution in PBS.
5. Wash coverslip twice with PBS.
6. Remove PBS but keep the specimen from drying completely.
7. Fix the specimen at room temperature by dipping in 4% paraformaldehyde solution for 10 minutes.
8. Wash twice with PBS.
9. Incubate them at room temperature in 0.1% triton x-100 or NP -40 in PBS to make them prone to infiltration. Incubation time will differ up to 15 minutes depending on the types of antigen.
10. Wash 5 minutes or longer with PBS 4 times.
11. Place the coverslip on the even surface and keep submerged for 30 minutes in 5% BSA in PBS solution for blocking.
12. Treat sufficient amount of diluted primary antibody at room temperature for an hour.
13. Wash 5 minutes or longer with PBS 3 times.
14. Treat Fluorochrome-conjugated anti-immunoglobulin antibody (labeled secondary reagent) at room temperature for 30 minutes (make sure it doesn't exceed 60 minutes).
15. Wash 5 minutes or longer with PBS 3 times.
16. After mounting using fluorescent mounting solution, keep it in the dark.
