Immunofluorescence Protocol of Staining on Frozen Sections

1. Place sections at room temperature for 10 minutes.

2. Incubate the sections with Fixation Buffer at room temperature for 10 minutes.

3. Wash the sections with PBS 5 minutes × 3 times in a washing box.

4. Incubate the sections with Antigen Retrieval Buffer at room temperature for 5 minutes.

5. Wash the sections with PBS Buffer 5 minutes × 3 times in a washing box.

6. Immerse the sections with Permeabilization Buffer at room temperature for 10 minutes.

7. Wash the sections with PBS Buffer 5 minutes × 3 times in a washing box.

8. Incubate the sections with Blocking Buffer at room temperature for 1 hour.

9. Incubate the sections with different antibodies in Primary Antibody Dilution Buffer at 4 °C overnight.

10. Wash the sections with PBS Buffer 5 minutes × 3 times in a washing box.

11. Incubate the sections with Fluor-conjugated secondary antibodies in Secondary Antibody Dilution Buffer at room temperature for 2 hours.

12. Wash the sections with PBS Buffer 5 minutes × 3 times in a washing box.

13. Rinse sections to be mounted with distilled water.

14. Tap the sections and then touch the edges of section on a paper to remove water.

15. Drop the top of sections with Mounting & Antifade Buffer with DAPI (Do Not Touch Tissue).

16. Detect with confocal microscope Or Store the slice in the dark at 4 °C.
