Immunofluoresent staining of cells in culture Important notes: 1. 2. 3. 4. 5. Use sterile cover glasses only. All washes and incubations take place in a 24-well plate. All washes are performed in a 500μl volume. Blocking is performed in a 200μl volume. Antibody incubations are performed in a 160μl volume. Staining: 1. Fix cells in 1:1 Acetone;Methanol for 10min at R.T with gentle shaking. 2. Wash in PBS for 30-60sec. 3. Wash in 0.025% Triton X-100 in PBS 3x 5min with gentle shaking (250μl Triton into 1L PBSx1). 4. Block in 3% normal goat serum in PBS for 1h at R.T (300μl normal goat serum into 10ml PBSx1). 5. Discard blocking solution. 6. Add primary antibody diluted in 3% normal goat serum in PBS. 7. Incubate 1h at R.T or O.N at 4C. 8. Wash in 0.025% Triton X-100 in PBS 3x 5min with gentle shaking 9. Add secondary antibody diluted in 3% normal goat serum in PBS. 10. Incubate 1h at R.T. 11. Wash in 0.025% Triton X-100 in PBS 3x 5min with gentle shaking. 12. Dry cover glasses as much as possible. 13. Add 10μl ready to use DAPI + mounting to a slide, put the cover glass on the slide (cells facing downwards to the slide). 14. Slides can be kept at 4C for a few months.
