Answer

The HeLa ICC/IF on the datasheet was produced as follows.

1. Culture cells on coverslips. (Chamber slides are an alternative).

2. Fix with 500 ul pre-cooled methanol, -20C, for 5 minutes.

3. Wash with PBS twice, 3 minutes per wash.

4. Block non-specific protein interactions with 500 ul of 2.5% BSA/PBS for 30 minutes.

5. Remove blocking solution (washing is not necessary) and add the Erp72 antibody, 200 - 400 ul, diluted 1/500 in 2.5% BSA/PBS. Incubate for 1 hour at RT or 4C overnight (recommended).

6. Wash 3X with PBS for 3 minutes per wash.

7. Add 200 - 400 ul secondary anti-rabbit Igg, conjugated to the fluorchrome of choice, for instance, ab150073,

8. Incubate at RT for 60 minutes.

9. Wash 3X with PBS for 3 minutes per wash.

10. Counterstain if desired (e.g., DAPI nuclear counterstain), and mount coverslips with anti-fading mounting medium, for instance, ab104135 or ab104139 (contains DAPI, so there is no need to counterstain beforehand).
