Are there any considerations when adding protease inhibitors to the CER I and NER Reagents?
EDTA-free Halt Protease and/or Phosphatase Inhibitor Cocktails (e.g., Cat. No. 78425) can be added to CER I and NER reagents. Most commercially available protease inhibitor cocktails are also compatible; however, avoid protease inhibitors that contain alcohols. Because the concentration of the CER I and NER Reagents are critical, do not dilute these reagents by more than 5% when adding protease inhibitors.
Is the final soluble nuclear fraction dialyzable when using the NE-PER Extraction reagents?
Yes. The nuclear fraction can be dialyzed in a Slide-A-Lyzer MINI Dialysis Unit (Cat. No. 69550) against a buffer, such as PBS, that is compatible with the specific downstream application. A buffer exchange can also be performed using the Thermo Scientific Protein Desalting Spin Columns (Cat. No. 89849) or Zeba Desalt Spin Columns (Cat. No. 89882).
