What is your protocol for PNGase F treatment?

PNGase F cell treatment:
To deglycosylate a protein of interest in native conditions.

Reagents: 
PNGase F, NEB P0704L (https://www.neb.com/en-us/products/p0704-pngase-f)

1. Start with two 15 cm dishes of cells, grow to 75-80% confluence.
2. Lyse each with 250 μL 1X cell lysis buffer (Cell Lysis Buffer (10X) #9803).
3. Combine these two dishes of cells into one tube.
4. Sonicate the lysate. 
5. Set up two 1.5 mL tubes: 
 
Treated Cell Lysate:Control Cell Lysate:
240 μL cells in lysis buffer240 μL cells in lysis buffer                
30 μL 10X denaturing buffer     30 μL 10X denaturing buffer
30 μL water30 μL water

6. Heat both tubes at 95°C for 10 min.
7. Chill on ice then centrifuge for 10 sec.
8. Add the following to each tube:
 
Treated Cell Lysate:Control Cell Lysate:
60 μL 10X GlycoBuffer260 μL 10X GlycoBuffer2        
60 μL 10% NP4060 μL 10% NP40
180 μL water240 μL water
60 μL PNGase F enzyme 

The total volume in each tube is 660 μL.

9. Incubate both tubes at 37°C for 2 hr.
10. Stop the reaction by adding 330 μL 3X SDS+DTT loading buffer (Blue Loading Buffer Pack #7722). The total volume in each tube is 990 μL.
11. Heat at 95°C for 5 min prior to loading.
