描述
Peptide -N-Glycosidase F, also known as PNGase F, is an amidase that cleaves between the innermost GlcNAc and asparagine residues of high mannose, hybrid, and complex oligosaccharides from N-linked glycoproteins

实验操作流程
Standard Operating Procedure
Denaturing Reaction Conditions:
1. Combine 1-20 µg of glycoprotein, 1 µl of Glycoprotein Denaturing Buffer (10X) and H2O (if necessary) to make a 10 µl total reaction volume.
2. Denature glycoprotein by heating reaction at 100°C for 10 minutes.
3. Chill denatured glycoprotein on ice and centrifuge 10 seconds.
4. Make a total reaction volume of 20 µl by adding 2 µl GlycoBuffer 2 (10X), 2 µl 10% NP-40 and 6 µl H2O.
5. Add 1 µl PNGase F, mix gently.
6. Incubate reaction at 37°C for 1 hour.
Note: The simplest method of assessing the extent of deglycosylation is by mobility shifts on SDS-PAGE gels.
Note: To deglycosylate different glycoprotein, longer incubation time may be required.
Non-Denaturing Reaction Conditions:
1.Combine 1-20 µg of glycoprotein, 2 µl of GlycoBuffer 2 (10X) and H2O (if necessary) to make a 20 µl total reaction volume.2.Add 2-5 µl PNGase F, mix gently.
3.Incubate reaction at 37°C for 4 - 24 hours.
Note: To deglycosylate a native glycoprotein, longer incubation time as well as more enzyme may be required.
Note: The simplest method of assessing the extent of deglycosylation is by mobility shifts on SDS-PAGE gels.
