Species: Elizabethkingia miricola
Product Description: Peptide:N-glycosidase F (PNGase F) removes all N-linked glycans (high-mannose, hybrid, and complex) from glycopeptides and glycoproteins. This PNGase F, a recombinant amidase cloned from Elizabethkingia miricola, cleaves between the innermost GlcNAc and asparagine residues. Protocols for both denaturing and non-denaturing conditions are shown in the "Application Note" section.
One vial of GTX141281-pro contains 75000 units (75kU) PNGase F.
Application Note:
One unit is defined as the amount of enzyme required to remove > 95% of the carbohydrate from 10 µg of denatured RNase B in 1 hour at 37°C in a total reaction volume of 10 µl.
Protocols for both denaturing and non-denaturing conditions:
Reaction buffer (not included; must be prepared by user):
- Buffer 1 (5% SDS, 0.4 M DTT)
- Buffer 2 (0.5 M Sodium Phosphate, pH 7.5)
- 10% IGEPAL® CA-630
Denaturing conditions:
- Combine 10-20 µg of glycoprotein, 1 µl Buffer 1 (5% SDS, 0.4 M DTT), and H2O to a total volume of 10 µl.
- Denature glycoprotein by heating at 100°C for 10 minutes.
- Cool glycoprotein on ice.
- Add 2 µl Buffer 2 (0.5 M Sodium Phosphate, pH 7.5), 2 µl 10% IGEPAL® CA-630, 2 µl PNGase F and H2O to a total volume of 20 µl.
- Incubate at 37°C for 1 hour.
- Analyze by SDS-PAGE.
Non-denaturing conditions:
- Combine 10-20 µg of glycoprotein, 1 µl Buffer 2 (0.5 M Sodium Phosphate, pH 7.5), 1 µl PNGase F, and H2O to a total volume of 10 µl.
- Incubate at 37°C for 16-20 hours.
- Analyze by SDS-PAGE.
