Enzymatic DeGlycoMx Kit
This kit developed for protein deglycosylation includes our DeGlycoMx, a premixed cocktail of the enzymes required to remove all N-linked oligosaccharides and most O-linked sugars from 0.5 mg of glycoprotein, via 10 reactions of up to 50 micrograms of protein per reaction.
The kit is easy-to-use and effective: add 2 µl of the DeGlycoMx enzyme to your denatured sample and the included buffer and incubate for 3 hours at 37˚C.
KE-DGMX – 20 microliters
KE-DGMX-100 – 100 microliters
$340.00 – $1,540.00
The enzymes are premixed in either one 20 or 100 microliter vial. This allows researchers to quickly remove most all glycans (with the exception of O-Linked mucins) from their glycoprotein in both denatured and native conditions. By combining the enzymes into one easy-to-use premixed solution, researchers save time and money in the pursuit of protein deglycosylation. The enzymes can also be supplied individually in 20 microliter vials of each enzyme (KE-DG01) allowing the researcher to the flexibility to characterize the glycans attached to their glycoprotein more fully than with our mixture of enzymes.
Other Supplied Reagents:
2. Add 2.5 µl denaturation solution. Mix gently and place in boiling water bath for 5 minutes. Chill on ice.
3. Add 2.5 µl of Triton-X.
4. Add 2 µls of the DeGlycoMx enzyme cocktail. Incubate for 3 hours at 37˚C.
Note: Denaturation increases the rate of enzyme digestion up to 10 fold. If denaturation is not desired omit step 2-3, add with 5 µl of distilled water and increase incubation time up to 24 hours.
