Gly-X™ N-Glycan Rapid Release and Labeling with InstantAB™ Kit (96-ct) [GX96-IAB]

Price:

Description

The Gly-X™ N-Glycan Rapid Release and Labeling with InstantAB™ kit utilizes a novel in-solution enzymatic protein deglycosylation followed by room temperature instant labeling of released N-glycans with InstantAB dye. With deglycosylation and labeling carried out in solution, the method is simple, rapid and suitable for automation. After a simple clean-up step, the InstantAB-labeled glycan samples are ready for analysis by UHPLC, LC-MS, MS/MS and other methods. 

Other benefits include:

    • Room temperature instant labeling
    • 5-minute PNGase F digestion provides unbiased N-glycan release
    • Flexible, high-throughput format: process 1 to 96 samples
    • Optimized cleanup removes excess free dye, protein, and other interfering compounds.

    Contains:

      • GX96-100 Gly-X Deglycosylation Module
      • GX96-501 Gly-X InstantAB Labeling Module
      • GX96-502 Gly-X InstantAB Clean-up Module

        FAQs

        Q. Do you have a list of masses for adduct ions of labeled N-glycans seen by MS in positive and negative mode?

        A. Yes, we have a downloadable Excel file listing masses of adduct ions of unlabeled and labeled glycans. The positive mode tab shows glycans labeled by 2-AB, InstantAB, 2-AA, Procainamide and InstantPC. The negative mode tab shows glycans labeled by 2-AB, InstantAB, 2-AA, Procainamide and APTS.

        Q. Can I use more than the recommended upper limit of 40 µg protein per reaction?

        A. Maybe, although it will depend on the protein. You would have to test to ensure that labeled glycans from > 40 µg of your protein can be successfully loaded onto the Gly-X Cleanup Matrix without blockage. 

        Q. My samples are not loading completely onto the Gly-X Cleanup Matrix. What is happening?

        A. This may be caused by the nature of your protein sample, or by matrix effects caused by the composition of your formulation buffer. This can be addressed by using less protein per reaction, or by buffer exchanging your protein prior to starting the Gly-X protocol.

        Q: Can I use Eppendorf microtubes for the Denaturation and Digestion Steps, rather than a PCR plate?

        A: Yes, leave the tubes open for the heating steps, and ensure that material does not get in the lid during mixing.

        Q: Is it possible to use a plate shaker/heater such as the Eppendorf Thermo Mixer C formixing and heating during the Denaturation and Digestion protocols?

        A: Yes, this is possible. Mix rate should be high enough to vortex material in wells.
