产品信息

Endo F3 is a highly specific recombinant endoglycosidase which cleaves within the chitobiose core of asparagine-linked fucosylated-biantennary and triantennary complex oligosaccharides from glycoproteins. Endo F3 is tagged with a chitin binding domain (CBD) for easy removal from a reaction and is supplied glycerol free for optimal performance in HPLC and MS intensive methods.

  • 特性和用法

    单位定义

    One unit is defined as the amount of enzyme required to cleave > 95% of the carbohydrate from 10 µg Porcine Fibrinogen in 1 hour at 37°C in a total reaction volume of 10 µl.

    Incubate at 37°C

    GlycoBuffer 4
    50 mM sodium acetate
    (pH 4.5 @ 25°C)

    贮存溶液

    20 mM Tris-HCl
    50 mM NaCl

  • 注意事项

    1. The optimal pH for the cleavage of fucosylated-biantennary (i.e. porcine fibrinogen) and triantennary glycans (i.e. fetuin) is pH 4.5 (10X GlycoBuffer 4). However, fucosylated-biantennary glycans can also be cleaved at pH 6.0 (10X GlycoBuffer 3).
    2. The enzyme should be used under non-denaturing conditions. Detergents, such as SDS, inhibit Endo F3 activity.
    3. Reactions may be scaled-up linearly to accommodate larger reaction volumes.

  • 实验技巧

    • Endo F3 is tagged with a chitin binding domain (CBD) for easy removal from a reaction using chitin magnetic beads (NEB #E8036)
    • Endo F3 should be used under non-denaturing conditions. Detergents, such as SDS, inhibit Endo F3 activity.
    • The optimal pH for the cleavage of triantennary glycans (i.e. fetuin) is pH 4.5 (10X Glycobuffer 4).
    • Fucosylated-biantennary glycans (i.e. porcine fibrinogen) can be cleaved at both pH 4.5 (10X Glycobuffer 4) and at pH 6.0 (10X Glycobuffer 3).
