Background

This antibody specifically cross-reacts against fucose residues bound to the protein N-glycans in alpha 1,3. This residue is characterisitc of the plant protein N-glycans and is absent in protein N-glycans from animals. This residue is added in the Golgi apparatus.

Immunogen

core fucose residues bound to the N-glycan in alpha 1,3

Host Rabbit
Clonality Polyclonal
Clone
Purity Affinity purified serum in PBS, pH 7.4
Format Lyophilized in PBS pH 7.4
Quantity 50 µg
Reconstitution For reconstitution add 50 µl of sterile water.
Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
Tested applications ELISA (ELISA), Immunolocalization (IL), Western blot (WB)

Additional information

Alpha (1,3) fucose is present not only in plants but also in some invertebrates (such as nematodes, bees, etc.) . However, cross-reaction with glycoproteins from these organisms is weaker than the one observed in plants. This sugar residue does not exist in mammals, in their endogenous glycoproteins.

application information
Recommended dilution 0.5 µg/ml (ELISA), 1 : 40 (IL), 1 ug/10 ml (WB)
Expected | apparent MW

10 - 100 for various glycoproteins

Confirmed reactivity Higher plants
Predicted reactivity Higher plants
Not reactive in No confirmed exceptions from predicted reactivity are currently known.
Additional information

Controls:

PLA2 (phospholipase 2 from bee venom) which contains only α1.3 fucose, Sigma, product number P9279.

Type II - horseradish peroxidase which contains β1.2 Xylose and α1.3 fucose, Sigma, product number P8250.

The antibody does not recognize alpha 1,6-fucose.

Application examples


western blot using anti-fucose antibodies

The Anti-fucose antibodies exhibit a positive response with PLA2 and Avidin and a negative one with asialofetuin. This suggests this antibody recognizes only α1,3 fucose epitopes.

For each sample, 1µg of purified protein was denatured with leammli sample buffer at 100°C for 10 minutes loaded on a Bis-Tris gel 4-12% and blotted 1h15 to nitrocellulose membrane using semi-dry transfer. Blots were saturated in TBST over night with agitation. Blot was incubated for 2 hours with primary antibody at a dilution of 1:5000 in TBST at RT with agitation. The antibody solution was discarded and after quick whashes with TBST, the blot was washed 3X15 min in TBST. Blot was incubated in secondary antibody (Goat anti Rabbit IgG, HRP conjugated AS09 602 lot 1707 from AGRISERA) diluted to 1:50 000 in TBST for 1 hour at RT with agitation. The blot was washed as above, plus 1 wash in TBS for 10 min at RT with agitation. The blot was developed for 5 min with the kit ECL West Pico Plus from Thermofisher. Exposure time was 5 seconds.

RiboB: RiboNuclease B contains only oligomannosidic N-Glycans. Used here as a negative control. PLA2: Phospholipase A2 from honey bee venom (Apis mellifera) contains α1,3 Fucose residues. aFet: Asialofetuin is a glycoprotein with α1,6 fucose. Used here as a negative control. Av: recombinant Avidin expressed in corn contains α1,3 Fucose residues.

western blot detection using anti-fucose antibodies

Total cell extract from Arabidopsis thaliana wild type (1) and cell extracts from different mutants defective in fucosyltransferases (2-5) (data not published yet).

Primary antibody has been used at 10 µg/10 ml of incubation buffer. Detection has been done using enchanced chemiluminescence (ECL).

Application example 2

Dot blot reaction of anti-Fucose and anti-Xylose antibodies with various controls: Avidin (Fuc+/Xyl+), Fetuin (Fuc-/Xyl-), PLA2 (Fuc+/Xyl-) and Mur1-2 (Fuc-/Xyl+). 2 µl of each extract were spotted on a nitrocellulose membrane, placed on top of 2 WHATMAN filters (one soaked in TBS-T) and dried for 1.5 h at RT. The mem-brane was blocked for 30 min with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and incubated with anti-Fucose(1) (AS07 268, 1:1000) or anti-Xylose(2) (AS07 267, 1:1000) for 30 min and then with secondary anti-rabbit(1:1000) antibody (ALP conjugated, recommended secondary antibody AS09 607). Membrane was washed with TBS-T 3 x 10 minutes before reaction development using alkaline phosphatase reagent BCIP®/NTB premixed solution (Sigma, Prod. No. B6404).
