product information

This antibody specifically cross-reacts against xylose residues bound to the protein N-glycans in beta1,2. 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.


xylose residues bound to the N-glycan in beta 1,2

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum
Format Lyophilized in PBS pH 7.4
Quantity 50 ĩg
Reconstitution For reconstitution add 50 ĩl of sterile water

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 western blot (WB)

Additional information

Beta (1,2) xylose is present exclusively in plant N-glycans so antibodies against this sugar moiety should not cross-react with any mammal glycoprotein.

This antibody do not bind free D-xylose. This antibody does not seem to work in immunolocalization.

application example

Total cell extract from Arabidopsis thaliana wild type (1) and cell extracts from different mutants defective in the complex N-glycan maturation pathway (2-5) (data not published yet).

Primary antibody has been used at 2 µg/10 ml of incubation buffer. Detection has been done using ECL.

western blot using anti-xylose antibodies

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).
