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.

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).
