application example 1
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).

Immunolocalization using anti-fucose antibodies on a 40µm vibratome section of a 21 day old Arabidopsis thaliana hypocotyl (wood). Fixation: 4% formaldehyde fixation in 1X PME (100 mM PIPES, 1 mM MgSO4, 2 mM EGTA); blocking: 5 % BSA; primary antibody dilution: 1:40; secondary antibody: 1:300 AlexaFluor568 from Invitrogen (Life Technologies), Alexa Fluor® 568 Goat Anti-Rat IgG (H+L); Left panel, immunolabel channel (cyan) overlaid on grayscale channel (0.001% Calcofluor white which stains cellulose and hemicellulose). Right panel, only immunolabelling
