50 µg of total protein from Arabidopsis thaliana inflorescences were extracted with extraction buffer (50 mM Tris pH7.5; 150 mM NaCl; 1 mM EDTA; 10 % v/v Glycerin; 1 mM DTT, 1x Complete Protease Inhibitor Cocktail, Roche) and denatured with Laemmli buffer at 95ºC 5 min. were separated on 10% SDS-PAGE and blotted 1.5 h to PVDF using tank transfer. Blots were blocked with blocking buffer (3% milk powder; 1x TBS; 0.1% Tween-20) 1 h at RT with agitation. Blot was incubated in the primary antibody at a dilution of 1:10 000 ON at 4ºC with agitation. The antibody solution was decanted and the blot was rinsed briefly and then washed tree times for 15 min. in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera AS09 602) diluted to 1:20 000 in blocking buffer for 1h at RT with agitation. The blot was washed as above and developed for 5 min with chemiluminescent detection reagent of extreme femtogram sensitivity, exposed to Amersham Hyperfilms ECL for 5 minutes. ago10-2 mutant is described here.

AGO expression may be cell/tissue specific and using floral tissue is recommended where most of the AGOs are expressed the highest. Seedlings can be used as a negative control.
Use of proteasome inhibitors as MG132 can help to stabilize AGO proteins during extraction procedure.
AGO10 is involved in miRNA binding, and in RNA-mediated posttranscriptional gene silencing (PTGS).
