Application example 
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.

-
Additional information (application): 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. - Background
-
Background: AGO10 is involved in miRNA binding, and in RNA-mediated posttranscriptional gene silencing (PTGS).

TCA/Acetone protein precipitation method for plant proteins
- Grind plant tissue in a liquid nitrogen.
- Continue grinding with 10% TCA solution in acetone (ice cold).
- Precipitate overnight in -20C.
- Spin at 4°C for 1min, 17k rpm > wash with ice cold acetone until you obtain a white pellet.
- Dissolve the pellet in buffer of choice (for example 8M urea containing 5mM DTT, or denaturate in SDS protein loading buffer for 10 min. at 70°C)
- Clarify supernatant
- Measure protein concentration.
- Proceed with a western blot.
Example of a western blot result obtained with this method, which allows high protein load per well, can be found below.
360 µg/well of Arabidopsis thaliana protein extracted by TCA-acetone precipitation from floral tissue and saturated in 8M urea were separated on 15% SDS-PAGE and blotted for 1hour to 0.2 µm nitrocellulose at 100V using wet transfer system. Blots were blocked with 0.5% cold fish gelatin for 1hr at room temp with agitation. Blot was incubated in the primary antibody at a dilution of 1:2500 for an hour at RT with agitation. The blots were washed with 3X 15min TBS-TT at RT with agitation. Blots as incubated in the secondary antibody (DayLight 800) 1:5000 dilution for 30 min. at RT with agitation and washed 1X with TBSTT for 15 min, 1X with TBST for 15min before scanning with the ODyssey IRD scanner.
