Application example 
10 µg of total protein from samples such as Arabidopsis thaliana leaf (1) , Hordeum vulgare leaf (2), Zea mays leaf (3) were extracted with Protein Extraction Buffer PEB (AS08 300). Samples were diluted with 1X sample buffer (NuPAGE LDS sample buffer (Invitrogen) supplemented with 50 mM DTT and heat at 70°C for 5 min and keept on ice before loading. Protein samples were separated on 4-12% Bolt Plus gels, LDS-PAGE and blotted for 70 minutes to PVDF using tank transfer. Blots were blocked immediately following transfer in 2% blocking reagent or 5% non-fat milk dissolved in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 5 000 (in blocking reagent) for 1h at room temperature with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, and then washed 1x15 min and 3x5 min with TBS-T at room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, recommended secondary antibody AS09 602, Agrisera) diluted to 1:25 000 in blocking reagent for 1h at room temperature with agitation. The blots were washed as above. The blot was developed for 5 min with chemiluminescent detection reagent, according the manufacturers instructions. Images of the blots were obtained using a CCD imager (VersaDoc MP 4000) and Quantity One software (Bio-Rad). Exposure time was 30 seconds.Container and method: in 6 cm Petri dish, gentle shaking at room temperature (RT) Duration: 40 min

Open PublicationExpression pattern of OsMTP8.1. (A) Quantitative real-time RT–PCR analysis of OsMTP8.1 expression in rice shoots and roots grown in different Mn concentrations. Plants were hydroponically grown for 12 d and then for 6 d in a solution containing varying concentrations of Mn (0.05, 0.5, and 200 µM). Histone H3 was used as an internal control. Expression relative to the shoots in the presence of 0.5 µM Mn is shown. Data represent the mean ±SD (n=3). Different letters indicate a significant difference at P < 0.05 using Tukey’s test. (B) Western blot analysis of OsMTP8.1 in shoots and roots. The tonoplast marker protein V-ATPase was detected using a specific antibody. (C) Western blot analysis of OsMTP8.1 in shoots grown in the presence of varying concentrations of Mn (0.05, 0.5, and 200 µM).

Open PublicationDevelopment of transgenic rice with reduced As accumulation in the grains using tissue?specific expression of OsABCC1, ??ECS and ScYCF1. (a) Analysis of the tissue?specific expression of the OsRCc3 promoter by immunostaining OsRCc3 promoter::GUS transgenic plants (RCc3p::GUS) using a GUS antibody. The internode section denoted by broken lines is magnified in the inset surrounded by yellow solid lines. Bar = 100 ?m. (b) Maps of vectors carrying RCc3p?A (RCc3 pro::OsABCC1?V5), RCc3p?AE (RCc3 pro::OsABCC1?V5, ZmUBI pro::??ECS) or RCc3p?AEY (RCc3 pro::OsABCC1?V5, ZmUBI pro::??ECS, RCc3 pro::ScYCF1). (c) Subcellular localization of OsABCC1?V5 in the roots of RCc3p?AEY plants using a sucrose density gradient analysis. Anti?V5, anti?OsABCC1, anti?V?ATPase (tonoplast marker), anti?H+?ATPase (plasma membrane marker) and Bip (ER marker) were used to assess protein abundance in the different compartments. The signal of OsABCC1?V5 corresponded to the signals of OsABCC1 and V?ATPase. (d) Arsenic accumulation in brown rice harvested from T3 transgenic plants transformed with RCc3p?A, RCc3p?AE, RCc3p?AEY, UBIp?A, UBIp?AE or UBIp?AEY. The As concentration was analysed in brown rice from plants grown in soil with a typical basal level of As. The values are means and standard errors (n = 5 plants). Different letters indicate significantly different means (Tukey's multiple comparison analysis, P ? 0.05).

- Background
-
Background: Plant vacuole V-ATPase is responsible for energization of transport of ions and metabolites, and acts as well 'house-keeping' and as a stress response enzyme. V-ATPase is a multi-subunit enzyme composed of a membrane sector and a cytosolic catalytic sector. It is related to the FoF1 ATP synthase.

Fixation:
Peel the epidermis and immediately transfer to the fixative:
1.PME buffer (50mM PIPES PH 6.9, 5mM EGTA, 2mM MgSO4) with 0.05% Triton X-100, 0.25% DMSO, 1mM PMSF, 200-500 µM MBS. (MBS is not stable in solution, it is thus important to prepare it just before use, add the MBS drop by drop to the solution while stirring, because it may precipitate, MBS is needed only to stain for actin filaments).
2.Incubate 5 minutes.
3.Transfer the peels to 3% PFA (paraformaldehyde) in PME buffer with 0.05% Triton X-100, 0.25% DMSO, 50 µM PMSF.
4.Incubate 1hour.
5.Wash twice for 5 minutes with PBS.Permeabilization:
1.Put the epidermal peels between two microscope glass and freeze in liquid nitrogen for 1-2 minutes.
2.Place the glass between two aluminum blocks cooled to –80oC and punch from above gently.
3.Open the two glass while frozen, and slide the epidermal peels into a solution of PBS + 1% Triton X-100, incubate 1.5 hours.
4.Wash with PBS.Staining:
1.Block over night in PBS with 0.05% Triton X-100 and 1% BSA at 4oC.
2.Incubate 1-1.5 hours in the presence of the first antibody diluted in PBS + 0.05% Triton-X100 and 1% BSA.
3.Wash 3X30 minutes in PBS.
4.Incubate in the presence of the secondary antibody as above.
5.Wash as above.

Praveen Kumar | 2014-05-30I used it detect the microsome fraction from the ARabidopsis Col-0 background. It worked great at 1:20000 dilution.Gerhard Obermeyer | 2009-11-18An excellent antibody against subunit E of the V-ATPase. The antibody recognised only one protein band in Western blots at ca. 30 kDa in a microsomal fraction prepared from Lilium pollen grains. Anti-VHA-E was diluted 1:2,500 and an anti-rabbit IgG AP-conjugated (1:5,000) was used for detection.| 2009-07-21This antibody worked very well in the fern Pteris vittata. I used the recommended dilution of 1:1000 and had no problems.Bronwyn Barkla | 2008-11-17Excellent antibody for tonoplast. Recognizes VHA-E subunit from many different species.Highly recommended.
