western blot image

1µg of total protein
from Horderum vulgare pre heat shock leaf (1), Horderum vulgare post heat shock (2h 40ºC) (2), Zea mays pre heat shock total protein leaf (3), Zea mays post heat shock (2h 40ºC) (4), total protein leaf extracted with Agrisera Protein Eextraction Buffer (AS08 300) were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF (Milipore). Filters were blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-HSP70 antibody (AS08 371, 1:20 000, 1h) and secondary anti-rabbit (1:20 000, 1 h) antibody (HRP conjugated) in TBS-T containing 2% low fat milk powder. All steps were performed at RT with agitation. Signal was detected with chemiluminescent detection reagent with extreme femtogram range.

Protein from Solanum lycopersicum (1) total cell extract ca. 30 -50 µg, (2) and (3) nuclei pellet , (4) and (5) ca. 7 µg of nuclei fraction, (6) and (7) cytoplasmic pellet, (8) ca. 7 µg of cytoplasm fraction, were separated on 10% SDS-PAGE and blotted 1h to nitrocellulose (Schleicher & Schuell). Filters were blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-HSP70 antibody (AS08 371, 1:5000, 3h RT). The antibody solution was decanted and the blot was rinsed briefly. Washed 3 times for 15 min in TBS-T at room temperature with agitation. Blot was incubated with a secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1: 5:000. The blot was washed as above and developed for 1 min with ECL detection reagent according to the manufacturers instructions.

 western blot using plant anti-HSP70 antibodies

200 fmoles of HSP70 protein standard product number AS08 371S (1), 1 µg of total protein from samples such as Lycopersicum esculentum leaf (2), Nicotiana tabaccum leaf, (3)Zea mays leaf (4), Hordeum vulgare leaf (5), Arabidopsis thaliana leaf (6) were extracted with Agrisera 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: 10 000 (in blocking reagent) for 1h/RT  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 AS10 1489, 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 chemiluminescence detection reagent in extreme femtogram range,  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.

Loss of PfHAD1 is required for FSM resistanceData shown are representative of at least three independent experiments. (a) Immunoblot of the parent strain, FSMR strain AM1, and AM1 Hsp110:PfHAD1-GFP. Full blots are shown in Supplementary Fig. 3. Marker units are kilodaltons (kDa). Top panel was probed with anti-PfHAD1 antisera, and the bottom panel was probed with anti-heat shock protein 70 (hsp70) antisera as a loading control. Expected approximate protein masses: native PfHAD1, 33 kDa; PfHAD1-GFP, 60 kDa; hsp70, 74 kDa. (b) FSM IC50s of the parent strain, FSMR strain AM1, and AM1 Hsp110:PfHAD1-GFP. Displayed are the means ą standard error of the mean (SEM). The parent strain has a FSM IC50 of 1.1 ą 0.2 ?M, while AM1 has an IC50 of 5.5 ą 1.5 ?M. Expression of PfHAD1-GFP in AM1 results in an IC50 of 1.4 ą 0.2 ?M. Data shown are mean is normalized such that 100% growth is defined by that of untreated cells, and 0% growth is defined as the smallest value in each data set.

Loss of HAD2 is necessary for FSM resistance. (A) Successful expression of pTEOE110:HAD2-GFP in strain R2 (had2R157X, PFK9) was confirmed by immunoblotting. Marker units are indicated in kilodaltons (kDa). The top blot was probed with anti-HAD2 antiserum (expected masses: HAD, 33?kDa; HAD2-GFP, 60?kDa). The bottom blot was probed with anti-heat shock protein 70 (Hsp70) antiserum as a loading control. (B) Representative FSM dose response demonstrating that expression of HAD2-GFP in strain R2 (had2R157X PFK9) resulted in restored sensitivity to FSM. Strain R2 had an elevated FSM IC50 compared to the parental (par) strain. When HAD2 expression was restored in strain R2, the resulting strain showed an IC50 near that of the parent strain. Data shown are from a representative clone (clone 1) of the HAD2-rescued strain. Additional clones displayed a similar phenotype (see Fig. S2).

This antibody can be used as a marker of cytoplasmic fraction in tomato (Anfoka et al. 2015).

Applied primary antibody dilution in western blot depends upon sensitivity of detection reagents (pico or femtogram for chemiluminescent detection).

Heat-shock protein 70 (Hsp70) is the major stress-inducible protein in vertebrates and is highly conserved throughout evolution. It plays a role as a molecular chaperone and is important for allowing cells to cope with acute stressor insult, especially those affecting the protein machinery. Heat shock cognate protein 70 (HSC70), is a highly conserved protein and a member of the family of molecular chaperones.
