Application example


Western blot using anti-HSP16.9 antibodies on wheat

24 µg of Triticum aestivum L. whole leaf extract (1), 23 µg of Triticum aestivum L. whole leaf extract 37°С,3h (2), 22 µg of Triticum aestivum L. whole leaf extract, 37°С, 24h (3), 20 µg of Triticum aestivum L. whole leaf extract, 37°С,24h+50°C/1h (4), 17 µg of Triticum aestivum L. whole leaf extract, 37°С,24h+50°C, 3h (5), 23 µg of Triticum aestivum L. whole leaf extract, Control+50°C, 1h (6).

700 µg of total protein from spring wheat Triticum aestivum L. green leaves extracted with write exact buffer components 100 mM Tris HCl (pH=7.4), 1 mM beta-mercaptoethanol, 1 mM PMSF and denatured with 65.2 mM Tris HCl (pH=6.8), 1mM EDTA, 1% SDS, 20% glycerol, 5% beta-mercaptoethanol at 97°C for 5 min and 20 μg of total protein were separated on 12.5 % SDS-PAGE and blotted 2h on nitrocellulose membrane (GE Healthcare) using tank transfer. Blots were blocked with a skimmed milk 3 % in TBS for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 1h at RT with agitation in TBS. The antibody solution was decanted and the blot washed 2 times for 10 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG, ALP conjugated, AS09 607, from Agrisera) diluted to 1:1000 in a skimmed milk 3 % in TBS for 1h at RT with agitation. The blot was washed 3 times for 5 min in TBS-T at RT with agitation and developed WB. The proteins were detected with 5-bromo-4-chloro-3-indolyl phosphate (Thermo Scientific) and Nitrotetrazolium Blue (Thermo Scientific). Exposure time was 5.20 minutes.

western blot using anti-HSP16B antibodies


From 0.1-200 ng of recombinant HSP16B protein from Triticum aestivum were separated on 15 % SDS-PAGE and blotted 1h to nitrocellulose using semi-dry transfer at 15 V for 1 hour in a buffer containing: 48mM Tris, 39 mM Glycine, 0.02% SDS, 20 % methanol, pH 9.2. Blots were blocked with with 2.5% milk in TBS (50mM Tris, 150 mM NaCl, pH 7.5) for 1 hour at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 10 000 for 2h at RT TBS with 2.5% milk with agitation. Three washes (15 minutes each) were carried out with TBS and 0.05% Tween20 at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, diluted to 1:10 000 in  for 1h at RT with agitation. The blot was washed as above and developed using Pierce western blotting substrate (#32106). The exposure time used for visualization was 6.5 minutes.
