Application example 
15 µg of Arabidopsis thaliana leaf extract (1), 10 µg of total protein from: Synechocystis 6803 motile (2), Synechocystis 6803 GT (glucose tolerant strain) (3), Synechococcus elongates 7942 (4), Marker - P ierce™ Prestained Protein MW Marker (kat #26612): Total protein was extracted with following buffer: 10 mM Tris HC l, pH 8.0, 0.5% LDS, 4% glycerol, 0.1 mM EDTA were mixed with sample buffer and denatured for 5 min at 95°C. Samples were separated on 10% S DS -PAGE a nd b lo tted 1 h to nitrocellulose membrane (Amersha m Protran) using tank wet transfer (Bio -Rad) in standard transfer buffer in presence of 20% methanol. Transfer of proteins to the membrane was checked using 0,5% Ponceau S staining before the blocking step. Blots were blocked in buffer (2 % lo w -fat milk in 1xPBS, 0,1% Tween) for 1 h at room temperature (RT) with agitation. Blots were incubated in the primary antibody at a dilution of 1 : 5000 for 1 h at RT with agitation. The antibody solutionwas decanted and the blot was rinsed briefly twice, then washed once f or 15 min and 3 times for 5 min in PBS -T at RT with agitation. Blot was incubated in secondary antibody (goat anti-rabbit IgG, AS09 602, Agrisera ) dilut ed to 1 :30 000 in for 1 h at RT with agitation. The blot was was washed as above and developed for 5 min with Clarity Western ECL Substrate and ChemiDoc detection system (Bio-Rad).

-
Additional information (application): It is not determined which isoform of DnaK is recognized by this antibody in Arabidopsis thaliana. - Background
-
Background: Procaryotic Hsp70 protein family includes DnaK, HscA (Hsc66), HscC (Hsc62). Those proteins are involved in protein folding, cell protection from environmental stress and other functions which are vital for a living cell.
