    western blot detection using anti-HSP70 chlroplastic antibodies


    Total protein from Arabidopsis thaliana chloroplasts (20 µg) and ,Arabidopsis thaliana leaf extracts (25 µg) were separated on 10% acrilamide gel and electrophoresis prepared according to Schägger and von Jagov (Anl. Biochem., 1987, 166:368-379). After running the gel, proteins were transferred to nitrocellulose membrane using wet transfer (0.22% CAPS, pH 11). Transfer was checked by Ponceau S staining. Blot was destained by several quick washings in distilled water and 1 washing in 1X TBS (10 mM T pH 7.5, 150 mM NaCl) (10-15 min.).Blot was blocked by 1.5 hour in 5% milk in TBST (1X TBS, 0,1 20) After blocking blot was washed quickly twice in TBST and incubated 2 hours with primary antibody (dilution 1: 2000 TBST (dilution 1:1000). Washing: two quick washings in TBST and 3 x 10 min. washings in TBST. Then blot was incubated 45-60 min. with a secondary anti-rabbit antibodies conjugated to peroxidase (dilution 1:10000) in TBST. Washing: as above. After washing blot was incubated 1-2 min. in ECL solution and exposed to Kodak autoradiography film. Exposure time was 10 seconds.

  • Background
  • Background:

    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.

    This antibody is really good. We used it for WB on Arabidopsis seedling samples with both 1:5000 and 1:10000. Stable and still working after 2 years storage at 4 degree.

    This antibody AS08 348 is really good with its high specificity. I used it for immunoblotting with 1:2000 dilution by the coloring method. With its high specificity, I also have successfully used this antibody for immunoprecipitaion. In my practice, this antibody can reconize plastid Hsp70 well in both Arabidopsis and pea.
