    Western blot using anti-plant GLDP | Glycine decarboxylase P protein antibodies

    6 µg of total protein extracted freshly from Z. mays = Zea mays, A. tha= Arabidopsis thaliana, O. sat = Oryza sativa,  was freshly extracted from  leaf tissue in extraction buffer (50 mM HEPES-KOH pH 7.1, 1 mM EDTA pH 8.0, 10 mM DTT, 5 mM MgCl2, 1 mM PMSF, 20 µg/ml chymostatin, 25 µg/ml aprotinin, 1X Protease Inhibitor Cocktail VI, Plant Cell (AG Scientific)). Proteins were denatured with sample buffer (1X = 62.5 mM Tris-HCl pH 6.8, 2% [v/v] SDS, 10% [v/v] glycerol, 0.01% [w/v] bromophenol blue (Sigma), 100 mM DTT), heated to 95°C in a water bath for 3 minutes and collected at 13523 x g in a bench centrifuge. 6µg of protein was loaded per well and separated on a 12% resolving gel (0.375 M Tris-HCl pH 8.8, 12% [v/v] acrylamide, 0.1% [v/v] ammonium persulfate and 0.05% [v/v] TEMED) and 5% stacking gel (0.125 M Tris-HCl pH 6.8, 5% [v/v] acrylamide, 0.1% [v/v] SDS, 0.1% [v/v] ammonium persulfate and 0.025% [v/v] TEMED). Proteins were blotted onto nitrocellulose membrane (pore size 0.45 µm) using Trans-Blot Semi-Dry Transfer Cell (Bio-Rad), and transfer was run at 25 mA per gel stack for 1½ hours. Blots were blocked in blocking solution (5% [w/v] skim milk powder in TBST (12.5 mM Tris, 137 mM NaCl, 2.7 mM KCl, 0.1% [v/v] Tween-20 detergent)) overnight at room temperature with gentle agitation. The blot was rinsed three times quickly in TBST, then incubated in the primary antibody solution at a dilution of 1:5000 in blocking solution for 1 hour at room temperature with gentle agitation. Blots were rinsed three times quickly in TBST, then washed three times for 5 minutes in TBST at room temperature with gentle agitation. Blots were then incubated in secondary antibody solution (goat anti-rabbit IgG horse radish peroxidase (Sigma) diluted 1:3000 in blocking solution) for 1 hour at room temperature with gentle agitation. The blot was washed three times for 5 minutes in TBST at room temperature with gentle agitation, then rinsed twice in TBS (12.5 mM Tris, 137 mM NaCl, 2.7 mM KCl). Blots were developed with chemiluminescent detection reagent, following manufacture's recommendations, incubating at room temperature for 1 minute and imaged with Bio-Rad ChemiDoc system. Exposure time was 40 seconds.

  • Additional Information
  • Additional information (application): So far only leaf tissue has been used for immunolocalization and western blot experiments
  • Background
  • Background: GLDP (Glycine decarboxylase P protein) catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor. Is involved in response to cadmium ion.
