    western blot detection using anti-patatin antibody

     



    75 µg of total protein from Solanum tuberosum v. Nicola  extracted with 20 mM TRIS PH-8.5, 10 mM thiourea,10mM CaCl2, 5mM DTT, 1 mM PMSF, 1%PVPP  were separated on 4-20 % SDS-PAGE and blotted 1.5h to PVDF. Blots were blocked with 5% milk powder in T-TBS (2.5gr of powder in 50 ml T-TBS)  for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2 000 for overnight at 4°C with agitation. The antibody solution was decanted and the blot was washed 6 times for 5 min. in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602) diluted to 1:10 000 in blocking solution  for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was 30  seconds.

    western blot using anti-patatin antibodies

    Proteins were extracted from tuber flesh of Russet Burbank with 0.1 M Tris HCl (pH=8.0), 5% sucrose (m/v), 2% (m/v) SDS, protease inhibitors (PMSF 1mM). Samples were heated 95°C 5 min, and 1 μg of total protein was resolved in 12% SDS PAGE and blotted to PVDF membrane for 1h-1.5h. Blocking with a 4% skimmed milk in T-TBS (1.5h). Primary antibodies were applied overnight +4°C in dilution 1:2000. After washing with T-TBS 2-3 times, membrane was incubated with secondary antibodies (Goat Anti-Rabbit HRP conjugate) 1:10 000 for 1 hour at RT. The blot was developed with ECL (Clarity Western ECL Substrate, BioRad, 170-5060) for 5 – 10 minutes. Exposure time – 0.4 second.

  • Background
  • Background:

    Patatin is the most abundant protein in potato (Solanum tuberosum L.) tubers, about 60 % of a total protein. It serves as a storage protein. Mature tuber patatin variants are dimers of 40-42 kDa subunits without disulphide bridges.
