  • Application Examples
  • Western blot using anti-plant actin, mouse recombinant antibodies

    10 µg/well of total protein extracted freshly from Arabidopsis thaliana leaf tissue. All lanes shown are from different Arabidopsis thaliana leaf samples extracted simultaneously. Fresh leaf tissue was ground up directly in 1x Bolt LDS loading buffer (Thermo) and 200mM DTT and denatured at 80°C for 10 min. Samples were separated on 12% SDS-PAGE gel and transferred to nitrocellulose by wet transfer for 1hr at 100V. Blot was blocked with 5 % milk in TBST for 1h/RT with agitation. Blot was incubated with Agrisera Mouse anti-actin monoclonal (AS21 4615) at a dilution of 1:1000, in 5% milk with agitation at 1h RT. The blot was rinsed 3 times for 5 minutes in TBS-T with agitation. Then the membrane was incubated with secondary anti-mouse HRP (Agrisera AS09 627) at 1:10 000 dilution in milk for 1hr at room temp. The blots were washed as above and reaction was visualized using ECL reagent and following manufacture's recommendations. The actin band was visualized after 15 seconds of film exposure.

    Detection of plant actin using recombinant monoclonal antibody
    1 - 10 µl of Arabidopsis thaliana (Col-0) seedling extract
    2 - 10 µl of Nicotiana benthamiana seedlings extract
    3 - 10 µl of Nicotiana tabacum leaves extract
    4 - 10 µl of Eschscholzia californica leaves extract
    5 - 10 µl of Salvia plebeian hairy roots extract

    Total protein was freshly extracted from 50 mg of tissues from species listed above, using 100 µl of 2x SDS sample buffer (0.125M of Tris pH 6.8, 4% SDS, 20% glycerol, 10% 2-mercaptoethanol and 0.2% of bromphenol blue) and denatured with the buffer at 100°C for 3 min. 10 µl of samples were loaded and separated in the 10% SDS-PAGE and blotted for 1h to nitrocellulose (pore size of 0.45 um), using: wet transfer in the cold. Blot was blocked with 3 % milk (PBS-T) for 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 10 000/ON with agitation in 3% milk (PBS-T) at 4°C with agitation. The antibody solution was decanted, then washed for 10 min 2 times in PBS-T at RT with agitation. Blot was incubated in matching secondary antibody (Rabbit anti-mouse IgG (H&L), HRP conjugated AS09 627) diluted to 1: 10 000 for 1h/RT with agitation. The blot was washed as above and developed with a chemiluminescent detection reagent. Exposure time was 2 minutes.
