  • Western blot

    western blot using plant anti-H1 antibodies

    50 µl of a total protein from Arabidopsis thaliana leafs (wt and single, double and triple H1 mutants as well as overexpressed H1 as a GFP fusion) extracted in a following way: samples were grinded in LN2, suspended in 1xSDS buffer (sample:buffer 1:5), sonicated (10 min., max. power, in ice-cooled sonicating bath (BioRuptor, Diagenode, Belgium) and were separated on 15 % SDS-PAGE and blotted 2h to PVDF(Millipore Westran). Blots were blocked with 5 % non-fat milk TBST for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 5 000 for  over night at 4°C with agitation. The antibody solution was decanted and the blot was rinsed  and washed four times for 10 min in TBS-T at RT with agitation in 2.5 % non-fat milk in YBST. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated,from Agrisera, AS09 602) diluted to 1:10 000 in for 1h at RT with agitation. The blot was washed as above and developed for 5 min with a home made ECL. Exposure time was 5 min.

    immunolocalization in plant tissue using anti-H1 antibodies
    Whole-mount immunostaining on Arabidopsis thaliana ovule primordia stage 2-II. Steps involved: clarification (methanol/xylene), cell wall digestion and permeabilization before application of the primary, then secondary antibody for 12-14 hours at 4°C; fixation: BVO buffer: buffer from (Bauwens and Van Oostveld 1996), 2mM EGTA pH7.5, 10% DMSO, 1% Tween in PBS (containg 1% formaldehyde) for 30 min. rotating/shaking plate RT; blocking: none; counterstaining: propidium iodide and mounted in Prolong Gold (Invitrogen); primary antibody dilution: 1:200 in PBS + 0.2% Tween-20; secondary antibody dilution: 1:200 at 4°C, 24h, goat anti-rabbit IgG Alexa 488 conjugated (Molecular Probes (A11008)). 

    H1 immunostaining in Arabidopsis thaliana ovule primordia stage 2-II is in accordance with H1.1-GFP expression pattern (She et al 2013 et al. 2013).

    Preparation of cytosolic and nuclear protein fractions

    1. Prepare protoplasts from 50 ml Arabidopsis thaliana cell culture according to the protocol of PEG transfection.
    2. Resuspend protoplasts in 10 ml GH buffer and keep the solution on ice for 10 min.
    GH buffer: 100mM glycine
    0.1% Hexylene glycol
    0.37M (4.7% w/v) saccharose
    0.3mM Spermine
    1.0mM Spermidine
    pH 8.3 with Ca(OH)2
    3. To release nuclei add Triton X100 to a final concentration of 0.1%. Pipetting gently up and down several
    times with a plastic pipette might be necessary to lyse cells.
    4. After 5min sediment nuclei by centrifugation at 1000 xg for 15 min at 4°C. Save supernatant as the
    cytoplasmic fraction. Wash the pelleted nuclei two times with GHT (GH+0.1% TX100) then finally
    resuspended in a suitable volume of extraction buffer + protease inhibitors.
