western blot using anti-BIK1 antibodies

Total protein from 7-day old Arabidopsis thaliana seedlings Col-0 (wild-type) and bik1 (null mutant) (Lu et al, 2009) were extracted with 50mM HEPES-KOH buffer containing 250 mM sucrose, 5% glycerol, 50 mM NaPP, 1 mM NaMo, 25 mM NaF, 10mM EDTA, 0.5% PVP, 3mM DTT, 1mM PMSF, 10uM Leupeptin & 10nM Calyculin, and then fractionated by ultracentrifugation at 100,000 x gravity for 30 min at 4°C into soluble (S100) and microsomal (P100) proteins as described in LaMontagne et al. (2016). 30 µg proteins of Total, S100, and P100 fractions were denatured at 65°C for 5 min, separated on a 10 % SDS-PAGE and blotted 1h to nitrocellulose using tank transfer. Blots were blocked with 1x PBS (from Fisher Scientific BP665-1) + 0.1 %Tween 20 (PBS-T) + 5% milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1000 overnight at 4°C with agitation in 1x PBS-T + 5% milk. The antibody solution was decanted, and the blot was rinsed briefly once, then washed three times for 7 min in 1x PBS-T at RT with agitation. Blot was incubated with secondary antibody (Goat anti Rabbit IgG (H&L) –HRP conjugated from Agrisera (AS09 602) diluted to 1:10 000 in 1x PBS-T + 5% milk for 2 hr at RT with agitation. The blot was washed as above and developed for 5 min with Amersham ECL (RPN2106). Exposure time was 6 min.

Western blot using anti-BIK1 antibodies

5 and 10 µg of protein from total plant extract of in vitro grown Arabidopsis thaliana Col0 and bik1 mutant were extracted using basic phenol protocol. 1g were grinded with liquid nitrogen with mortair and pestle, powder were resuspended in 3 mL of protein buffer (0.5 M Tris-HCl, 0.7 M sucrose, 1 mM PMSF, 50 mM EDTA, 0.1 M KCl and 0.2% β-mercaptoethanol; pH 8.0). Homogenate were centifuged at 8000 rpm and supernatant were mixed with three volumes of basic phenol, the mixture were incubated with agitation at room temperature during 10 mins. The mixture were centrifuged at 10000 rpm at 4ºC during 30 min, phenolic phase were recuperated in new tube and were mixed with one volume of ammonium acetate 0.1M in methanol, the mixture were incubated at -20 ºC during 4 hours. The mixture were centrifuged at 10000 rpm at 4º C during 20 minutes and protein pellet were washed three times with ammonium acetate 0.1M in methanol. Finally proteins were resuspended in tris-HCl (50 mM, pH 8.0) and the protein concentration were determined according Bradford method. Samples of 5 and 10µg were separated on 15 % SDS-PAGE using tank (BioRad system) to transfer to nitrocellulose membrane during 1 hour at 400 A. Blots were blocked with skimmed milk (10%) for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2 500 for 1h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 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 1:20 000 in 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 20 seconds. For transference control the membrane was stained with Ponceau red and integrity of proteins was evaluated using 12% SDS-PAGE comassie blue stained.

western blot using anti-BIK1 antibodies

Two-week-old seedlings of Arabidopsis thaliana (grown under long day conditions) were infiltrated for 10 mins with flg22 at 1uM or mock, collected and frozen in liquid nitrogen. Approximately 1g of plant material was used for microsomal extraction according to the protocol described by LaMontage et al., 2016). Samples (60ul) were separated on 16 % SDS-PAGE and blotted 2h to PVDF using tank transfer. Blots were blocked with for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 3 000 at 4C ON with agitation in TBS-T + 1% BSA. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602, Agrisera) diluted to 1:20 000 in for 1h at RT with agitation. The blot was washed as above and developed for 2 mins with SuperSignal West Pico Chemiluminescent Substrate. Exposure time was ~ 1 hour.

Antibody is also recognizing phosphorylated form of BIK1. Applied treatment is decreasing pool of non-phosphorylated BIK1 and phosphoryled form is increasing.

Background

Background BIK1 (Botrytis-induced kinase 1) belongs to the protein kinase superfamily. BIK1 is a crucial component of host response signaling required to activate the resistance responses to Botrytis and A. brassicicola infection.
