Product Information

Immunogen The soluble domain 466 (M244 until stop codon, ≈ 64 kDa) was cloned into pET16b and transformed into BLR 21 for 467 expression in Escherichia coli UniProt: Q8VZM7-1, TAIR: At5g02940
Host

Rabbit

Purity Serum
Format Lyophilized
Quantity 50 ĩl
Reconstitution For reconstitution add 50 ĩl, of sterile water
Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
Tested applications Western blot (WB)
Recommended dilution 1 : 1000 (WB)
Expected | apparent MW 100 | 75 kDa

Reactivity

Confirmed reactivity Arabidopsis thaliana
Predicted reactivity Camelina sativa, Capsella rubella, Nicotiana benthamiana, Noccaea caerulescens, Pisum sativum, Raphanus sativus,

Application examples

Application examples Western blot using anti-PEC1 antibodies
Samples:
1 – 2,5 ug of Arabidopsis thaliana mutant pec1-1pec2-1
2 – 2,5 ug of Arabidopsis thaliana mutant pec1-2pec2-2
3 – 2,5 ug of Arabidopsis thaliana whole leaf extract

Arabidopsis thaliana tissue was frozen with liquid nitrogen and ground to a fine powder with mortar and pestle. Protein was extracted by mixing with extraction buffer (200 mM tris pH 8.0, 4% (w/v) sodium dodecyl sulfate) to 0.5 g fresh weight/mL and heating at 80°C for 8 min. 5 µl protein extract were separated on 10 % SDS-PAGE and blotted at 75v for 45min to nitrocellulose (pore size of 20 um), using wet transfer. Blot was blocked with 5% milk for 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1000 ON/4°C in 5% Milk-TBS-T 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  matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in  for 1h/RT with agitation. The blot was washed as above and developed for 1 min with chemiluminescent detection reagent following manufacture's recommendations. Exposure time was 120 seconds.

Background

Background The two Arabidopsis POLLUX-like homologs PEC1 and PEC2 represent plastid envelope membrane cation channels with K + conductivity that are required for the stress triggered Ca 2+ release into the stroma.
