application information

western blot using anti-NRT2.1 antibodies

50 µg of microsomal protein from wild type Arabidopsis thaliana (Col 0) roots at various stages of development (21 and 42 days) and from NRT2.1 deletion mutant (KO-NRT2.1) were solubilized with Laemmli x2 sample buffer and were separated on 12 % SDS-PAGE gel. The proteins were transferred (tank transfer, 100 V, 1h) to a PVDF membrane (Immobilon-P, 0.45 um, Millipore). Blot was blocked for 2h with agitation at room temperature in blocking buffer (SuperBlock, Thermo) containing 0.05 % Tween 20 (Thermo). Blot was then incubated for 2h at RT and with agitation in the fresh blocking buffer containing the primary antibody at a dilution of 1:5 000. The antibody solution was decanted and the blot was washed 3 times for 10 min in PBS-T (0.05 % Tween 20, Thermo) 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 buffer, for 2h at RT with agitation. The blot was washed 1 time for 10 min in PBS-T and 2 times for 10 min in PBS. The blot was then incubated with ECL reagent (Super Signal West Pico,Thermo) for 5 min and the chemioluminescence was recorded on LAS 3000,Fuji. Exposure times were between 5-15 min using standard (lowest) sensitivity.

Additional information

Microsomal fraction is recommended to be used as it will have higher amount of NRT2,1 protein, If a total protein extract is used SDS should be applied from the beginning in extraction buffer as well as protease inhibitor coctail

Secondary antibodies



NRT2.1 is a high affinity nitrate transporter which is up-regulated by nitrate. Functions as a repressor of lateral root initiation independently of nitrate uptake.  Synonymes: Protein ACH1, Protein LATERAL ROOT INITIATION 1, ACH1, ATNRT2.1, ATNRT2:1,, LIN1, NITRATE TRANSPORTER 2, NITRATE TRANSPORTER 2.1, NITRATE TRANSPORTER 2:1, NRT2, NRT2.1, NRT2:1, NRT2;1AT
