Application examples

Application example

35 µg of total leaf protein extracted with PEB (AS08 300) from wt Arabidopsis thaliana (1) and Arabidopsis thaliana transformed with 35S::FT (2) were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 80 min (30V) to PVDF. Filter was blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-FT/TFT (AS06 198, 1:1000, 1h) and secondary anti-rabbit (1:20 000, 1h) antibody (HRP conjugated) in TBS-T containing 2% low fat milk powder. Antibody incubations were followed by washings in TBS-T (15, +5, +5, +5 min). All steps were performed at RT with agitation. Signal was detected with chemiluminescent detection reagent, using a Fuji LAS-3000 CCD (300s, high sensitivity). Please note that this antibody will not detect FT at 35 µg protein loading in the wt leaf material tested.

Additional information

Note that detection for this product is limited by target threshold level.

Background

In angioperms the 20 kDa protein FT (coded by the gene flowering locus T) promotes flowering under long-day conditions. It has been shown to contribute to flowering initiation upon its expression in leafs followed by transport to apical meristems.
