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.

Arabidopsis thaliana plants were 4 weeks old, grown @ 8 h light with 130-150 µE light @22°C and 16 h dark @18°C.

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.
