Auxin immunolocalisation in Arabidopsis roots. Four days old Arabidopsis seedlings were treated with 1 µM 1-N-Naphthylphthalamic acid (NPA) for 24 h to enhance accumulation of auxin in roots. Seedlings were fixed for 20 min in 4 % EDAC in 1× MTSB, and next 30 min in 4 % EDAC+ 2 % Formaldehyde. Anti-indole 3 acetic acid (IAA) rabbit primary antibody (Agrisera, AS06 193) diluted 1:600 plus Goat anti-rabbit IgG (H&L), DyLight^® 549 Conjugate (AS09 633) as secondary antibody diluted in 1:3000 (shown in red color) were used.
