product information

Indole 3 acetic acid (IAA) is the principal auxin in higher plants. This hormone is produced in  in cells in the apex and young leaves of a plant. Plant cells synthesize IAA from tryptophan. Different effects caused by auxines include: induction of cell elongation and cell division and have a subsequent results for plant growth and development.

application example

immunolocalization of auxin in plant tissue

4 days old Arabidopsis thaliana seedlings were treated with 1µM NPA for 24 hours. Seedlings were fixed for 20 min in 4% EDAC in MTSB, and next 30 minutes in 4 % EDAC+ 2% Formaldehyde. Anti-auxin anti-rabbit primary antibody (Agrisera, catalog number 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.
