ABI1 is a key component and repressor of the abscisic acid (ABA) signaling pathway. It regulates numerous ABA responses, such as stomatal closure, osmotic water permeability of the plasma membrane, drought-induced resistance and rhizogenesis, response to glucose, high light stress, seed germination and inhibition of vegetative growth. Expressed in seeds and seedlings. Confined to lateral root caps and columella cells in roots. Induced by low temperature, drought, high salt, ABA and ethylene. Activates/represses SnRK2.6/SRK2E/OST1 in response to ABA-dependent stimuli. Alternative names: ABI1, ABA INSENSITIVE 1, AtABI1, Protein phosphatase 2C 56, AtPP2C56, PP2C56.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles.

Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

It is of crucial importance to chose a material in which ABI1 protein is expressed in detectable amounts, following stress treatment like ozone or drought. This protein is not detectable in plants grown under optimal conditions. This antibody will detect both, recombinant and endogenous ABI1 protein.
