Anti-ABI1 | Abscisic acid insensitive 1

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.

It is of crucial importance to chose a material in which ABI1 protein is highly expressed like seeds or senescent leaf. This protein could not be detected using this antibody in plants grown under optimal (non stressed) conditions, The antibody detects both, recombinant and endogenous ABI1 proteins.

Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles, Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
