Anti-PHOT1 | Phototropin-1

PHOT1 | phototropin-1 is a blue-light photoreceptor which containst light activated serine-threonine kinase domain. Is required for stomatal opening, chloroplast movements, leaf flattening and phototropism. Undergoes blue-light-dependent autophosphorylation. Alternative names: NPH1, RPT1, JK224, Non-phototropic hypocotyl protein 1, Root phototropism protein 1

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.
