DISCONTINUED Anti-PTOX | Plastid terminal oxidase

PTOX (plastid terminal oxidase)is a component of electron transfer chain responsible for desaturation of phytoene, which prevents the generation of reactive oxygen species. It is involved in the differentiation of plastids: chloroplasts, amyloplasts, and etioplasts. PTOX is expressed ubiquitously in plant tissues and is located in the lumen.Synonymes: IM, IM1, immutants, AOX4, alternative oxidase 4, ubiquinol oxidase 4, chloroplastic/chromoplastic

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.
