product information
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.

Application example

Western blot using anti-PTOX antibodies
15 µg from total protein leaf extract of Spinacia oleracea (1), Arabidopsis thliana (2), Solanum lycopersicum (3), Nicotiana tabacum (4), Hordeum vulgare (5), Arabidopsis thaliana thylakoid fraction (6) were separated on SDS-PAGE and blotted to PVDF membrane. Incubation with primary antibody: 1: 4000 followed by chemiluminescent detection. Exposure time 2 minutes.

Cross reactivity to 52 kDa band can be eliminated by using thylakoid fraction or blocking with 10 % milk ON/4°C.
