Arabidopsis thaliana CytC6
Mitochondrial proteins (15 ug) from Arabidopsis thaliana mitochondria was separated on 16% acrilamide gel and electrophoresis prepared according to Schägger and von Jagov (Anl. Biochem., 1987, 166:368-379). After running the gel, proteins were transferred to PVDF membrane using wet transfer (Roti®-Blot 2, Roth). Transfer was checked by Ponceau S staining. Blot was destained by several quick washings in distilled water and 1 washing in 1X TBS (10 mM T pH 7.5, 150 mM NaCl) (10-15 min.).Blot was blocked by 1.5 hour in 5% milk in TBST (1X TBS, 0,1% Tween 20) After blocking blot was washed quickly twice in TBST and incubated 2 hours with primary antibody (dilution 1: 1000) in TBST. Washing: two quick washings in TBST and 3 x 10 min. washings in TBST. Then blot was incubated 45-60 min. with a secondary anti-rabbit antibodies conjugated to peroxidase (Agrisera AB, dilution 1:10 000, AS09 602) in TBST. Washing: as above. After washing blot was incubated 1-2 min. in ECL solution (NOWA Kit, Thermo Scientific). Chemiluminescence was detected by BioSpectrum® Imaging System (UVP). Exposure time was 5 seconds.

The presence of cytochrome c in the cysotol is a marker of PCD (programmed cell death).
Cytochrome c is located in inner mitochondrial membrane. It is a small heme protein which, unlike other cytochromes, is highly soluble. This protein is an essential component of the electron transport chain, where it undergoes oxidation and reduction without binding oxygen.
