application example 
20 µg of total protein from flowers and leaves of transgenic Arabidopsis thaliana lines were analysed (expressing the genomic copy of S6K1 tagged with FLAG epitop under the control of its own promoter) extracted with homogenization buffer were separated on 10% SDS-PAGE and blotted 2h to PVDF. Blots were blocked with 5% milk in TBST for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1:750 for overnight at 4C with agitation. The antibody solution was decanted and the blot was washed three times for 15 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated from Agrisera, AS09 602) diluted to 1:10 000 in 2.5% milk in TBST for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was few minutes.

- Additional Information
-
Additional information: So far in applied conditions and extracts endogenous S6K1/2 protein is detectable as a very weak band Additional information (application): Keeping the samples at 4°C all times is of crucial importance, Laucs buffer was used in example below since this is the one which was used routinely by this test laboratory for the work with kinases, Some unspecific bands can be seen, depending upon western blot protocol which is used, Therefore please consider to use a negative control together with your samples - Background
-
Background: Ribosomal S6 kinase 1/2 (S6K1/2) involved in TOR signaling pathway, in osmotic stress response. Activated by PDK1 and repressed during osmotic stress. Expressed in all tissues, especially during high metabolic activity in growing buds, root tips, leaf margins and germinating seeds. Alternative names: AtPK1/AtPK6 S6K1), AtPK2/AtPK19 (S6K2).
