Synthetic peptide derived from the region of human c-Fos that contains Threonine 232. The sequence is conserved in mouse and rat.
Our Abpromise guarantee covers the use of ab17933 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Lysates prepared from SKBR3 cells were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 3% Milk-TBST buffer for one hour at room temperature, and incubated with c-Fos [pT232] antibody for two hours at room temperature in a 3% Milk-TBST buffer, following prior incubation with: no peptide (1), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphothreonine-containing peptide (3), or, the phosphopeptide immunogen (4). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal™ method.
The data show that only the peptide corresponding to c-Fos [pT232] blocks the signal, thereby demonstrating the specificity of the antibody. While c-Fos [pT232] is phosphorylated in the basal state of SKBR3, EGF treatment induced an increase in the phosphorylation signal (data not shown).Lysates prepared from SKBR3 cells were resolved b
