General description
Mouse monoclonal antibody purified from serum-free cell culture supernatant by thiophilic adsorption and size exclusion chromatography. Supplied with a positive control lysate consisting of EGF-treated HepG2 cells. Recognizes the ~55 kDa c-fos protein phosphorylated at Ser374 by MAP kinase.
Recognizes the ~55 kDa c-Fos protein phosphorylated at Ser374. Does not detect the unphosphorylated form.
The early gene product c-Fos is expressed following mitogenic stimulation and functions as a sensor for MAPK signal duration. When MAPK activation is transient, MAPK activity declines before accumulation of the c-Fos protein. When MAPK activation is sustained, c-Fos is phosphorylated by MAPK at Ser374. Phosphorylation stabilizes the Fos protein and primes c-Fos for additional phosphorylation at Thr325.
This PhosphoDetect Anti-Fos (pSer³⁷⁴) Mouse mAb (34E4) is validated for use in ELISA, Immunoblotting for the detection of Fos (pSer³⁷⁴).
Immunogen
Human
a synthetic phosphopeptide corresponding to amino acids surrounding the Ser³⁷⁴ phosphorylation site of human c-Fos
Application
ELISA (0.1 g/ml)
Immunoblotting (0.5 g/ml, chemiluminescence)
Physical form
100 µg antibody lyophilized from 2X PBS, PEG, sucrose and 200 µl lyophilized control lysate from EGF-treated HEPG2 cells.
Preparation Note
Reconstitute antibody with 1 ml water (15 minutes, room temperature). Following reconstitution, aliquot and freeze in liquid nitrogen. Reconstituted antibody can be stored at -80°C for up to 1 year. Aliquots may be stored at 4°C for up to 3 months and should be thawed at 37°C. Reconstitute control lysate with 200 µl H₂O. After complete solubilization of the proteins add 200 µl SDS-PAGE sample buffer and incubate at 90°C for 5 min. Following reconsitution aliquot and freeze (-20°C). Avoid freeze/thaw cycles.
Analysis Note
Positive Control
HepG2 cells treated with EGF

Does not detect the unphosphorylated form of c-fos. For immunoblotting use 20 µl control lysate per lane (minigel) for chemiluminescent detection. Antibody should be titrated for optimal results in individual systems.

The duration of intracellular signaling is thought to be a critical component in effecting specific biological responses. This paradigm is demonstrated by growth factor activation of the extracellular signal-regulated kinase (ERK) signaling cascade in the rat pheochromocytoma cell line (PC12
