MYC stands as one of the most intensively studied oncogenes in cancer biology, functioning as a master transcriptional regulator that controls cell proliferation, growth, and apoptosis. The phosphorylation status at threonine 58 and serine 62 represents a critical regulatory axis governing MYC protein stability and activity. Sequential phosphorylation at these sites creates a phosphodegron that triggers ubiquitin-mediated degradation, making dual-site phospho-specific detection essential for researchers investigating MYC turnover dynamics, oncogenic signaling cascades, and therapeutic targeting strategies.
This recombinant monoclonal antibody, clone 4E9, offers the reproducibility and consistency that phospho-specific detection demands. Produced using recombinant technology with a defined sequence, it eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The rabbit IgG format, raised against a synthetic phosphopeptide encompassing both T58 and S62 sites, ensures precise recognition of this dual-phosphorylated epitope in human samples.
Validation in western blot applications demonstrates reliable performance in HepG2 hepatocellular carcinoma cells, with detection of the expected 57 kDa band corresponding to phosphorylated MYC. Testing in both EGF-treated and untreated conditions provides researchers with confidence when examining growth factor-induced MYC phosphorylation dynamics. The recommended working dilution range of 1:500 to 1:5000 offers flexibility for optimization across different experimental conditions and detection systems.
For investigators exploring epigenetics, nuclear signaling, or oncogenic transcription factor regulation, this antibody provides a dependable tool for dissecting the post-translational mechanisms that govern MYC function in normal physiology and disease states.
