Phosphorylation is a fundamental post-translational modification regulating essential cellular processes, including signal transduction, cell cycle progression, apoptosis, and differentiation. Aberrant phosphorylation is implicated in cancer, neurodegenerative diseases, and immune disorders, making precise detection of phosphorylation events critical for biomedical research.
OriGene offers more than 900 high-quality antibodies for the detection of phosphoproteins by IHC, WB.
