p-Ser/Phosphoserine Antibody (4A3): sc-81516

p-Ser Antibody (4A3) is a mouse monoclonal IgM antibody that detects phosphorylated serine in mouse, rat, human, and canine samples through applications such as western blotting (WB) and immunoprecipitation (IP). p-Ser (4A3) antibody is available in a non-conjugated form, specifically designed to target a broad range of serine-phosphorylated proteins found in crude cell extracts, with a preference for positively charged amino acids adjacent to phosphoserine. Phosphorylation of serine residues is a critical post-translational modification that plays a vital role in regulating various cellular functions, including signal transduction, cell cycle progression, and apoptosis. The dynamic nature of serine phosphorylation allows cells to respond rapidly to external stimuli, making phosphoserine essential for maintaining cellular homeostasis and facilitating communication between different signaling pathways. Protein kinases, such as those from the Raf, Rsk, ROCK, PAK, Ak, and PKC families, are responsible for catalyzing this modification, and their activity can significantly influence the structure and function of target proteins. Using p-Ser (4A3) monoclonal antibody, researchers can effectively characterize proteins with phosphorylated serine residues and gain insights into the complex cellular pathways that involve serine phosphorylation, ultimately advancing our understanding of cellular signaling mechanisms.

Monoclonal antibodies for mammalian and non-mammalian protein targets represent essentially all targets covered by polyclonal antibodies. Over 8,300 of our antibodies are offered as ImmunoCruz^® conjugates which eliminates the need for a secondary antibody.
