Clone Host Grade Applications
Monoclonal Mouse Affinity Purified E B IP
Phosphorylation and dephosphorylation of cellular proteins are central steps in transducing extracellular signals to the cell nucleus. Phosphorylated epitopes may serve as docking sites for the assembly of protein complexes or may alter the 3-dimensional protein structure thus modulating enzymatic activity or the ability to undergo protein-protein-interactions. Modification of proteins on serine residues is mediated by serine/threonine kinases.
Catalog #P4076-22

Clone TypeMonoclonal
Clone No6D664
FormSupplied as a liquid in PBS, pH 7.2, 0.1% sodium azide, PEG, sucrose.
PurityPurified from serum-free cell culture supernatant by subsequent thiophilic adsorption and size exclusion chromatography.
ImmunogenPhosphoserine containing peptides.
SpecificityRecognizes a broad range of serine-phosphorylated proteins in crude cell extracts. The antibody has a preference for positively charged amino acids directly next to the phosphoserine.
Please note that phosphoserine detection by monoclonal antibodies is always dependent on the surrounding amino acid sequence. Species CrossreactivityHuman, mouse, rat and canine.
