CST, 62917S, Phospho-STING (Ser366) Matched Antibody Pair

Matched Antibody Pair for studying STING (Ser366) phosphate in the research area. Product Usage Information Matched Antibody Pairs consist of capture and detection antibodies that bind to non-overlapping epitopes. For specific identification of the capture and detection antibodies in this pair, please refer to the data figure caption. Optimal dilutions/concentrations should be determined by the end user. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. Storage Store at -20ºC. This product will freeze at -20ºC so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles . A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Background Stimulator of interferon genes (STING, TMEM173, MITA) is a transmembrane adaptor protein that is a critical component of the cellular innate immune response to pathogenic cytoplasmic DNA (1,2). STING is a ubiquitously expressed protein found predominantly in the ER (1). The enzyme cGAMP synthase (cGAS) produces the second messenger cyclic-GMP-AMP (cGAMP) in response to cytoplasmic DNA (3,4). cGAMP binds and activates STING (3,4). In addition, detection of cytoplasmic DNA by nucleic acid sensors, including DDX41 or IFI16, results in STING activation (5,6). Following activation, STING translocates with TBK1 to perinuclear endosomes and gets phosphorylated by ULK1 at Ser366 (Ser365 in mouse) (7,8). The TBK1 kinase phosphorylates and activates IRF-3 and NF-κB, which leads to the induction of type I interferon and other immune response genes (1,2,7).
