Kit contents scale proportionally with size, except sealing tape.
Example: The V1 kit contains 5X the listed quantities above, but will exclude the sealing tape.

For the “C” and “V” kits, the supplied 96-well strip plate consists of twelve 8-well strips in a support frame. This enables custom plate configurations.

Description

The FastScan™ Phospho-STING (Ser366) ELISA Kit is a sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of STING when phosphorylated at Ser366. To perform the assay, sample is incubated with a capture antibody conjugated with a proprietary tag and a second detection antibody linked to HRP, forming a sandwich with phospho-STING (Ser366) in solution. This entire complex is immobilized to the plate via an anti-tag antibody. The wells are then washed to remove unbound material. TMB is then added. The magnitude of observed signal is proportional to the quantity of phospho-STING (Ser366).

*Antibodies in this kit are custom formulations specific to kit.

Specificity/Sensitivity

The FastScan™ Phospho-STING (Ser366) ELISA Kit detects endogenous levels of STING when phosphorylated at Ser366, as shown in Figure 1. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

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).
