STING (STimulator of INterferon Genes protein) acts as a sensor of cytosolic DNA from bacteria/viruses or the self (intrinsic) and promotes the production of type I interferons (IFN-alpha and IFN-beta). STING has been suggested to interact with DDX58/RIG-I, MAVS, SSR2, RNF5, TRIM56, TBK1, IFIT1 and IFIT2. It generally localize to the cytoplasm, and membranes of cell, ER and mitochondria but in response to DNA stimulation, it translocate to the perinuclear region for interaction with TBK1 kinase. The latter phosphorylates STING at Ser-358 residue which results in its activation. STING executes its role by spotting and binding cyclic di-GMP / c-di-GMP and cyclic GMP-AMP /cGAMP which follows the activation of NF-kappa B and IRF3 transcriptional signaling pathways leading to the induction of Type I interferon response. STING has also been suggested to involve in cell death signaling pathways through its association with MHC-II and the activation of ERK pathway. Besides immune response to bacterial/viral pathogens, innate immune gene transcription has been of great importance in the elucidation of the causes of auto-inflammatory disease involving the sensing of self-DNA and the generation of effective antitumor adaptive immunity. STING regulated innate signaling has offered critical insights and new opportunities into the development of novel immunization regimes and therapeutics for treatment of infection, autoimmune disorders, inflammation and cancer.

Concentration Calculator

The concentration calculator allows you to quickly calculate the volume, mass or concentration of your vial. Simply enter your mass, volume, or concentration values for your reagent and the calculator will determine the rest.


Molarity Calculator

Calculate the mass, volume, or concentration required for a solution.

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
