ABOUT

Anti-human STING monoclonal antibody for detection

Anti-hSTING-IgG (clone 3B5) is a monoclonal mouse IgG1 antibody against human STING (hSTING). This antibody was generated by InvivoGen using DNA immunization. It has been produced in hybridomas and purified by affinity chromatography.
Anti-hSTING-IgG has been selected for its ability to bind hSTING. It recognizes the most prevalent isoform, “wild‑type” R232 and HAQ hSTING variants. This antibody can be used to detect hSTING using ELISA and Western blot.
STING (stimulator of interferon genes) is essential for the interferon response to cytoplasmic foreign or self-DNA. It directly senses cyclic dinucleotides (CDNs), which are important messengers in bacteria and innate immune agonists in mammals [1]. Several STING variants, which differ in their responses to CDNs, have been described in the human population [2].

Details

STING (stimulator of interferon genes) has become a focal point in immunology research and drug discovery [1, 2]. In a healthy individual, STING functions as a signaling hub, orchestrating immune responses to pathogenic, tumoral, or self-DNA detected in the cytoplasm [2]. Upon activation, STING induces type I interferon (IFN) production through TANK-binding-kinase-I (TBK1)-mediated IFN regulatory factor (IRF3) signaling [2]. STING activation also leads to NF‑κB-dependent inflammatory cytokine production [2]. In some autoimmune diseases such as STING-associated vasculopathy with onset in infancy (SAVI), STING is constitutively activated resulting in high IFN production [3, 4]. The discovery of a mechanism to pharmacologically inhibit STING should lead to new treatments for such diseases.
