Preparation And Storage
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The T3-680 monoclonal antibody specifically recognizes human STING (Stimulator of interferon genes protein) which is also known as Endoplasmic reticulum interferon stimulator (ERIS) and Mediator of IRF3 activation (MITA). STING is encoded by TMEM173 (Transmembrane protein 173). STING is a multi-pass transmembrane adaptor protein which is widely expressed in the endoplasmic reticulum of cells. STING acts as a sensor of cytosolic double-stranded DNA derived from bacteria and viruses and promotes the production of type I interferons, IFN-α and IFN-β. Following activation, STING translocates with TBK1 kinase to perinuclear endosomes. The TBK1 kinase phosphorylates and activates interferon regulatory factors, such as IRF3, and NF-κB, which leads to the induction of type I interferon and other immune response genes that play roles in innate and adaptive immunity.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
