Multiparameter flow cytometric analysis of human STING expression in human peripheral blood leukocytes. Human blood was treated with BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) followed by permeablization with BD Perm/Wash™ Buffer (Cat. No. 554723). Cells were then stained with BD Horizon™ BV421 Mouse Anti-Human CD20 antibody (Cat. No. 563346) and either Alexa Fluor® 647 IgG1, κ Isotype Control (Cat. No. 565571, Top Panels) or Alexa Fluor®647 Mouse Anti-Human STING antibody (Cat. No. 564836; Bottom Panels). Left Panels - Contour plots showing the correlated expression of STING (or Ig Isotype control staining) versus Side Light Scatter (SSC) were derived from gated events with the forward and side light-scatter characteristics of intact leucocytes. Right Panels - Contour plots showing the correlated expression of STING (or Ig Isotype control staining) versus CD20 were derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD FACSCanto™ II Flow Cytometer System.

Preparation And Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
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 Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).

Antibody Details
T3-680
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.

Format Details
Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
