Stimulation of Cytoplasmic DNA Sensing Pathways In Vitro and In Vivo

Overview

This protocol aims to stimulate cytoplasmic DNA sensing pathways in cells and in vivo by generating long, double-stranded DNA through blunt-end ligation. The resulting DNA is used for transfection into cells or mice to induce an innate immune response.

Key Study Components
