Description
Cayman’s cGAS Inhibitor Screening Assay Kit provides a robust and easy-to-use platform for identifying novel inhibitors of human cGAS, which is a cytosolic dsDNA sensor that detects microbial pathogens. The assay directly measures 2’3’-cGAMP produced by cGAS in the presence of DNA, ATP, and GTP. The cyclic dinucleotide product of that reaction is quantified via ELISA using a 2’3’-cGAMP-specific antiserum. The cGAS inhibitor CU-76 is included as a positive control.The ELISA portion of Cayman’s cGAS Inhibitor Screening Assay Kit is a competitive assay with a range of 4.57-10,000 pM, a midpoint of approximately 300 pM (50% B/B0), and a sensitivity (80% B/B0) of approximately 50 pM
