Figure 3. Recombinant cGAS protein synthesizes cGAMP(2′–5′) in the presence of poly(rA):poly(dT) hybrids.

Figure 3

RP-HPLC chromatograms showing the presence of cGAMP(2′–5′) after incubation of recombinant cGAS protein for 90 min in the presence of ATP and GTP with different ligands. (i) Synthetic 2′–5′ cGAMP as a positive control, (ii) poly(dA):poly(rU) dsRNA, (iii) poly(rA):poly(dT) hybrid and (iv) poly(dA):poly(dT) dsDNA.
