[¹³C₂₀,¹⁵N₁₀]-c[G(2′,5′)pA(3′,5′)p] / [¹³C₂₀,¹⁵N₁₀]-2’3′-cGAMP

[¹³C₂₀,¹⁵N₁₀]-c[G(2′,5′)pA(3′,5′)p] is the stable isotope version of the metazoan cyclic dinucleotide second messenger c[G(2′,5′)pA(3′,5′)p] / 2’3′-cGAMP (Biolog Cat. No. C 161). c[G(2′,5′)pA(3′,5′)p] is produced by the mammalian innate immune DNA sensor cGAMP synthase (cGAS) and potently activates the immune signalling protein STING (stimulator of interferon genes). [¹³C₂₀,¹⁵N₁₀]-c[G(2′,5′)pA(3′,5′)p] is suitable as internal standard in LC-MS applications for c[G(2′,5′)pA(3′,5′)p]. The isotopic purity is 98% for ¹³C and ¹⁵N, respectively.
