Alternative structural projections:


8- [Pharos-575]- adenosine- 3', 5'- cyclic monophosphate ( 8-[φ-575]-cAMP )
Membrane-permeant, fluorescent analogue of cyclic AMP
Cat. No.: P 019
CAS No.: [pending]
Shipping: ambient
Product Name Price (net) Qty
Cat. No.: P 019-001
Unit: 0.1 µmol / ~72 µg

For other salt forms please inquire. Cyclic AMP connected to the relatively small Pharos 575 dye (λexc 577 nm, λem 605-617 nm) by a spacer. The fluorophore can be excited e.g. by a Kr/Ar laser. Due to its high lipophilicity and bright red fluorescence 8-[φ-575]-cAMP is especially suitable for studies with intact cells. Upon binding to PKA a small hypsochromic shift is observed. Detailed technical information available. References: Moll et al., BMC Biochem., 9: 18 (2008); Agarwal et al., Sci. Rep., 6:19577 (2016).
