8-N₃-ε-ATP

8-N3-ε-ATP combines the photosensitive activity of 8-N3-ATP (Cat. No. A 043) and the fluorescent properties of ε-ATP (Cat. No. E 004). It is useful for photoaffinity labelling of ATP binding proteins and subsequent detection of the fluorescent label (λexc 285 nm, λem 412 nm). Alternatively, detection may be achievable by using an ethenoadenosine-specific antibody (1G4, compare: Krebs et al., Anal. Biochem., 314, 108 – 115 (2003)).
