8- (2- [7- Nitro- 4- benzofurazanyl]aminoethylthio)guanosine- 3', 5'- cyclic monophosphate ( 8-NBD-cGMP ), sodium salt
Fluorescent analogue of cyclic GMP
Cat. No.: N 001
CAS No.: [115993-88-9]
Shipping: ambient
Product Name Price (net) Qty
Cat. No.: N 001-01
Unit: 1 µmol / ~0.6 mg
For other salt forms or metabolites please inquire. Potent membrane-permeant fluorescent activator of both isozymes I α and I β of cGMP-dependent protein kinase. While 8-NBD-cGMP is almost nonfluorescent in aqueous solutions, it fluoresces strongly in hydrophobic environments such as hydrophobic protein binding sites (λexc 475 nm, λem 525 nm). Detailed technical information available. Reference: Salowe et al., Biochemistry, 41, 4385 - 4391 (2002).
