Description

Perfectly suited for excitation with 630–670-nm light sources
Highly sensitive, high extinction coefficient, and high quantum yield
High photostability
High chemical stability, e.g,. against oxidation
Penetrates passively through cell membranes
The ester group is internally cleaved by esterases to cell-impermeable carboxyl groups
