Description

Perfectly suited for excitation with the 633-nm or 635-nm diode lasers
Highly sensitive; high extinction coefficient and high quantum yield
High photostability
High chemical stability e.g. against oxidation
Penetrates passively through cell-membranes
Ester group is internally cleaved by esterases to cell-impermeable carboxyl groups
