Description

Application

suitable as fluorescent NO-sensor

Other Notes

Sensitive fluorescent indicator for nitric oxide, NO, based on rhodamine chromophore; LOD in the region of 10 nM; it is more photostable and emits at longer wave-length than the corresponding derivative of fluorescein (DAF, Cat. No. 41524)
