Soluble: DMF, DMSO, H₂O (>pH₈)

Absorption: (in nm) 571

Emission: (in nm) 585

Extinction (10³): 54

Molecular Formula: C₁₂H₇NO₃

CAS Number: [635-78-9]

Description:
Red fluorophore standard. Widely used in enzyme assay systems.

Note:
1) Absorption and fluorescence of resorufin are pH dependent. Below the pKa (~6.0), Abs. shifts to ~ 480nm and both E and fluorescence quantum yield are markedly lower. 2) Resorufin is unstable in the presence of thiols such as dithiothreitol (DTT) and 2-mercaptoethanol.
