Molecular Weight: 213.19

Storage: RT, D, L

[C=Cold D=Desiccated F=Frozen L=Light Sensitive RT=Room Temperature]

Soluble: DMF, DMSO, H2O (>pH8)

Absorption: (in nm) 571

Emission: (in nm) 585

Extinction (103): 54

Molecular Formula: C12H7NO3

CAS Number: [635-78-9]

Unit Price (USD): 20 mg $17.30

Bulk Price/unit (when you buy 5 or more): $13.84

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.
