Opis

Opis ogólny

2,3-Naphthalenedicarboxaldehyde, also known as NDA, is a novel fluorescent derivatization agent. The fluorescence max. excitation of NDA is in the range of 424 nm and max. emission is achieved at 484nm.

2,3-Naphthalenedicarboxaldehyde is a fluorescent derivatization agent of primary amines, amino acids, and small peptides. The reaction between the amino compounds and NDA results in highly fluorescent and stable derivative compounds.

Zastosowanie

2,3-Naphthalenedicarboxaldehyde is used as a fluorescent labelling agent for quantification of Histamine in human immunoglobulin preparations. NAD is used as a derivatization agent for glutathione to quantify protein glutathionylation. It is a suitable reagent used for the development of fluorescence-based microtiter plate assay for γ-glutamylcyclotransferase.

Cechy i korzyści

NDA based fluorescent assays have the following benefits over O-Phthalaldehyde (OPA):

• High Reaction rate.
• High Fluorescence quantum yield.
• No uncommon excitation wavelength.
• No side reactions.
