Thermo Scientific™ Fluoraldehyde™ o-Phthaldialdehyde Crystals (OPA)

Description

• Thermo Scientific™ Pierce Fluoraldehyde (OPA) is o-phthalaldehyde, a highly sensitive fluorescent pre- or post-column derivatization reagent for peptide or amino acid detection and quantitation in HPLC
• Fluoraldehyde Crystals are a specially purified, fluorogenic-grade preparation of o-phthalaldehyde (OPA)
• This amine-reactive compound is primarily used for high-sensitivity, fluorescent detection of primary amines, including amino acids, peptides, proteins and polyamines in pre- or post-column chromatographic effluents
• Highlights: For pre- or post-column amino acid derivatization for fluorescent detection and quantitation Reacts with all primary amine-containing analytes to yield fluorescent derivatives (ex/em = 340nm/455nm) Provides an accurate measure of both composition and absolute protein-peptide content Ideal for work with recombinant proteins and synthetic peptides Can be used for fluorescent protein or peptide assay Can be prepared as a stable aqueous solution in borate (see instructions) Reagent Properties: Can be prepared as a stable aqueous solution in borate (see instructions) Alternative names: Fluoraldehyde Crystals, OPA Chemical name: ortho-Phthalaldehyde Reactive toward: Primary amines (–NH2) Chemical formula: C8H6O2 CAS number: 643-79-8 Molecular weight: 134.12 Form: Pale yellow, free-flowing crystals
