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

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

Thermo Scientific Pierce Fluoraldehyde Crystals are o-phthalaldehyde (OPA), a highly sensitive fluorescent 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.

Features

• 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)
