Description
Measure peptides or amino acids (Ex 340nm, Em 455nm) with phthalaldehyde, a fluorescent, amine-reactive, HPLC pre- or post-column labeling reagent.
Thermo Scientific™ Fluoraldehyde™ o-Phthaldialdehyde Crystals (OPA)
$598.90
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)
