Acylation derivatisation reagents

Supplier: Restek

Acylation reagents offer the same advantage available from silylation reagents: creating less polar, more volatile derivatives. In comparison to silylating reagents, the acylating reagents can more readily target highly polar multifunctional compounds, such as carbohydrates and amino acids. In addition, acylating reagents offer the distinct advantage of introducing electron-capturing groups, thus enhancing detectability during analysis.

2,3-Diaminonaphthalene

Supplier: Abcam

with NO₂- under acidic conditions to form a detectable fluorescent naphthotriazole. The reaction proceeds at acidic pH at room temperature. Fluorescence is monitored following the addition of NaOH, which raises pH, resulting in lower background and increased sensitivity. Also used as a derivatisation-reagent for the determination of selenium at low detection limits.

NHS-Azide and NHS-phosphine reagents, Pierce™

NHS-Azide and NHS-phosphine reagents, Pierce™

Supplier: Thermo Fisher Scientific

The NHS-Azide and NHS-Phosphine Reagents are amine-reactive compounds for derivatising primary amines of proteins or amine-coated polymer surfaces. Once a protein or surface is azide- or phosphine-labelled, the two components are mixed for effective and stable conjugation. Phosphine groups react with azides via a Staudinger reaction to produce an aza-ylide intermediate that is trapped to form a stable, covalent amide bond. Because phosphines and azides are absent from biological systems, there is minimal background labelling of macromolecules found in cells or lysates.
