Derivatization reagent by acylation

Supplier: Thermo 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.

N-Methyl-N-[tert-butyldimethyl-silyl]trifluoroacetimide (MTBSTFA) and 1% tert-Butyldimethylchlorosilane (TBDMCS) converts Hydroxyl, Carboxyl, Thiol, and Primary and Secondary Amines to TBDMS Derivatives.

Supplier: Thermo Scientific

Use specially manufactured and packaged Thermo Scientific™ Silylation Grade Solvents to meet the exacting needs of silylation and other sensitive derivatization reactions. They are purified, dried, and packaged under nitrogen in convenient Thermo Scientific™ Hypo-Vial™ Sample Storage Vials, and are supplied with elastomer septa to enable immediate access to the sample without exposure to moisture and oxygen. Use polar solvents (acetonitrile, dimethylformamide, dimethylsulfoxide, pyridine, tetrahyrdrofuran) to facilitate reactions; nonpolar organic solvents may be used but will not accelerate the rate of reaction.

Supplier: Thermo Scientific

Ensure consistent, predictable separations of polar and hydrophilic analytes using Thermo Scientific™ Syncronis HILIC columns.
