You searched for: Protein Linking and Labeling Systems
Protein linking and labeling systems provide a convenient means for attaching fluorescent labels or biotins to antibodies and larger proteins. These kits are ideal for use with multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and FISH. These systems are available with a variety of dye colors, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labeling follows a simple protocol of reaction, separation, and then use.

Amine Reactive Biotinylation Kits, EZ-Link™, Thermo Scientific
Supplier: Thermo Scientific
The amine group is the most common target for modifying protein molecules because it is abundant in the majority of proteins either due to the presence of lysine bearing amino side chain functionality or the N-terminal-amine. Amine-reactive biotinylation reagents can be divided into two groups based on water solubility: NHS-esters and sulfo-NHS-esters.

CF®DI Aminooxy, Biotium
Supplier: Biotium
CF®DI aminooxy dyes react with aldehyde/ketone groups on proteins or other biomolecules to form a stable oxime bond. The CF®DI dyes (CF®488DI, CF®555DI and CF®647DI) are designed to match each other for molecular weight and charge. The molecular weights of the same protein conjugated to different CF®DI dye colors are close to each other and the pl of the labeled proteins remains the same.

Pierce™ NHS-Azide and NHS-Phosphine Reagents, Thermo Scientific
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.

Pierce™ DyLight™ PEGylated Dyes, Antibody Labelling Dyes, Thermo Scientific
Supplier: Thermo Scientific
DyLight™ PEGylated dyes display absorption spectra ranging from 550 nm to 783 nm. These reagents fluoresce over a broad pH range, are more intense than Alexa Fluor® or Cy® dyes in many applications and match the output wavelengths of common fluorescence instrumentation. Additionally, the water solubility of the DyLight™ reagents allows a high dye-to-protein ratio without precipitation during conjugation.
