The Thermo Scientific EZ-Link NHS-PEG4 Biotinylation Kit contains EZ-Link NHS-PEG4-Biotin and accessory reagents required for 8 1–10 mg protein labeling reactions. EZ-Link NHS-PEG4-Biotin is a pegylated, water-soluble reagent for simple and efficient biotin labeling of antibodies, proteins and other primary amine-containing macromolecules.

Features of EZ-Link NHS-PEG4-Biotin:

Protein labeling—biotinylate antibodies or other proteins for detection or purification using streptavidin probes or resins
Amine-reactive—reacts with primary amines (-NH2), such as the side-chain of lysines (K) or the amino-termini of polypeptides
Pegylated – spacer arm contains a hydrophilic, 4-unit, polyethylene glycol (PEG) group
Enhances solubility – pegylation imparts water solubility to the biotinylated molecule, helping to prevent aggregation of biotinylated antibodies stored in solution
Irreversible—forms permanent amide bonds; spacer arm cannot be cleaved
Long reach – spacer arm (total length added to target) is 29 angstroms; this reduces steric hindrance when binding to avidin molecules

NHS-PEG4-Biotin is a long (29.0Å), pegylated, water-soluble, NHS-ester biotinylation reagent to label amines and maximize solubility of antibodies and other proteins. The N-hydroxysuccinimide ester (NHS) group reacts specifically and efficiently with lysine and N-terminal amino groups to form stable amide bonds. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the biotinylated molecule, thus reducing aggregation of labeled proteins stored in solution. The PEG spacer arm also gives the reagent a long and flexible connection to minimize steric hindrance for binding to avidin molecules.

We manufacture biotin reagents to ensure the highest possible overall product integrity, consistency and performance for the intended research applications.

N-Hydroxysulfosuccinimide (NHS) esters of biotin are the most popular type of biotinylation reagent. NHS-activated biotins react efficiently with primary amino groups (-NH2) in alkaline buffers to form stable amide bonds. Proteins (e.g., antibodies) typically have several primary amines that are available as targets for labeling, including the side chain of lysine (K) residues and the N-terminus of each polypeptide.

Varieties of biotin NHS-ester reagents differ in length, solubility, cell permeability and cleavability. Non-sulfonated NHS-biotins are cell permeable but must be dissolved in organic solvent such as DMSO or DMF. Sulfo-NHS biotins (and those with pegylated spacers) are directly water soluble but not membrane permeable. Varieties containing disulfide bonds can be cleaved using reducing agents, enabling the biotin group to be disconnected from the labeled protein.

常见问题解答 (FAQ)

How do the EZ-Link Micro Biotinylation Kits differ from the standard biotinylation kits?

The standard biotinylation kits contain components for labeling 1-10 mg of protein, and the Micro Biotinylation Kits are structured for labeling 50-200 µg of protein in 200-700 mL. The Micro kits contain the biotinylation reagents in small, individual packages and do not include components to perform the HABA assay.

That osteocalcin (OCN) is necessary for hippocampal-dependent memory and to prevent anxiety-like behaviors raises novel questions. One question is to determine whether OCN is also sufficient to improve these behaviors in wild-type mice, when circulating levels of OCN decline as they do with age. Here we show that the presence ... More
