Biotinylate protein amines with this cleavable, long (37.9A) NHS-ester biotinylation reagent containing a reducible disulfide bond in the pegylated, water-soluble spacer arm.

Brand:  Thermo Scientific™ 21442

Product Code. 11801235

Description

Thermo Scientific™ EZ-Link NHS-SS-PEG⁴-Biotin includes disulfide and polyethylene glycol (PEG) groups in its spacer arm to provide biotinylation that is cleavable and which enhances solubility.

Highlights:

• Extended spacer arm reduces steric hindrance in binding to avidin, streptavidin and Thermo Scientific NeutrAvidin Protein
• PEG spacer maintains water solubility of the modified compound
• Disulfide bond in the spacer arm enables the biotin group to be cleaved from the protein by treatment with reducing agent
• Useful in affinity purification experiments where it is necessary to recover biotin labeled protein from immobilized avidin, streptavidin or NeutrAvidin™ Supports
