Supplier:  Thermo Scientific™ 28665

Catalog No. PI28665

Description

Thermo Scientific™ Pierce Iodination Beads are 3mm diameter polystyrene beads that are coated with an oxidizing reagent, which provides efficient activation of iodine-125 for protein or peptide iodination procedures.

Highlights:

• Derivatized, uniform, nonporous polystyrene beads
• Radioiodide incorporation as high as 99%; labeled protein recovery >90%
• Functions over a broad pH and temperature range
• Fast and easy to use: iodinations complete in 2 to 15 minutes
• Reaction stopped by simply removing beads from reaction mixture with tweezers or pasteur pipet; no reducing agent necessary to terminate reaction

Additional Features:

• Iodinates in the presence of azides, detergents, urea and high salt
• Allows efficient iodination of cell membrane surface proteins
• More gentle method for iodination than soluble chloramine-T because there is no contact between the protein and the immobilized oxidizing agent¹
• Highly reproducible iodinations
• Can be used to quantitatively iodinate histidine at pH 8.22
