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
