Sulfo-SHPP（水溶性 Bolton-Hunter 试剂）

Thermo Scientific Pierce Sulfo-SHPP, sulfosuccinimidyl-3 -(4-hydroxypheynyl) propionate, also known as water-soluble Bolton-Hunter Reagent, conjugates tyrosine-like functional groups to primary amines to increase the number of tyrosyl groups that can be iodinated by iodine-125 labeling procedures.

Features of Sulfo-SHPP:

• Iodinate before or after coupling Sulfo-SHPP to the molecule of interest
• Useful for introducing tyrosyl groups on proteins sensitive to small amounts of organic solvent
• Useful for labelling cell surfaces without exposing the cells to membrane permeable solvents
