Useful:

• Description: Biotin-PEG4-amine is a popular biotinylation reagent with PEG spacer. It can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. PEG spacer increases aqueous solubility of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules.
