Chemical. CAS: 1205744-09-7. Formula: C25H44N4O8S . C8H19N. MW: 560.7 . 129.2. Synthetic. Functionalized biotin. Biotinylated polyethylene glycol (PEG-Biotin) is an avidine or streptavidin reactive PEG derivative that can be used to modify biomolecues or other surfaces through biotin-streptavidin interaction. Used for addition of biotin-PEG to the N-terminus of resin-bound peptides. Can be introduced using standard coupling methods, such as PyBOP or TBTU and has better solubility in DMF and NMP than comparable non-PEG-containing derivatives, such as biotin-Ahx and biocytin.
