Biotin PEG

Biopharma PEG offers Biotin PEG with high purity, a class of reagents used for biotinylation. It is used as an affinity label for avidin and streptavidin proteins. Biotin-attached PEG creates an extended spacer arm that allows biotin to enter the protein's binding pocket. The PEG moiety also greatly improves the solubility of the biotin-PEG conjugate.
We can provide a broad range of linear and multi-arm Biotin PEG linkers with various functional groups. All of our PEG linkers are of high purity and can be provided in lab and GMP grades. Mail at for more details.
