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 sales@biochempeg.com for more details.
