Biotin-PEG Reagents

Biotin-PEG Reagents

PEG spacers eliminate the common issues of aggregation with biotinylated proteins, oligonucleotides, antibodies, and other biological materials. They provide optimal avidin/streptavidin binding as the PEG spacer makes the biotin freely available for streptavidin in the capture/binding step. Biotin-PEG reagents are very water soluble, eliminate non-specific binding and are non-antigenic and nonimmunogenic. They significantly increase the signal to noise ratio in analytical applications.
