Properties

Description

The biotin-PEG3-acid molecule is a unique combination of biotin, a PEG3 chain, and an acid group. Biotin is well-known for its high affinity for streptavidin and avidin, making it an excellent targeting moiety in bioconjugation applications. The PEG3 chain increases the solubility of the molecule and reduces non-specific interactions. The acid group provides a reactive site for further chemical modifications, allowing for the attachment of other molecules or functional groups.
