2-[(+)-Biotinamido]ethylamine, often known as biotinylated ethylenediamine or biotin-EDA, is a compound where a biotin molecule is conjugated to an ethylamine group. This compound is used in bioconjugation reactions, where the biotin moiety allows for specific binding to streptavidin or avidin, proteins that have an extraordinarily high affinity for biotin. Such biotin-streptavidin interactions are utilized in various biochemical assays, including immunoassays, protein purification, and cell labeling.
