Biotin-PEG11-Amine is widely used in bioconjugation and biochemical research due to its unique properties. The biotin moiety allows for strong and specific binding to avidin or streptavidin, making it valuable in applications like protein labeling, detection, and purification. The PEG (polyethylene glycol) spacer enhances solubility, reduces steric hindrance, and improves stability, which is particularly useful in creating biocompatible conjugates. This compound is often employed in the development of diagnostic assays, such as ELISA, as well as in the study of biomolecular interactions. Additionally, it is utilized in drug delivery systems to enhance the targeting and efficiency of therapeutic agents. Its amine group provides a reactive site for further functionalization, enabling the attachment of various molecules for tailored applications in biotechnology and medicine.
