Biotin-PEG2-Amine is widely used in bioconjugation and biochemical research due to its unique properties. The biotin moiety allows for strong binding with avidin or streptavidin, making it valuable in applications such as protein labeling, detection, and purification. The PEG2 spacer enhances solubility and reduces steric hindrance, improving the efficiency of bioconjugation processes. This compound is particularly useful in immunoassays, where it can be used to attach biotinylated antibodies or other biomolecules to solid supports. Additionally, it plays a role in the development of drug delivery systems, where it can be utilized to create targeted therapies by linking biotinylated drugs to avidin-conjugated carriers. Its versatility also extends to molecular imaging, where it aids in the visualization of specific cellular components or processes.
