Description

Desthiobiotin-PNB ester can be used to label antibodies, facilitating their use in diagnostic assays such as ELISA, where the reversibility of desthiobiotin-streptavidin interaction can be advantageous. Additionally, desthiobiotin’s ability to bind and then be gently eluted from streptavidin or avidin makes it valuable for reversible affinity purification processes. This allows for the isolation and recovery of functional proteins under mild conditions. The PNB ester group specifically reacts with primary amines, enabling targeted modification of lysine residues or N-terminal amines in proteins. This site-specific labeling is crucial for studying protein function, interactions, and localization.
