Biotin and derivatives
IBA LifeSciences Biotin powder; 2 g
Biotin is a water-soluble B-complex vitamin, also known as vitamin B7 or vitamin H. It binds to the biotin-binding pockets of streptavidin, Strep-Tactin, and Strep-TactinXT with different affinities. As a result, it allows the efficient elution of Strep-tagII or Twin-Strep-tag fusion proteins from Strep-TactinXT, while maintaining the reusability of the resin. It can be used for preparation of Strep-TactinXT elution buffer, Buffer BXT. In addition, biotin can be used for elution of biotinylated proteins from Strep-Tactin, where it binds irreversibly to the resin. Hence, Strep-Tactin cannot be regenerated in this kind of application.

Medchemexpress LLC Biotin-C5-Azide (DecarboxyBiotin-N3) | 1260586-88-6 | C10H17N5OS | 1 ML
Biotin-C5-Azide (DecarboxyBiotin-N3) is a biotin reagent used to prepare biotinylated conjugates. It functions as a click chemistry reagent, containing an Azide group that allows it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) reactions with alkyne-containing molecules. Additionally, it can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
