Biotin-Thalidomide（Cat No.:I044160）is a bifunctional molecule that combines thalidomide, a ligand for the E3 ubiquitin ligase cereblon (CRBN), with a biotin tag for affinity-based detection or purification. This conjugate is commonly used in chemical biology and PROTAC (proteolysis targeting chimera) research to study protein degradation mechanisms. The biotin moiety enables capture with streptavidin-based tools, facilitating target engagement assays and proteomic profiling. Biotin-Thalidomide is valuable for identifying CRBN-binding partners, validating PROTAC activity, and dissecting the molecular basis of cereblon-mediated ubiquitination pathways in drug discovery and mechanistic studies.
