Biotin-Choline chloride  

Biotin-Choline Chloride/Choline chloride-Biotin is a biotinylated derivative of choline chloride, a quaternary ammonium salt that plays a key role as a precursor of acetylcholine and phosphatidylcholine. Conjugation with biotin enables the use of streptavidin/avidin systems for detection, enrichment, or targeted delivery of choline-based molecules.
Applications:
Biochemical studies of choline uptake and metabolism.
Affinity assays using streptavidin systems.
Fluorescent or biotin-based detection of choline transport in cells.
Targeted delivery platforms in neuroscience and metabolic research.
