Biocytin is a versatile marker used for neuroanatomical studies and biotinidase assays. Biocytin is water soluble and can be easily detected by avidin and streptavidin conjugates. Also known as vitamin B7 or biotin, is a biologically active form of this essential nutrient. It serves as a cofactor for various carboxylases responsible for metabolizing fatty acids and amino acids. While it occurs naturally in food sources, it can also be synthesized in laboratory applications. Biocytin exhibits a diverse array of biological activities, including antioxidant, anti-inflammatory, and antineoplastic properties. Furthermore, extensive research has been conducted on biocytin to explore its potential in modulating gene expression and cell signaling pathways, highlighting its significance in the field of molecular biology.
