V5 Peptide is widely used in biomedical research as an epitope tag for detection and purification of recombinant proteins. Due to its small size and high immunogenicity, it is fused to target proteins to facilitate easy recognition by anti-V5 antibodies in techniques such as Western blotting, ELISA, immunofluorescence, and immunoprecipitation. This allows researchers to track protein expression, localization, and interaction within cells. The V5 tag also supports efficient protein purification using antibody-based affinity chromatography. Its compatibility with various expression systems, including mammalian, bacterial, and insect cells, makes it a versatile tool in molecular and cellular biology studies.
