Description
Product Detail

The FLAG tag is a short peptide sequence (DYKDDDDK) engineered for tagging proteins to facilitate their detection and purification. It was first introduced in the late 1980s and has since become one of the most commonly used tags in protein research. The sequence is specifically recognized by anti-FLAG antibodies, allowing researchers to isolate and study proteins in a variety of experimental contexts.
