HA Tag

Overview

The HA Tag peptide is an important tool for researchers who are working with proteins from the influenza hemagglutinin family. This peptide’s primary role is to facilitate the attachment of the influenza virus to cell receptors, thereby initiating the infection process. While its biological activity is primarily associated with viral functions, the HA tag is widely utilized as a generic epitope tag in expression vectors. Various recombinant proteins can be engineered to express the HA tag without negatively affecting their bioactivity or biodistribution, making it a frequent choice in protein research.

Key Features

• Derived from the influenza hemagglutinin family
• Used as a versatile epitope tag in expression vectors
• Compatible with a range of recombinant proteins
• Does not interfere with protein bioactivity or biodistribution
• Ideal for applications in protein labeling and detection
