HA peptide

Basic Description

Synthesis and Functionality ​:
HA Peptide is a 9-amino acid epitope tag (sequence: YPYDVPDYA) derived from the influenza virus hemagglutinin (HA) protein, which is widely used in the detection, purification and localization of recombinant proteins. Its features include:
1. ​​High specificity​ ​：Efficiently binds to Anti-HA antibodies (such as 12CA5, 3F10), suitable for Western Blot, immunofluorescence (IF) and immunoprecipitation (IP).
2. ​​Low immunogenicity​ ​：No cross-reaction in mammalian expression systems, reducing background interference.
3. ​Flexibility ​：Can be fused to the N-terminus, C-terminus or inside of the protein without affecting protein folding and function.

​ ​Application Areas​ ​:
• Recombinant protein purification and detection
• Protein interaction studies (Pull-down, Co-IP)
• Live cell imaging (dynamic tracking of protein localization)
