Influenza Hemagglutinin Peptide (trifluoroacetate salt)

Influenza hemagglutinin (HA) peptide is a peptide from the hemagglutinin HA1 chain of influenza virus that corresponds to amino acids 98-106 of the full-length protein. Due to its small size, low potential to interfere in protein folding or activity, and strong immunoreactivity, it is commonly used as an epitope tag on recombinant proteins to facilitate their detection and purification.Formal Name: L-tyrosyl-L-prolyl-L-tyrosyl-L-alpha-aspartyl-L-valyl-L-prolyl-L-alpha-aspartyl-L-tyrosyl-L-alanine, trifluoroacetate salt.
