Biological Activity

Influenza Hemagglutinin (HA) Peptide is a synthetic epitope tag peptide derived from human influenza virus hemagglutinin. It binds anti-HA antibodies with high specificity, facilitating competitive elution of HA-tagged recombinant proteins from anti-HA affinity matrices. This peptide enables efficient immunoaffinity purification, immunodetection, and intracellular tracking of target fusion proteins without altering downstream biochemical signaling pathways or target protein function.[1][2]

Solvent Solubility & Note
DMSO 100 mg/mL (90.73 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
Water 100 mg/mL
Ethanol 100 mg/mL
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
