HA, Hemagglutinin

Source

Influenza A virus (Missouri/11/2025) HA (H1N1) Protein, His Tag (HA1-V52Ha) is expressed from human 293 cells (HEK293). It contains AA Asp 18 - Ile 530 (Accession # EPI_ISL_20077100, GISAID).

Predicted N-terminus: Asp 18

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 63.0 kDa . The protein migrates as 80-100 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a trimer.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

Supplied as 0.2 μm filtered solution in 0.1 M Sodium citrate, 500 mM NaCl, Glycerol, pH5.5 with trehalose as protectant.

Background Introduction

Neuraminidase (NA) and hemagglutinin (HA) are major membrane glycoproteins found on the surface of influenza virus. Hemagglutinin binds to the sialic acid-containing receptors on the surface of host cells during initial infection and at the end of an infectious cycle. Hemagglutinin also plays a major role in the determination of host range restriction and virulence. As a class I viral fusion protein, hemagglutinin is responsible for penetration of the virus into the cell cytoplasm by mediating the fusion of the membrane of the endocytosed virus particle with the endosomal membrane.
