| Bioactivity | Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first. |
| Description | Influenza A H1N1 (A/New Caledonia/20/1999) Hemagglutinin/HA-specific B cell probe (His) is expressed in Baculovirus insect cells with His tag. The predicted molecular weight is 58 kDa and the accession number is C3W5S1. |
| Species | H1N1 |
| Expression System | Baculovirus Insect Cells |
| Tag | C-His |
| Accession Number | C3W5S1 |
| Construction | A DNA sequence encoding the extracellular domain of Influenza A virus (A/New Caledonia/20/1999 (H1N1)) hemagglutinin (AAP34324.1) (Met1-Val519) with mutations (Y108F, and aa 339-342 SIQS→QRET), was expressed with a polyhistidine tag at the C-terminus. Predicted N terminal: Asp 18 |
| Protein Purity | > 95 % as determined by SDS-PAGE. |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 20 mM Tris, 500 mM NaCl, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization. |
| Reconstitution | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
| Synonyms | Harvey rat sarcoma viral oncogene homolog |
| Research Background | The influenza viral Hemagglutinin (HA) protein is a homotrimer with a receptor binding pocket on the globular head of each monomer.HA has at least 18 different antigens. These subtypes are named H1 through H18.HA has two functions. Firstly, it allows the recognition of target vertebrate cells, accomplished through the binding to these cells' sialic acid-containing receptors. Secondly, once bound it facilitates the entry of the viral genome into the target cells by causing the fusion of the host endosomal membrane with the viral membrane. The influenza virus Hemagglutinin (HA) protein is translated in cells as a single protein, HA, or hemagglutinin precursor protein. For viral activation, hemagglutinin precursor protein (HA) must be cleaved by a trypsin-like serine endoprotease at a specific site, normally coded for by a single basic amino acid (usually arginine) between the HA1 and HA2 domains of the protein. After cleavage, the two disulfide-bonded protein domains produce the mature form of the protein subunits as a prerequisite for the conformational change necessary for fusion and hence viral infectivity. |
| Molecular Weight | 58 kDa (predicted) |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
