  • Relevance
    Hemagglutinin (HA) is a class I viral fusion protein from Influenza virus. It is a major glycoprotein, comprising over 80% of the envelope proteins present in the virus particle. HA binds to sialic acid-containing receptors on the cell surface, bringing about the attachment of the virus particle to the cell, and 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. The extent of infection into host organism is determined by HA. In natural infection, inactive HA is matured into HA1 and HA2 outside the cell by one or more trypsin-like, arginine-specific endoproteases secreted by the bronchial epithelial cells. The HA protein is a homotrimer of disulfide-linked HA1-HA2. It also plays a major role in the determination of host range restriction and virulence. Genetic variation of hemagglutinin and/or neuraminidase genes results in the emergence of new influenza strains.

Thank you for your enquiry. This antibody ab24779 is an ascites fluid preparation. Therefore, I cannot guarantee this will be free of amines and ammonium ions. It is not recommended for use in conjugation as it is better to use purified antibodies in conjugation experiments. I hope this helps. I'm sorry it is not better news for you. Please get back to me if you have any more questions or require any more advice. With thanks

Thank you for your enquiry. Ab16918 and ab24779 will recognize HA-tag sequence you referenced. Ab19985 was raised to purified HA, and will not necessarily bind to that particular sequence. All shipping and pricing information is available on the online datasheets. I have included a link to each below. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. Avian Influenza A Hemagglutinin antibody (ab21292) can be used for the detection of the Hemagglutinin protein from the H5N1 strain of avian influenza A. Avian Influenza Matrix Protein antibody (ab25918) or Avian Influenza Nucleoprotien antibody (ab22285) can be applied for the detection of the H6N1 strain. I have not been able to find reference to other HN strains. Unfortunately our antibodies are not searchable by the strain that they detect. I recommend searching in google using the keywords "(strain)" together with "Abcam". I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
