  • Relevance

    NS1 is one of 7 Dengue Virus non-structural proteins which are thought to be involved in viral replication. NS1 exists as a monomer in its immature form but is rapidly processed in the endoplasmic reticulum to form a stable dimer. A small amount of NS1 remains associated with intracellular organelles where it is thought to be involved in viral replication. The rest of NS1 is found either associated with the plasma membrane or secreted as a soluble hexadimer. NS1 is essential for viral viability but its precise biological function is unknown. Antibodies raised in response to NS1 in viral infection can cross react with cell surface antigens on epithelial cells and platelets and this has been implicated in the development of Dengue Hemorrhagic fever.

      why is the actual band size different from the predicted?

      NS1 exists as a dimer (~80 kDa) in unheated samples but is dissociated into a monomer (~40 kDa) when samples are boiled. Ab41623 recognised both forms of NS1.

    Thank you for your reply. These three antibodies are provided as tissue culture supernatant. This is stated in the purity section of the datasheet. It has some sodium azide added to it, but is not provided in a storage buffer. I am sorry we do not know the concentration of these antibodies. Antibody concentration is usually determined by a protein assay. Because the tissue culture supernatant contains many other proteins, this would not be an accurate method in this case. We can estimate that tissue culture supernatantusually containsapproximately 1 - 3 mg/ml or antibody. I am sorry we are unable to provide more precise information on this occasion. However, I hope it is helpful. If you have any further questions, please do not hesitate to contact us.

    Thank you for your enquiry. Wecan only confirm that ab41490 DN1 antibody will recognize NS1 protein from an MVA NS1 recombinant.I am sorry, we have no data from NS1 expressed in E coli or P pastoris However, if your recombinant proteins (ie NS1 from DENV2 strains 16681 or NGC) are folded properly,these antibodies would most likely work. Hence, these antibodies could be used to monitor proper folding of recombinant proteins. However, I am sorry we would not be able to guarantee this, and you would need to test this out yourself. I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.

    Thank you for contacting Abcam. As ab41623 is a tissue culture supernatant, the concentration has not been determined. The following dilutions have been recommended, for western blot 1/50-1-100 and for ICC/IF, 1/5-1/20. The antibody has not been tested in IP and so the optimal dilution has not been determined but I would recommend starting at the higher end and using a 5ul of antibody per 100ug of tissue/cell lysate. You may find that you would have to increase this concentration but it is a good starting point. Please let me know if there is anything else I can help with.
