    The nucleoprotein (NP) of Influenza virus encapsulates the negative strand of the viral RNA and is essential for replicative transcription. It may also be involved in other essential functions throughout the virus life cycle. As well as binding ssRNA, NP is able to self associate to form large oligomeric complexes. NP is able to interact with a variety of other macromolecules of both viral and cellular origins. It binds the PB1 and PB2 subunits of the polymerase and the matrix protein M1. "NP has also been shown to interact with at least four cellular polypeptide families: nuclear import receptors of the importin class, filamentous (F) actin, the nuclear export receptor CRM1 and a DEAD box helicase BAT1/UAP56" (Portela et al 2002).

    Thank you for your response to my further questions. It is very much appreciated.

    When experiments are carried out using transfected cells, it is very important to provide information about the construct and any positive controls used to make sure that the experiments are nicely controlled. Without these details and the exact strains of the virus, it is hard to troubleshoot and to provide sufficient technical support.

    We have not received any similar complaint about ab128193, thus not aware of any QC issues. Currently, we have the same batch in stock your customer has tried. I could offer you a new vial of ab128193 or one vial of any alternative antibodies against the same target protein (Influenza A Virus Nucleoprotein).

    We have the following antibodies which are suitable for Western blot application:

    - https://www.abcam.com/ab43821: Anti-Influenza A Virus Nucleoprotein antibody [9G8]

    - https://www.abcam.com/ab66191: Anti-Influenza A Virus Nucleoprotein antibody [B247M]

    - https://www.abcam.com/ab81126: Anti-Influenza A Virus Nucleoprotein antibody [15]

    Please could you discuss it with your customer and let me know how he/she would like to proceed.

    I look forward to hearing from you soon.

    Thank you for contacting us. The antibodies have different clone number, concentration is different, purity is different, storage buffer percentage is different, and these are tested in different applications. Although these products are against same target but they are different in above mentioned properties. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    ab66191 has been produced using purified Influenza A virus - the immunogen was not a recombinant protein.

    Unfortunately we are not aware of any publications for ab66191. However, ab66191 gave a single band against purified Influenza A antigens (H1N1 and H3N2 strains) on the blot (SDS-PAGE, reducing conditions, 1ug antigen/lane). The antibody was tested at 5ug/ml followed by anti-Mouse IgG HRP conjugate.
