Anti-Measles nucleoprotein antibody [2D7] (ab9882)

Thank you for your enquiry. The molecular weight of the protein (measles nucleocapsid protein) is 52.5 kDa. The size of the orange marker protein is 70 kDa. Please contact us again if you have additional questions.

Thank you for your enquiry about our Measles nucleoprotein antibodies. A nucleoprotein is defined as any of a group of complexes composed of protein and nucleic acid and found in the nuclei and cytoplasm of all living cells, as in chromatin and ribosomes, and in viruses. A nucleocapsid is a unit of viral structure, consisting of a capsid (protein coat) with the enclosed nucleic acid; some simple viruses are naked nucleocapsids, while in others the nucleocapsids form part of a more complex structure. According to the database Expasy.org (http://www.expasy.org/cgi-bin/get-entries?KW=Viral%20nucleoprotein),a viral nucleocapsid protein is a synonym of a viral nucleoprotein therefore indeed they are the same. I have looked at the datasheets of the four antibodies you are interested in and I would recommend looking in particular at the datasheets of ab9882 and ab9397 as both have been tested in WB and therefore are guaranteed to work in this application. Ab9884 also works in WB but at a lower dilution so you will need to use more antibody. Ab9885 has not been tested in WB, only in ICC so is not guaranteed to work in WB. I hope this information will help you choose a suitable antibody for your experiments, please do not hesitate to contact me again if I can be of further help,
