    Target

    • Relevance

      SARS (severe acute respiratory syndrome) is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness, such as the common cold, in humans. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The complete sequence of the SARS virus release the coronavirus contains 25 open reading frames. SARS E2 glycoprotein precursor is a 139kDa glycoprotein. It contains a superantigen between residues 690 through 1050 which has relationship to T-cell Receptor alpha-beta V chain protein.

    Question

    ab39839  SARS E protein peptide    Could it be used with Anti-SARS E2 antibody [4A6C9] (ab31951) and Anti-SARS Nucleoprotein antibody [BDI186] (ab28169) to do sandwich assay? I want one antigen (SARS) and two monoclonal antibodies for the test of sars sandwich assay. Could you give me some suggestions ?Thank you!

    Answer

    Thank you for your enquiry. I am sorry to confirm we do not have any SARS antibodies that are tested in sandwich ELISA (sELISA). SARS E2 antibody [4A6C9] (ab31951) and SARS Nucleoprotein antibody [BDI186] (ab28169) are tested in indirect ELISA only. I can suggest to consider trying one of them in an indirect ELISA method. Sandwich ELISA procedures can be difficult to optimise and tested match pair antibodies should be used. Any tested matched pairs would be noted on the datasheet. This ensures the antibodies are detecting different epitopes on the target protein so they do not interfere with the other antibody binding. Therefore, I am sorry we are unable to guarantee our antibodies in sandwich ELISA unless they have been specifically tested for sandwich ELISA. I am sorry we have no suitably tested antibodies for sELISA on this occasion. I can suggest having a look on the Biocompare website. They have an excellent antibody search facility which includes a lot of suppliers. Regrettably, I am also not able to confirm that the ab28169 is raised against the SARS nucleoprotein, so will not detect the ab39839 E2 protein peptide. However, the ab39839 peptide has been specifically used as the immunogen for ab31951 SARS E2 antibody [4A6C9], so these can be used together in indirect ELISA. I hope this will be helpful. Should you have any further questions, please do not hesitate to contact us. Good luck with your research.
