  • Relevance

    The Epstein-Barr Virus (EBV), also called Human herpesvirus 4 (HHV-4), is a virus of the herpes family and is one of the most common viruses in humans. EBNA2 is one of the few genes of Epstein-Barr virus which are necessary for immortalization of human primary B lymphocytes. The EBNA2 protein acts as a transcriptional activator of several viral and cellular genes.

Thank you for contacting us. As far as we are aware, ab90543 has never been tested in IHC-P. All tested applications are specified on our datasheets, and these are updated as soon as any new information is brought to our attention. It would be very much appreciated if your customer could find this publication again. Could you please ask your customer if it was the specific Abcam antibody reference ab90543 that was used in the publication or if it was the clone [PE2]? If it is the clone, we won't add this publication to our product datasheet since the purity and, more generally, the production process may be different from our own product ab90543. IHC-Fr and IHC-P cannot be grouped onto the same application. Some antibodies would work in both techniques, some would be suitable for either one or the other. If your customer would like to test the antibody in this untested application, we like to encourage all of our customers to submit an Abreview via the online product datasheet. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Plus, each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as gift certificates. To find out more about our Abreview system, please see the following link: I hope this information is helpful. Please do not hesitate to contact me for any further advice or information in this regard.

Thank you for contacting us. The secondary antibody ab6785 (goat anti-mouse IgG, FITC-conjugated) is a suitable secondary for the three primary antibodies you asked about (ab78113, ab90543, and ab3280), as well as ab6276. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
