FAQs for Astrin Antibody (NB100-74638). (Showing 1 - 1 of 1 FAQs).

  1. We recently bought Astrin antibody from your company (catalog # NB100-74638, date of purchase 24/01/2012). We did not realize this antibody is not for Western blotting until we received it, and we failed to optimize the antibody detection. Because the other Astrin antibodies are still available from Novus Biologicals, we are thinking to purchase another Astrin antibody. However, in order to ensure the successful use of antibody for our research, we would like to ask which Astrin antibody is guaranteed for Western blotting and possibly for immunofluorescence using human cells ? Also, in the case if the antibody does not work, would you consider the refunding or sending us the alternative antibody?
    • We have 6 antibodies that match your requirements, and they can be viewed on our website by searching for Astrin and narrowing your results using the filters on the left-hand side of the screen. We offer a 100% guarantee for the species and applications listed on the products' datasheets and are happy to provide refunds or replacements in the event that they do not perform as promised!
