Thank you for your question. Generally, we only recommend purchasing the “X” form if you are going to be using the antibody primarily for ChIP or Gel Supershift. As you are looking for an antibody that can be used for both Western blot and ChIP, I would recommend purchasing the standard form (sc-1663). If you have any further questions or concerns, please feel free to contact our Technical Service department by calling 800-457-3801 option 2, emailing [email protected]
, or using the Live Chat function on our website.
