Common Misconceptions about Antibodies: Exactly the same protocol can be applied to all antibodies. Actually no, this is NOT the case.

  1. Why fractionate?
  2. Is the antibody always to blame?
  3. Save time with your western blots. Have you considered simultaneous detection with two primary antibodies?

How to Cite an Antibody in a Scientific Publication?

As more than half of the antibodies used in research cannot be properly identified, it is absolutely crucial to include information, which will allow antibody identification by researchers who want to repeat your experiments. Some journals provide a guideline for antibody citation, unfortunately most of them do not. This issue is most often completely overlooked. Find out how to cite your antibody here.
