I just want to know that your product Anti-CD9 antibody [EPR2949] (ab92726) whether can be used as marker of urinary exosomes in case of Western bolting or not.
Asked on Jul 16 2013
We have not specifically tested this Anti-CD9 antibody [EPR2949] (ab92726) as a marker of urinary exosomes but I can confirm that it can be used in western blot on mouse, rat, and human samples. Additionally, I have done a Google search and found that CD9 is indeed an exosome marker therefore it can be used as you mentioned. For more details about CD9 please see the publication below.
