In reality, most immunohistochemist, microbiologist and old school researchers prefer Immunostaining as a way to view biomolecules and cellular structure. The technique is called "Immunofluorescence", by way of fluorescent staining, and I'll guarantee you that all the information, and research study descrips of Bavituximab's MOA have been viewed this way.. In my opinion, anyway.
I would certainly expect FTM and MicrobeMan to concur..
All the best,
