For the past decade scientists have extensively used ATS secondary toxin conjugates to make their own targeted toxins for in vitro use.
The ability to combine a primary, cell-surface recognizing, antibody with a secondary antibody attached to saporin, and eliminate cells, is a valuable tool in determining antibody specificity and internalization of the receptor.
This tool is a very cost-effective diagnostic method for screening primary antibodies.
ATS also offers direct conjugation to saporin for further testing, or in vivo use.
