a

The analytes are defined not only by the molecule to which they bind but also by their antibody epitopes. For this reason, specific antibodies are listed in the “Analyte” column.

b

The HercepTest, 4B5, and CB11 antibodies all bind to the same HER-2 peptide, on the same microbead.

c

The term All refers to all of the HER-2, ER, and PR analytes together on the same microbead.
