Antibody arrays, also known as antibody microarrays, are multiplex assays that simultaneously measure the expression of multiple proteins, for more comprehensive insight than you can obtain with a single-target ELISA or western blot.

In addition, by measuring expression levels of multiple proteins from a single sample in a single study, you can obtain insight quickly and have more confidence in the comparability of your measurements than when you spend extra time, sample, and effort—and introduce additional variability—normalizing and comparing multiple experiments.
