RPPA takes advantage of signal amplification protocols used in clinical diagnostic tests, to measure hundreds of analytes simultaneously on hundreds of biological samples, with elevated sensitivity and starting from as low as 25 micrograms of protein extract((Mueller C, Liotta LA, Espina V.

The type of samples that are suitable for such an analytical platform range from tissue and in vitro cultured cells to biological fluids such as urine, serum, saliva or cerebrospinal fluid.
