The retinoblastoma protein (pRB) plays a key role in proliferative control and genome stability. For these reasons its functions are considered to be tumor suppressive. Its functional status offers critical insight into proliferative control signaling in tissues and in developing malignancies. In this chapter, we outline basic procedures to detect the retinoblastoma protein in formalin fixed, paraffin embedded tissue sections. In addition, we provide protocols to detect phosphorylation levels of pRB in tissues and offer controls to ensure fidelity of measurement. Importantly, these staining methods utilize broadly available reagents and equipment making them accessible to most biomedical research laboratories.
