Abstract
Proteomics is a powerful approach for systematic identification and quantification of the entire proteome of a biological system (cell, tissue, organ, biological fluid, or organism) at specific time points (http://www.nature.com). Extracting and purifying target proteins from native tissues are essential steps for many aspects of proteomic studies. In this chapter, we will introduce the experimental procedures to obtain soluble proteins from two different tissues: (1) the CCT (cpn-containing TCP-1) complex from bovine testes and (2) the protein phosphatase 2A (PP2A) catalytic subunit (PP2Ac or C) from porcine brains. With these two examples, we would like to provide some general guidelines for researchers on how to extract and purify target proteins from specific tissues and extend these approaches to other proteins of interest.
