Sertoli Cell Preparation for Co-immunoprecipitation.

Most techniques to study protein-protein interactions, gene expression or signal transduction, among others, in Sertoli cells, depend on obtaining a protein extract of such cells. This is accomplished by lysing the Sertoli cells and solubilizing the intracellular proteins. Depending on the purpose of your study, the technique used to lyse and consequently obtain protein extracts from Sertoli cells must be considered. In this chapter, we will focus on how to obtain a protein Sertoli cell extract suitable for co-immunoprecipitation technique.
