In mammalian proteomes, it is estimated that 6,000–8,000 genes encode for membrane proteins. Yet, large scale proteomic analysis of these same membrane proteins remains a challenge. The hydrophobic nature of membrane proteins most commonly results in poor protein solubility. For in-gel digestion protocols, poor protein solubility for both hydrophobic and hydrophilic peptides results in inefficient digestion and peptide extraction.
