The primary advantage of ProteaseMAX™ Surfactant is that it improves identification of proteins in gel by enhanced protein digestion, increased peptide extraction, and minimized post digestion peptide loss. However, ProteaseMAX™ Surfactant can also facilitate in-solution digestion protocols.
ProteaseMAX™ Surfactant offers two major benefits for digesting proteins in solution. First, ProteasMAX™Surfactant efficiently solubilizes proteins. In addition, ProteaseMAX™ Surfactant does not interfere with Mass Spec analysis when used in the recommended amount. Mouse membrane proteins can be solubilized with ProteaseMAX™ Surfactant at room temperature in less than 1 hour.
The second advantage of ProteaseMAX™ Surfactant for in-solution protein digestion is an enhanced rate of proteolysis. ProteaseMAX™ Surfactant can partially or fully denature proteins in an SDS-like manner, giving the protease easier access to cleavage sites.
