In-gel digestion complete in only 1 hour.[/caption]Identification of proteins resolved by SDS-PAGE requires a lengthy in-gel digestion and extraction procedure. The publication, Mass Spectrometry Compatible Surfactant for the Optimized In-Gel Protein Digestion, Saveliev, S. et al. (2013) Anal. Chem. 85, 907–14, addressed these obstacles by illustrating the technical benefits of the ProteaseMAX™ mass spectrometry surfactant. A recent webinar reviewed key aspects of that paper that included:
Improved peptide recovery from gels: ProteaseMAX™ improved identification of proteins by enhanced protein digestion, increased peptide extraction and minimized postdigestion peptide loss. This is a major benefit for the in-gel digestion of low abundant proteins and enables the use of minimal sample material.
The webinar also contained information regarding the how the structure of ProteaseMAX™ Surfactant enables it to compatible with mass spec and how it can be used for protein denaturation and solubilization.
