Selection Guide for GPR Electroelution Buffers

The GPR®-850 system uses an eight channel microfluidic chip to allow fast electroelutions simultaneously. In order to facilitate better protein extraction for a multitude of protein properties, multiple different buffer formulation have been developed. Each of these buffers contains a Progenta™ Anionic Acid Labile Surfactant (AALS), which provides a safe alternative to SDS-based electroelution buffers. These surfactants are fully compatible with mass spectrometry due to their ability to degrade under acidic conditions. Each buffer has been made for the optimum electroelution of proteins with varying hydrophobic properties and isoelectric points.
