GPR®-850 Gel Protein Recovery System by Protea Biosciences Group, Inc

Proprietary developments in controlling electrokinetic flow have led to the development of a novel method for coupling high efficiency and robust electroelution with sample recovery decoupled from the electric field.

The GPR-850 instrument delivers 500V per channel for rapid sample extraction, typically within 15 minutes. Each GPRchip contains an array of channels for processing up to 8 samples simultaneously. High voltage electroelution within the 8-plex GPRchip™ permit highly efficient sample recoveries with excellent throughput.


GPR-850 System Features:

• Utilizing the GPRchip allows for efficient extraction of proteins down to 100 ng.
• Proprietary decoupled protein recovery allows for easy and efficient collection of protein and post electroelution clean-up
• Eight-channel parallel processing allows up to 8 gel pieces to processed simultaneously in less than 20 minutes
• High voltage gel extraction (500 V) coupled with real-time current monitoring capability for improved process control
• System and reagents specifically designed for down-stream mass spectrometry
• No extensive clean-up necessary
• Each GPR Electroelution Buffer features Progenta Acid Labile Surfactants technology
• Closed system and dedicated GPRchips eliminates sample carryover and reduces contamination risks
• CE mark for conformity with european directives

Applications:

• Top-down proteomics
• Intact mass measurements
• Protein identification and characterization
• Isoform analysis
