Detergent-Free Simultaneous Sample Preparation Method for Proteomics and Metabolomics

Area of Science:

• Biochemistry
• Molecular Biology
• Translational Medicine

Background:

• Multiomics research enhances biological system understanding but faces challenges with sample separation and limited sample amounts.
• Existing omics techniques often require destructive separation methods, hindering comprehensive analysis of scarce or heterogeneous samples.

Purpose of the Study:

• To introduce Simultaneous Trapping (SiTrap), a novel, detergent-free method for single-pot multiomics analysis.
• To overcome limitations of current multiomics approaches, particularly for limited and heterogeneous biological samples.

Main Methods:

• Developed a simple, detergent-free method called Simultaneous Trapping (SiTrap).
• SiTrap allows for direct, simultaneous measurement of the proteome and metabolome from the same sample extract.
• Applied SiTrap in a proof-of-principle study using renal cancer tissue biopsies.

Main Results:

• SiTrap facilitates "single-pot" multiomics processing, preserving sample integrity.
• Demonstrated the effectiveness of SiTrap for analyzing limited and heterogeneous samples, such as tissue biopsies.
• Successfully integrated proteome and metabolome data from renal cancer samples using SiTrap.

Conclusions:

• SiTrap is an effective and simple multiomics tool for simultaneous proteome and metabolome analysis.
• The method is particularly advantageous for precious or heterogeneous samples, including clinical biopsies.
• SiTrap holds significant potential as an indispensable tool for translational medical research.
