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.
