One-step acquisition of functional biomolecules from tissues

Area of Science:

• Biochemistry
• Molecular Biology
• Biotechnology

Background:

• Direct in vivo determination of functional biomolecular chemistry in tissues is challenging.
• Existing biopsy and solubilization methods lack accuracy, reproducibility, and fail to preserve biomolecule functionality.

Purpose of the Study:

• To develop an improved method for in vivo tissue sampling and molecular profiling.
• To overcome limitations of current biopsy techniques in preserving biomolecular integrity and functionality.

Main Methods:

• Screening a combinatorial library of surfactant formulations to identify synergistic combinations.
• Combining optimized surfactants with ultrasound for rapid tissue solubilization.
• Developing the Surfactant-based Tissue Acquisition for Molecular Profiling (STAMP) method.

Main Results:

• Discovery of novel synergistic surfactant formulations enhancing tissue solubilization and preserving biomolecule bioactivity.
• Successful demonstration of STAMP for profiling proteins, lipids, and DNA in skin and mucosal tissues.
• Validation of STAMP for rapid molecular diagnostics of allergies and infectious diseases.

Conclusions:

• STAMP offers a rapid, one-step solution for in vivo functional tissue chemistry determination.
• The method significantly improves upon traditional biopsy techniques for molecular analysis.
• STAMP has potential applications in point-of-care diagnostics and personalized medicine.
