Biobanking strategy and sample preprocessing for integrative research in monoclonal gammopathies

Area of Science:

• Haemato-oncology
• Molecular Biology
• Cell Biology

Background:

• Monoclonal gammopathies often involve scarce aberrant cells, challenging high-throughput research.
• Current research requires substantial starting material, posing difficulties for patient sample acquisition.
• Standardized protocols are needed for effective sample processing in haemato-oncology.

Purpose of the Study:

• To establish optimal laboratory protocols for sample collection, sorting, and preprocessing of monoclonal gammopathy cells.
• To provide guidelines for nucleic acid isolation and amplification techniques.
• To address challenges associated with limited cell numbers in research.

Main Methods:

• Comparison and optimization of freezing and sorting protocols for plasma cells.
• Evaluation of various nucleic acid isolation kits for DNA and RNA yield.
• Assessment of whole genome amplification techniques for small cell populations.

Main Results:

• Quantification of aberrant cell numbers across different monoclonal gammopathies.
• Determination of nucleic acid yield from various isolation kits using limited cell inputs.
• Demonstration of comparable outputs from parallel isolation kits versus specialized kits.

Conclusions:

• Optimized protocols facilitate comprehensive analysis of limited aberrant cells in monoclonal gammopathies.
• Parallel isolation kits provide outputs comparable to specialized kits.
• Whole genome amplification is a valuable method for obtaining complex data from minimal cell samples.
