Comparing RNA extraction methods to face the variations in RNA quality using two human biological matrices

Area of Science:

• Biomedical Science
• Biotechnology
• Molecular Biology

Background:

• Ribonucleic acid (RNA) is vital in biomedicine and biotechnology.
• RNA's susceptibility to degradation necessitates specialized handling and extraction methods for purity and integrity.
• Diverse extraction techniques require comparative studies for optimal researcher and biobank sample traceability.

Purpose of the Study:

• To compare the efficacy of seven different RNA extraction methods.
• To evaluate RNA quality and functionality across various extraction techniques and biological matrices.
• To guide researchers and biobanks in selecting appropriate RNA extraction protocols.

Main Methods:

• Comparison of seven RNA extraction methods: manual (TRIzol™), semi-automated (QIAGEN™, Bio-Rad, Monarch®, Canvax™), and fully automated (QIAcube™, Maxwell®).
• Extraction performed on two biological matrices: human Jurkat T cells and peripheral blood mononuclear cells (PBMC).

Main Results:

• Significant differences observed in RNA quality and functionality based on the extraction method and biological matrix.
• Semi-automated and fully automated methods demonstrated superior performance characteristics.

Conclusions:

• QIAcube™ and semi-automated methods are recommended due to lower variability, good functionality, and cost-effectiveness.
• Method selection is critical for ensuring quality standards and reproducibility in experimental procedures and biobank traceability.
• Findings aid researchers and biobanks in making informed decisions regarding RNA extraction protocols.
