A comprehensive analysis framework for evaluating commercial single-cell RNA sequencing technologies.

Area of Science:

• Molecular Biology
• Genomics
• Biotechnology

Background:

• Single-cell RNA sequencing (scRNA-seq) is crucial for understanding cellular heterogeneity.
• Numerous commercial kits exist, but direct comparisons of their performance are limited.
• Standardized evaluation is needed to guide researchers in selecting appropriate scRNA-seq technologies.

Purpose of the Study:

• To comprehensively evaluate and compare nine prominent commercial scRNA-seq kits.
• To assess analytical performance, protocol duration, and cost-effectiveness.
• To introduce and validate the 'read utilization' metric for kit evaluation.

Main Methods:

• Tested nine scRNA-seq kits from four technology groups using peripheral blood mononuclear cells (PBMCs) from a single donor.
• Evaluated kits based on analytical performance, protocol duration, cost, and the novel read utilization metric.
• Analyzed data from a total of 169,262 cells.

Main Results:

• The 10× Genomics Chromium Fixed RNA Profiling kit showed the best overall performance.
• The Becton Dickinson Rhapsody WTA kit offered a good balance between performance and cost.
• The read utilization metric effectively differentiated kits based on efficiency and impact on sensitivity and cost.

Conclusions:

• The study provides a robust comparison of leading commercial scRNA-seq kits.
• The read utilization metric is a valuable tool for assessing scRNA-seq kit efficiency and cost-effectiveness.
• Findings will aid researchers in selecting optimal scRNA-seq technologies for their studies.
