Robotic high-throughput assay for isolating apoptosis-inducing genes

Area of Science:

• Genomics
• Molecular Biology
• Mammalian Cell Biology

Background:

• Increasing genomic data necessitates efficient methods for gene function assignment.
• Systematic functional analysis of genes is crucial for understanding biological processes.

Purpose of the Study:

• To present a novel genetic screen for systematic functional gene analysis in mammalian cells.
• To demonstrate the screen's utility in identifying apoptosis-inducing genes.

Main Methods:

• High-throughput, transient transfections of individual complementary DNAs (cDNAs) using a robotic system.
• A robotic system featuring a moveable pipetting head and a 96-channel parallel tube-pump array.
• Development of a novel assay for apoptosis induction using co-transfected reporter plasmids.

Main Results:

• The robotic system achieves a processing speed of up to 2,000 transfections per hour.
• The genetic screen successfully identified apoptosis-inducing genes.
• A convenient assay for apoptosis induction was established.

Conclusions:

• The developed genetic screen provides a rapid and efficient method for high-throughput functional gene analysis.
• This system facilitates the discovery of genes involved in cellular processes like apoptosis.
• The approach offers a valuable tool for advancing mammalian cell biology research.
