Background:

Drug development and gene expression studies require efficient sample processing from 96-well cell cultures.
Current methods for mRNA analysis are often expensive and complex.

Purpose of the Study:

To develop a simple, cost-effective method for streamlined mRNA analysis from 96-well cell cultures.
To validate the new method against existing commercial kits.

Main Methods:

A novel method based on the quantitative polymerase chain reaction (qPCR) 'Cells-to-cDNA' approach was developed.
Cell lysis involved SDS, DTT, and proteinase K, followed by heat inactivation and neutralization.
Gene expression was compared using peripheral blood mononuclear cells and two cell lines (SK-HEP-1, U-87).

Main Results:

The developed method demonstrated a mean reduction in Ct values of 2.4 ± 1.3 compared to the 'Cells-to-cDNA' kit.
A mean reduction of 1.4 ± 0.5 in Ct values was observed compared to a spin column-based RNA purification kit.
The new method exhibited lower variability in gene expression measurements.

Conclusions:

A simplified and economical method for mRNA analysis from 96-well plates was successfully established.
This approach offers a viable alternative to expensive commercial kits for gene expression studies.
The method is suitable for applications such as drug development requiring high-throughput sample processing.
