An inexpensive gel electrophoresis-based polymerase chain reaction method for quantifying mRNA levels

Area of Science:

• Molecular Biology
• Genomics Education

Background:

• Undergraduate institutions increasingly adopt microarray technology for genomics education.
• Validating microarray data is crucial but often hindered by the high cost of real-time polymerase chain reaction (PCR).
• There is a clear need for accessible methods to quantify messenger RNA (mRNA) levels in undergraduate teaching and research labs.

Purpose of the Study:

• To develop an inexpensive and student-friendly gel electrophoresis-based method for quantifying mRNA levels.
• To provide an alternative to expensive real-time PCR for undergraduate laboratories.
• To validate microarray data in an accessible format for student research.

Main Methods:

• Developed a gel electrophoresis-based PCR method for mRNA quantification.
• Compared results with microarray analysis and real-time PCR for three selected genes.
• Utilized undergraduate researchers to model student laboratory experiences.

Main Results:

• The gel electrophoresis-based method demonstrated comparable results to real-time PCR.
• This approach proved to be an inexpensive and convenient alternative for undergraduate settings.
• Successful quantification of mRNA levels was achieved using the developed method.

Conclusions:

• The gel electrophoresis-based PCR method is a viable and cost-effective tool for undergraduate genomics laboratories.
• This method facilitates essential data validation for student microarray experiments.
• It enhances the educational experience by providing access to core genomics methodologies.
