DNA Isolation

DNA Isolation

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

DNA Agarose Gel Electrophoresis

DNA Agarose Gel Electrophoresis

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

Southern Blot

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...

Background:

Point-of-care (POC) detection is vital for timely clinical diagnosis and treatment.
Developing rapid, specific, and cost-efficient DNA detection methods is a key challenge in diagnostics.

Purpose of the Study:

To develop a novel method for activating filter paper surfaces for DNA molecule binding.
To create a cost-efficient and rapid DNA detection system suitable for POC applications.

Main Methods:

Utilized polyamidoamine (PAMAM) dendrimer and p-phenylene diisothiocyanate (PDITC) to functionalize filter paper surfaces.
Developed a multi-step process involving amination and isothiocyanate group generation for DNA binding.
Optimized parameters including probe printing, target DNA preparation, and detection methods.

Main Results:

The functionalized filter paper demonstrated efficient binding of DNA molecules.
High signal intensities were achieved due to the porous structure of filter paper and optimized detection parameters.
The method proved suitable for specific and sensitive DNA detection.

Conclusions:

A novel, cost-efficient method for DNA detection on filter paper has been established.
This method is suitable for POC applications, particularly for infectious disease diagnosis and antimicrobial resistance gene identification.
The developed system offers a promising tool for rapid and accessible diagnostic testing.
