Making DNA Ladder 100 BP Based on Polymerase Chain Reaction Independently

Introduction

The polymerase chain reaction (PCR) is a groundbreaking technique in molecular biology that has revolutionized the field of disease diagnosis and genetic engineering. To interpret PCR results, an electrophoresis approach is necessary, which utilizes DNA ladder as an indicator of DNA size. Currently, Indonesia relies heavily on commercial DNA ladder imported from abroad, which not only requires high costs but also a long delivery time. Therefore, it is crucial for Indonesia to develop the capability to produce DNA ladder independently.

PCR is a widely used technique in molecular biology that enables the amplification of specific DNA sequences. This technique has numerous applications in various fields, including medicine, biotechnology, and forensic science. The ability to produce DNA ladder independently using PCR techniques would not only reduce dependence on imported products but also increase research capabilities in the field of molecular biology.

Objective

The primary objective of this article is to explain the process of making DNA ladder 100 BP independently using PCR techniques with DNA isolated from human blood. This study aims to demonstrate the feasibility of producing DNA ladder using PCR techniques and to assess its quality compared to commercial DNA ladder.

Method

The manufacturing process begins with DNA isolation from human blood using an isolation kit (GIN-70, Sigma-aldrich). The isolated DNA is then used as a template for PCR amplification. The primary set for sizes 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 bp are designed using primary-blast software. The expected DNA products are then produced through a routine PCR process and are visualized using 2% (W/V) Electrophoresis Gel.

The resulting amplicons are then mixed to form 100 bp DNA ladder. The DNA ladder made independently is then compared to commercial DNA ladder to assess its quality. The quality of the DNA ladder is evaluated based on its purity, concentration, and band intensity.

Results and Discussion

The results of DNA isolation showed that the level of purity obtained reached 1,878, indicating that the quality of DNA isolated is good enough for use in PCR. The routine PCR process has succeeded in producing DNA bands with sizes of 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 bp. The concentration of the ribbon for the size of 100, 500, and 1000 bp each reached 300 NG, while for other sizes, the concentration reached 200 NG.

When each DNA band is mixed, a 100 bp DNA ladder is produced which can be used as a reference in electrophoresis analysis. The quality of the DNA ladder made independently is comparable to commercial DNA ladder, indicating that the technique is feasible and reliable.

Conclusion

Making 100 BP DNA Ladder independently using DNA from human blood has been successfully carried out and shows the quality equivalent to commercial DNA ladder. This is an important step for Indonesia in reducing dependence on imported products and increasing research capabilities in the field of molecular biology. This initiative can not only save costs but also accelerate the research process in various fields, including medicine and biotechnology.

In addition, further development of this technique is expected to increase capacity and innovation in the country. The ability to produce DNA ladder independently using PCR techniques would enable researchers to conduct experiments more efficiently and effectively, leading to breakthroughs in various fields.

Future Directions

The development of DNA ladder independently using PCR techniques has numerous applications in various fields, including medicine, biotechnology, and forensic science. Future studies can focus on optimizing the PCR conditions to improve the quality and yield of the DNA ladder. Additionally, the technique can be adapted to produce DNA ladder with different sizes and concentrations, which would be useful for various applications.

Furthermore, the technique can be used to produce DNA ladder with specific modifications, such as labeling or tagging, which would enable researchers to track the movement of DNA molecules in real-time. The ability to produce DNA ladder independently using PCR techniques would enable researchers to conduct experiments more efficiently and effectively, leading to breakthroughs in various fields.
