Abstract

Candidiasis is a disease caused by the fungus Candida sp.,  which can infect the skin, hair, mucous membranes, and internal organs. Laboratory diagnosis  of Candida albicans can be done molecularly with the aim of identifying fungal DNA through DNA isolation as an initial stage. This study used an experimental research design used to compare two DNA isolation methods, namely filter-based kits and cooling. DNA purity is assessed by measuring absorbance at 260 nm and 280 nm. Qualitative evaluation is carried out through visualization of DNA bands in electrophoresis. After conducting five DNA re-isolation experiments for both filter-based kit and cooling methods, the highest DNA concentrations were observed in samples isolated using filter-based kits, with a result of 6.465 μg/μL. In addition, an adequate level of purity is achieved with this method. In addition, thicker and lighter bands of DNA are observed, which can be attributed to the use of the enzyme Lyticase and other chemicals. The variability of isolation results can be affected by several factors, including extraction speed, sample type, extraction method, and environmental conditions. Technical errors during measurements can also affect the amount of DNA. In comparison, DNA isolation using filter-based kits for Candida albicans resulted in superior quantity and quality of DNA compared to cooling methods.

Abstract

Polymerase Chain Reaction (PCR) is an important technique to improve sensitivity in the detection of fungal infections, such as those caused by Aspergillus niger. The availability of pure DNA and DNA isolation techniques are important factors in implementing PCR. This study aims to compare the quality and quantity of DNA isolation of Aspergillus niger using the Filter Based Kit method and cooling. The experimental research design was used with a qualitative test of DNA isolate using Agarose Gel Electrophoresis (1.5%) and a quantitative DNA test using a UV-Vis Spectrophotometer (wavelengths of 260 nm and 280 nm). Data analysis compared the qualitative and quantitative results of DNA isolates from both methods. The results showed the presence of DNA bands in both isolation methods, with thicker bands in the Filter Based Kit method. The average concentration of DNA after isolation using the Filter Based Kit (6,478 ng/μl) was higher than that of the cooling method (5,994 ng/μl). The purity of DNA was also higher in the filter-based kit (1.7) than in the cooling method (1.1). The Filter Based Kit method contains chemical components that support the successful isolation of DNA. It can be concluded that the filter-based kit method produces Aspergillus niger DNA isolate with better quality and quantity than the cooling method. The implication of these findings is that the Filter Based Kit could be a better option for the isolation of Aspergillus niger DNA in laboratory applications.
