The polymerase chain reaction (PCR) is an easy, economic, convenient and biochemical technology in molecular biology for the amplification of thousands to millions of copies of a particular DNA sequence. The method consists of repetitive cycles of three steps: denaturation, hybridization, and polymerase extension, that raising temperature to break hydrogen bonds for formation of the single stra...

Diarrhea in cattle is one of the most economically costly disorders, decreasing milk production and weight gain. In the present study, we established a novel simultaneous detection system using TaqMan real-time PCR designed as a system for detection of microbes from bovine diarrhea using real-time PCR (referred to as Dembo-PCR). Dembo-PCR simultaneously detects a total of 19 diarrhea-causing pa...

Improvements in detection limits/sensitivity and lower sample consumption are potential benefits of reducing PCR reaction volumes used in forensic DNA typing of crime scene samples. This premise was studied first with experimental mixtures and a nine-loci megaplex, which demonstrated stochiometric amplification and accurate detection. Next, adjudicated casework samples were subjected to amplifi...

Contagious equine metritis (CEM) is a highly contagious bacterial venereal disease of horses caused by Taylorella equigenitalis. CEM-PCR is a semi-nested PCR method for detecting this bacterium. Although this technique is regarded as a sensitive diagnostic method for CEM, there are risks of it generating false positive and false negative results. In this study, we constructed a recombinant plas...

The use of trade, firm, or corporation names in this protocol is for the information and.jor consideration in designing a nested PCR protocol compatible with quantitation is to assure that the maximum concentration of PCR products produced by the....

Pada masa pandemi Covid-19, teknik penggandaan DNA dengan metode Polymerase Chain Reaction (PCR) menjadi gold standard untuk diagnosis virus dan penghitungan sampel klinis. Metode PCR ini diimplementasikan pada alat nama Thermal Cycler atau mesin PCR. Salah satu komponen utama dalam adalah pemanas. Tiga buah pemanas, yakni: Peltier Device 12715, Ceramic Heater PTC 12 VDC, Customized VDC diuji k...

DNA amplification by polymerase chain reaction (PCR) should be inhibited if the target for amplification region in the template DNA is nicked or cut. Based on this premise, we established a sensitive and differential assay using PCR to detect antibiotics that act on DNA. After template lambda DNA (10 pg) was incubated with antibiotics (10 approximately 20 ng) at 37 degrees C for 30 minutes in a...

The effects of 5 factors (template DNA, Mg(2+), dNTPs, Taq DNA polymerase, and primer) on the polymerase chain reaction (PCR) were investigated to optimize the start codon targeted polymor-phism (SCoT)-PCR system of Dactylis glomerata L., using an orthogo-nal design L16 (4(5)). A suitable SCoT-PCR system for D. glomerata was established; the 20 μL reaction volume contained 3.0 mM Mg(2+), 0.2 mM...

Polymerase chain reaction (PCR) provides a foundation for simple sequence repeat molecular marker-assisted selection (SSR MAS) in soybean. This PCR system and its various conditions have been optimized by many researchers. However, current research on the optimization of the PCR system focuses on double-primer PCR products. We compared single- and double-SSR primer PCR products from 50 soybean ...
