Abstract Rapid tests for active SARS-CoV-2 infections rely on reverse transcription polymerase chain reaction (RT-PCR). RT-PCR uses of RNA into complementary DNA (cDNA) and amplification specific (primer probe) targets using (PCR). The technology makes rapid identification the virus possible based sequence homology nucleic acid is much faster than tissue culture or animal cell models. However t...

background and objective: rapid diagnosis of pertussis is important for the timely isolation of the infection source and early prevention measures among the contact persons, especially among non-vaccinated infants for whom pertussis is life- threatening. materials and methods: targets is481 , is1001, bp0026 and human gapdh gene were used to develop a multiplex real- time pcr assay based on the ...

PCR technology offers alternatives to conventional diagnosis of Cryptosporidium for both clinical and environmental samples. We compared microscopic examination by a conventional acid-fast staining procedure with a recently developed PCR test that can not only detect Cryptosporidium but is also able to differentiate between what appear to be host-adapted genotypes of the parasite. Examinations ...

Technology: Polymerase chain reaction (PCR) Use: PCR is a highly sensitive technique that is used to amplify and detect small amounts of specific DNA sequences in biological material. It is made possible by the availability of specific DNA polymerases (e.g., Taq or Tth) that are produced by bacteria in hot springs. These thermostable enzymes allow for repeated cycles of denaturation and DNA syn...

The LightCycler is a rapid air-heated thermal cycler which incorporates a fluorimeter for the detection and quantification of Polymerase Chain Reaction (PCR) amplified products. It provides real-time cycle-by-cycle analysis of product generation. Amplification occurs in glass capillary tubes. The products are detected using a fluorescent double stranded DNA binding dye or fluorescent probes. Ho...

In the very beginning of polymerase chain reaction (PCR) tests entering the field of diagnosis of infectious agents, the introduction of this technology into routine diagnosis was hampered by its frequent tendency to create false-positive results because of contamination. This problem is now widely solved by the introduction of the uracil-N-glycosylase (UNG) anticontamination technology. Howeve...

Background: Bovine follicle stimulating hormone (bFSH) belongs to the family of glycoprotein hormones that are released from the pituitary gland or the placenta. This hormone is a heterodimer consisting of common α- and specific β-subunit. Bovine FSH is used for reproductive technology such as superovulation in farm animals and polycystic ovary syndrome treatment. Also this hormone is produced ...

microRNAs (miRNAs) are small RNAs that regulate translation and hence control a variety of cellular processes in metazoans. The quantitation and identification of miRNAs has been hampered by their small size and low abundance. Here we describe two robust PCR-based assays of miRNA expression based on the original cloning strategy. The non-quantitative PCR method allows detection and identificati...
