HLA-A*02 is a class I major histocompatibility complex (MHC) allele which is part of the HLA-A group of human major histocompatibility complex (MHC) leukocyte antigens (HLA). HLA-A is a human MHC class I cell surface receptor and is involved in presenting short polypeptides to the immune system. These polypeptides are typically 7-11 amino acids in length and originate from proteins being expressed by the cell. Cytotoxic T cells in the blood "read" the peptide presented by the complex and should only bind to non-self peptides. If binding occurs, a series of events is initiated culminating in cell death via apoptosis. Hepatitis B virus (HBV) polymerase is a multifunctional enzyme that can use both RNA and DNA as a template for amplification and also has an RNase H function. First the polymerase acts on the HBV pre-genomic RNA (pgRNA) to reverse transcribe it to form the (-) DNA strand. Simultaneously the RNA template is degraded by the polymerases RNase H activity, except for a stretch of RNA at 5' end of the pgRNA which is used to prime the synthesis of the (+) DNA strand. This process results in a new partially double-stranded relaxed circular DNA molecule (rcDNA) within a new capsid.

Caroverine is an anti-inflammatory drug that belongs to the group of non-steroidal anti-inflammatory drugs. It is structurally related to the amino acid glutamate and has been shown to inhibit primary sclerosing cholangitis, a chronic inflammatory bowel disease. Caroverine has also been shown to be effective in the treatment of myocardial infarcts and analytical methods have been developed for its determination in plasma. The polymerase chain reaction (PCR) is a technique that can be used for the detection of caroverine in biological samples. This reaction is based on the amplification of DNA from a small amount of starting material and requires biocompatible polymers as primers. Caroverine can also cause side effects such as stomach pain, diarrhea, nausea, and vomiting.

6-Carboxyfluorescein is a fluorescent dye widely used in PCR methodologies. It is used to label the 5’ end of oligonucleotides as a reporter in the presence of a quencher at the 3’ end (dual labelled probe). During amplification, the dye is cleaved, and the fluorescence increases proportionally with the amount of the specific sequence amplified during the PCR process. The development of the fluorescence signal is therefore specifically related to the amplification of the target sequence. It is used to tag DNA and RNA for in vivo and in vitro applications, as well as for structural studies and RNA-protein interactions. 6-Carboxyfluorescein that has NHS-activated carboxylic acids can react with primary amines. 5’-reporter used in RT-PCR for COVID-19 diagnosis by HKI; Institute Pasteur; Charité; CDC, USA; CDC, China; NIID and NIH. (ex/em: 495/517nm in DMSO or DMF at pH > 9.0)

Metamizol sodium monohydrate is a nonsteroidal anti-inflammatory drug that is used as an analgesic and antipyretic. Metamizol sodium monerate is metabolized in the liver via cytochrome P450 (CYP) to form metamizole. It has been shown to inhibit chemiluminescence of polycyclic aromatic hydrocarbons using a dipyrone-treated biological sample, and the rate constant for this inhibition has been determined by the use of a chemiluminescence method. An analytical method for metamizol sodium monohydrate has also been developed using polymerase chain reaction (PCR) amplification of DNA sequences from human squamous cells, which can be used for forensic purposes. Metamizol sodium monohydrate has shown anti-inflammatory activity against rat paw edema and carrageenan-induced inflammation in rats, but it can cause side effects such as dizziness, drowsiness, headache, nausea,
