TLDR
The exquisite sensitivity of the polymerase chain reaction means DNA contamination can ruin an entire experiment and adherence to a strict set of protocols can avoid disaster.
Abstract
The exquisite sensitivity of the polymerase chain reaction means DNA contamination can ruin an entire experiment. Tidiness and adherence to a strict set of protocols can avoid disaster.

Randomised trial of lymphoblastoid α-interferon in chronic hepatitis C: Effects on inflammation, fibrogenesis and viremia

TL;DR: Interferon diminishes inflammatory and fibrogenic activity in the majority of patients with chronic hepatitis C and abolishes viremia in most of the patients with a sustained response, representing a long-term sustained remission of the disease.

Detection of Shigella dysenteriae type 1 and Shigella flexneri in feces by immunomagnetic isolation and polymerase chain reaction.

TL;DR: A combination of immunomagnetic separation (IMS) and a polymerase chain reaction (PCR) procedure was used for direct isolation and identification of Shigella dysenteriae type 1 and Shigellae flexneri from feces.

Hepatitis B virus DNA in sera and liver tissue of HBsAg negative patients with chronic hepatitis C.

TL;DR: In this paper, the authors determined the rate and explored the clinical significance of HBsAg negative HBV coinfections in Austrian patients with chronic hepatitis C. They found that HBV DNA was detected in 22% of sera and 19% of liver tissue specimens of patients who were negative for hepatitis B virus infection.

Enlargement of perihepatic lymph nodes in relation to liver histology and viremia in patients with chronic hepatitis C.

TL;DR: E enlargement of perihepatic lymph nodes in patients with chronic hepatitis C is predictive for the presence of severe inflammatory activity, and appears to be related to viral replication within the liver and the immune‐mediated inflammatory response of the host.

Primer-directed enzymatic amplification of DNA with a thermostable DNA polymerase

TL;DR: A thermostable DNA polymerase was used in an in vitro DNA amplification procedure, the polymerase chain reaction, which significantly improves the specificity, yield, sensitivity, and length of products that can be amplified.

Specific synthesis of DNA in vitro via a polymerase-catalyzed chain reaction.

TL;DR: A method whereby a nucleic acid sequence can be exponentially amplified in vitro is described in the chapter, and the possibility of utilizing a heat-stable DNA polymerase is explored so as to avoid the need for addition of new enzyme after each cycle of thermal denaturation.

DNA amplification for direct detection of HIV-1 in DNA of peripheral blood mononuclear cells

TL;DR: This method of DNA amplification made it possible to obtain results within 3 days, whereas virus isolation takes up to 3 to 4 weeks, and may therefore be used to complement or replace virus isolation as a routine means of determining HIV-1 infection.

DNA typing from single hairs

TL;DR: Three different means of DNA typing are used for the determination of amplified DNA fragment length differences, hybridization with allele-specific oligonucleotide probes, and direct DNA sequencing on single human hairs to detect genetically variable mitochondrial and nuclear DNA sequences.
Journal ArticleDOI

Amplification and analysis of DNA sequences in single human sperm and diploid cells

TL;DR: The use of the polymerase chain reaction for analysing DNA sequences in individual diploid cells and human sperm shows that two genetic loci can be co-amplified from a single sperm, which may allow the analysis of previously inaccessible genetic phenomena.
