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.

Comparison of Six PCR Methods Using Peripheral Blood for Detection of Canine Visceral Leishmaniasis

TL;DR: Comparisons of the sensitivities and reliabilities of different PCR methods for the diagnosis and epidemiological study of canine visceral leishmaniasis using dog blood allow the discussion of the advantages and drawbacks of highly sensitive versus moderately sensitive PCR methods in diagnosis and prevalence studies of CVL.
Journal ArticleDOI

Prevalence of hepatitis C virus infection in patients with lymphoproliferative disorders.

TL;DR: The close association between HCV infection and EMC is confirmed, and evidence is provided that the pathological substrate of EMC corresponds to the immunocytoma in HCV-positive lymphomas clinically behave as essential mixed cryoglobulinemia.
Journal ArticleDOI

Immunological significance of cytotoxic T lymphocyte epitope variants in patients chronically infected by the hepatitis C virus.

TL;DR: Interestingly, follow up analysis over a period of up to 46 mo revealed that, in contrast to the relatively high frequency of escape variants initially observed, the subsequent emergence rate of CTL escape variants was very low.

Prenatal sex determination by DNA amplification from maternal peripheral blood

TL;DR: The polymerase chain reaction was used to amplify a Y-specific repeat sequence in peripheral blood DNA samples from 19 pregnant women to assist prenatal diagnosis of sex-linked genetic disorders.

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.
Book ChapterDOI

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.

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.
