DNA methods have resulted in improved renal allograft survival rates in cadaveric renal transplantation. This paper describes the impact of DNA typing by PCRSSP on a living related renal transplant (LRRT) programme. It evaluates error rates in serology, acute rejections, graft function and survival rates between the two typing methods. Serological typing was done on CTS 120 antisera Class 1 and...

We have adapted a method of amplifying and sequencing genomic DNA (1) for rapidly identifying and partially sequencing genes or transcripts from members of a multi-gene family in which one end is conserved and the other end is highly variable. By utilizing nested, conserved sequence primers in conjunction with primers specific for 6 bp restriction enzyme recognition sequences in a PCR, a family...

We used PCR to differentiate species in the genus Phytophthora, which contains a group of devastating plant pathogenic fungi. We focused on Phytophthora parasitica, a species that can infect solanaceous plants such as tomato, and on Phytophthora citrophthora, which is primarily a citrus pathogen. Oligonucleotide primers were derived from sequences of a 1,300-bp P. parasitica-specific DNA segmen...

Tobacco mosaic virus (TMV) is one of the devastating plant viruses in the world that infects more than 200 plant species. Movement protein plays a supportive role in the movement of other plant viruses, and viral coat protein is highly expressed in infected plants and affects replication and movements of TMV. In order to investigate genetic variation in the terminal fragment sequence in Iranian...

We attempted to produce primer-dimers (PDs) from a variety of primers with differing types and extents of complementarity. Where PDs were produced they were cloned and sequenced. We were unable to produce detectable PDs either with individual primers alone or with similar sequence primers even if they had 3'complementarity. These observations led to the hypothesis that a system could be develop...

We established a specific genotyping assay for HLA-A*01, which is one of the most frequently found HLA-A alleles in the Caucasian population. This assay uses the polymerase chain reaction (PCR) with allele group-specific primers (ASP). HLA-A*01 group-specific primers were designed for exon 3 of the HLA-A gene, based on the recent HLA-sequence alignment. Both sense and anti-sense primers were de...

Background: Meat species adulteration has become a problem of concern. This study aimed to compare two previously published multiplex Polymerase Chain Reaction (PCR) methods for meat species authentication.  Methods: The primers used in the first multiplex PCR involved species-specific reverse primer for sheep, goat, cattle, pig, and donkey with universal forward primer. In the second multiple...

BACKGROUND Severe and potentially fatal hypersensitivity reactions to drugs, particularly antiepileptics, are clinically unpredictable. Recent evidence has revealed a strong and specific association between the implicated drug, the type of adverse reaction, and the particular HLA genotype. An urgent need exists for rapid diagnosis of HLA status to guide drug prescription; however, traditional H...

A novel coronavirus, severe acute respiratory syndrome (SARS)-associated coronavirus (SARS-CoV), has been identified as the causal agent of SARS. Spike (S) protein is a major structural glycoprotein of the SARS virus and a potential target for SARS-specific cell-mediated immune responses. A panel of S protein-derived peptides was tested for their binding affinity to HLA-A*0201 molecules. Peptid...
