Human forensic casework requires sensitive quantitation of human nuclear DNA from complex sources. Widely used commercially available systems detect both nonhuman and human primate DNA, often require special equipment, and have a detection limit of approximately 0.1ng. Multicopy Alu elements include recently integrated subfamilies that are present in the human genome but are largely absent from...

Background: Hypercoagulability and hypofibrinolysis are among the symptoms exhibited by diabetic patients. Our study aimed to address the polymorphic nature of Alu DNA fragment in the human tissue plasminogen activator gene within diabetes mellitus (DM) Jordanian patients. Methods: Genomic DNA was isolated from 76 DM patients and 60 non-diabetic Jordanian individuals, and the Alu fragment was a...

BACKGROUND Quantification of integrated proviral HIV DNA by repetitive-sampling Alu-HIV PCR is a candidate virological tool to monitor the HIV reservoir in patients. However, the experimental procedures and data analysis of the assay are complex and hinder its widespread use. Here, we provide an improved and simplified data analysis method by adopting binomial and Poisson statistics. METHODS ...

By incorporating dUMP residues into the 5' end of PCR primers, one can generate products which, after treatment with uracil DNA glycosylase (UDG), contain 3' overhangs. These overhangs can be annealed to vector molecules with complementary overhangs generated in a similar fashion and transformed directly into Escherichia coli without the need for ligase. We have tested this method of ligation-i...

Alu-PCR is a relatively simple technique that can be used to investigate genomic instability in cancer. This technique allows identification of the loss, gain or amplification of gene sequences based on the analysis of segments between two Alu elements coupled with quantitative and qualitative analyses of the profiles obtained from tumor samples, surgical margins and blood. In this work, we use...

We describe an integrated approach to largescale physical mapping using an Alu-PCR hybridization screening strategy in conjunction with direct PCR-based screening to construct a continuous yeast artificial chromosome map covering >20 mb in human chromosome 3, bands pl4-p21, composed of 205 loci, connected by 480 yeast artificial chromosomes, with average interlocus distance of 100 kb. We observ...

background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...

We have developed a simple two-dimensional YAC pooling strategy to facilitate YAC library screening via STS and Alu-PCR approaches. The method has been implemented using the human total genomic YAC library of Olson and coworkers, and its validity tested by isolation of many chromosomes 19- and 21-specific YACs. The Alu-PCR approach is notable in that it is hybridization-based, such that PCR pri...

Y alphoid primers in combination with Alu and LINEs primers generated new DNA fragments in polymerase chain reactions (PCR) on DNA from a Y-only somatic cell hybrid but not from X-only, 3-only, or 21-only hybrids. X alphoid primers used in a similar manner generated new DNA fragments from the X-only hybrid, and 1 of the primers (X2) also generated new DNA fragments on 3-only and 21-only hybrids...

A polymorphic Alu element belonging to the young Ya5 subfamily of Alu repeats located in the progesterone receptor gene has been characterized. Using a polymerase chain reaction (PCR)-based assay, the genetic diversity associated with the PROGINS Alu repeat was determined in a diverse array of human populations. The level of insertion polymorphism associated with PROGINS suggests that it will b...
