armillaria root and crown rot is an important disease of woody plants including fruit, forest and ornamental trees in different regions. the disease is common in isfahan and causes economical losses on a broad range of fruit trees. there only a few tolerant varieties to disease, and there is no efficient method in controlling the disease. therefore, detection of the pathogen from soil is necess...

self etching primers, due to ease of manipulation, have been extensively used in recent years. these self etching primers containing a relatively weak acid, may not provide an optimal bond strength. the purpose of the present in-vitro investigation was to evaluate the effects of 37% phosphoric acid application prior to applying self etching primers on composite bond strength. in this experiment...

OBJECTIVE The objective of this study was to analyze different primers that are commonly used in epidemiological studies for the detection of Leishmania DNA by PCR, and to compare them to the conventional direct parasite search for American cutaneous leishmaniasis (ACL) diagnosis. MATERIAL AND METHODS Five pairs of primers, four of them derived from Leishmania kDNA sequences (MP3H-MP1L; B1-B2...

Multiplex quantitative PCR based on novel design of fluorescent primers is described. Fluorogenic primers are labeled with a single fluorophore on a base close to the 3' end with no quencher required. A tail of 5-7 nt is added to the 5' end of the primer to form a blunt-end hairpin when the primer is not incorporated into a PCR product. This design provides a low initial fluorescence of the pri...

PrimerStation (http://ps.cb.k.u-tokyo.ac.jp) is a web service that calculates primer sets guaranteeing high specificity against the entire human genome. To achieve high accuracy, we used the hybridization ratio of primers in liquid solution. Calculating the status of sequence hybridization in terms of the stringent hybridization ratio is computationally costly, and no web service checks the ent...

A highly sensitive nested reverse transcriptase-PCR assay, with primers derived from the prostate-specific antigen (PSA) and prostate specific membrane antigen (PSM) cDNA sequences, has been used to detect occult hematogenous micrometastatic prostate cells. In 77 pa tients with prostate cancer, PSM and PSA primers detected circulating prostate cells in 48 (62.3%) and 7 (9.1 %) patients, respect...

The caption for Figure 5 reads: One-color SNV quantification. (A) Primers are designed with the single nucleotide variant at the 3′ end of the complementary region. Noncomplementary tails of varying lengths are then added to the 5′ end and amplified with a universal reverse primer. (B) 1:4 mixture of MUT/WT BRAF template amplified with mutant primers with the short tail and wild-type primers wi...
