Safflower ( Carthamus tinctorius L.) is currently being developed as a platform for the production of novel proteins. Methods for detecting and quantifying transgenic safflower are needed to ensure seed quality and to monitor for its adventitious presence. We developed and compared three methods of assaying for transgenic safflower presence in conventional seedlots: field bioassays, enzyme-link...
زمینه: استافیلوکوکوس اورئوس انواع انتروتوکسین خارج سلولی را تولید می نماید که سبب مسمومیت غذایی می شوند. روش های مختلفی جهت شناسایی سم تولید شده توسط این باکتری وجود دارد. به دلیل آن که شباهت آنتی ژنی زیادی بین انتروتوکسین ها وجود دارد، ممکن است همیشه نتوان از ارزیابی سرولوژیکی استفاده نمود. در این میان تست PCR، یک تست بسیار حساس و دارای اختصاصیت بسیار زیاد و سریع می باشد. این پژوهش با هدف ش...
Traditional diagnostic assays for Helicobacter pylori detection have their limitations. Molecular methods can improve both diagnosis and understanding of gastric diseases. Here we describe an in-house quantitative real-time polymerase chain reaction (q-rt-PCR) for the detection of H. pylori in gastric biopsies which has been developed and has a detection limit of 10 copies, the specificity of w...
A real-time quantitative polymerase chain reaction (Q-PCR) assay was developed for detecting and quantifying Escherichia coli in water samples from agricultural watersheds. The assay included optimization of DNA extraction and purification from water samples, and Q-PCR amplification conditions using newly designed species-specific oligonucleotide primers derived from conserved flanking regions ...
To assess the effect of various vaccine strains on replication and shedding of virulent Marek's disease virus from experimentally infected chickens, quantitative PCR (q-PCR) methods were developed to accurately quantify viral DNA in infected chickens and in the environment in which they were housed. Four groups of 10 chickens, kept in poultry isolators, were vaccinated at 1 day old with one of ...
Quantitative real-time reverse transcription-polymerase chain reaction (Q-PCR) has become an indispensable technique for accurate determination of gene expression in various samples. In mice, intravenous injection of concanavalin A (ConA) leads to acute hepatitis and liver injury. Functional studies based on this model have provided insights for understanding the mechanisms of liver injury. How...
