Construction Strategy for an Internal Amplification Control for Real-Time Diagnostic Assays Using Nucleic Acid Sequence-Based Amplification: Development and Clinical Application

Construction strategy for an internal amplification control for real-time diagnostic assays using nucleic Acid sequence-based amplification: development and clinical application.

An important analytical control in molecular amplification-based methods is an internal amplification control (IAC), which should be included in each reaction mixture. An IAC is a nontarget nucleic acid sequence which is coamplified simultaneously with the target sequence. With negative results for the target nucleic acid, the absence of an IAC signal indicates that amplification has failed. A ...

Sensitivity and Specificity of Nucleic Acid Sequence-Based Amplification Method for Diagnosis of Cutaneous Leishmaniasis

Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

1 2 Development of a Quantitative Real - Time Nucleic Acid 3 Sequence - Based Amplification Assay with an Internal 4 Control

Simple technique for internal control of real-time amplification assays.

BACKGROUND In real-time PCR assays, the most accurate way to identify false-negative results, e.g., those caused by PCR inhibitors, is to add to samples an internal control that will be coamplified with the target (e.g., pathogen) DNA. Current internal control procedures, however, which usually involve the introduction of a DNA fragment, are complex, time-consuming, and expensive. METHODS Sin...
