Analysis of Extracellular RNA by Digital PCR
The transfer of extracellular RNA is emerging as an important mechanism for inter-cellular communication. The ability for the transfer of functionally active RNA molecules from one cell to another within vesicles such as exosomes enables a cell to modulate cellular signaling and biological processes within recipient cells. The study of extracellular RNA requires sensitive methods for the detect...
متن کاملTemporal Trends in Metal Pollution: Using Bird Excrement as Indicator
Past mining and smelting activities have resulted in metal polluted environments all over the world, but long-term monitoring data is often scarce, especially in higher trophic levels. In this study we used bird (Parus major and Ficedula hypoleuca) excrement to monitor metal pollution in the terrestrial environment following 16 years of continuously reduced emissions from a copper/nickel smelte...

متن کاملEnhanced analysis of real-time PCR data by using a variable efficiency model: FPK-PCR
Current methodology in real-time Polymerase chain reaction (PCR) analysis performs well provided PCR efficiency remains constant over reactions. Yet, small changes in efficiency can lead to large quantification errors. Particularly in biological samples, the possible presence of inhibitors forms a challenge. We present a new approach to single reaction efficiency calculation, called Full Proces...
متن کاملIdentification of the first Transgenic Aquatic Animal in Iran by PCR-Based Method and Protein Analysis
In the recent years, there is evidence of training a red type of zebrafish which differs from wild-type in body color. There is not any document how it reaches to the ornamental fish farms of Iran but at first, it was a doubt it belongs to a morphotype or genetic modification (GM). First of all, a set primer was designed to validate zebrafish species. Mitochondrial 16srDNA was selected and ampl...
