Limitations and challenges of genetic barcode quantification [PDF]

Scientific Reports, 2017
AbstractGenetic barcodes are increasingly used to track individual cells and to quantitatively assess their clonal contributions over time. Although barcode quantification relies entirely on counting sequencing reads, detailed studies about the method’s accuracy are still limited.

Combining multiple markers significantly increases the sensitivity and precision of eDNA‐based single‐species analyses

Environmental DNA, 2023
The analysis of environmental DNA (eDNA) is becoming integrated as an established biomonitoring tool, often characterized by detection limits exceeding those of conventional counterparts. However, further improving the sensitivity of these methods may be

Limits of Fat Quantification in the Presence of Iron Overload [PDF]

Journal of Magnetic Resonance Imaging, 2021
BackgroundChemical shift encoded magnetic resonance imaging (CSE‐MRI)‐based tissue fat quantification is confounded by increased R2* signal decay rate caused by the presence of excess iron deposition.PurposeTo determine the upper limit of R2* above which it is no longer feasible to quantify proton density fat fraction (PDFF) reliably, using CSE‐MRI ...

A statistical model for calibration and computation of detection and quantification limits for low copy number environmental DNA samples

Environmental DNA, 2021
Environmental DNA (eDNA) has been increasingly utilized by academic, industry, and government groups for environmental monitoring due to its efficiency in regards to both time and cost, as well as non‐invasiveness to target organisms, and reduced ...
