Remnants of retrotransposons in human genome?

Evolution is unaimed changes in time that a genome is shaped by a collection of random mutations, recombination, integrations, and reorganizations. Transposable elements (TEs) are mobile fragments representing a major portion of most eukaryotic genomes, and are therefore considered as a key player in evolution. They are one of the main sources of genetic variability and have a large impact on genome structure and stability in eukaryotes.

Label-free lateral flow assay for Listeria monocytogenes by aptamer-gated release of signal molecules.

Lateral flow assay (LFA) type of biosensors have been popular due to cost-effectiveness and easy-interpretation for instant results, most common examples of applications being pregnancy tests, food safety or medical diagnostics. There are several examples of reports with high sensitivity, including pre-concentration of the sample by magnetic pull-down. However, sensitivity and direct detection designs with aptamers has been a limiting factor for developing aptamers-based LFA assays.
