What is the average coverage with good quality of whole genome sequence in read numbers (100 bp/read) and base pairs?

Based on these experiments and their callability calculations, the authors estimate that generating 50x mapped coverage (60x before read mapping/filtering are applied) renders ~95% of the genome and ~81% of the exome callable. Intriguingly, however, the authors note that they’d sequenced an unrelated sample using the latest HiSeq chemistry and basecalling software, achieving the same level of callability with just 35x mapped coverage. If anything, this emphasizes that (as the authors suggest), a “callability” metric is far more informative to report when describing the resequencing of human genomes.

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...04-04-2024, 04:25 PM -
Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...03-22-2024, 06:39 AM
