Hi all, while looking for SNPs for virus quasispecies in a badnavirus using RNA that was gel-excised with maximum length of 100, maybe 200 bp I find definitive read alignment hotspots to the master genome in all 3 samples. generally people have been finding these hotspots in the populations of siRNA of 21,22 or 24 nt length, products of silencing. however the hotspots I find are in the slightly longer reads. Sequencing ran for 36 cycles, so they are 36 nt long. Also, 90+% of these reads with potential lengths between 30 and 100 nt are aligning to the sense strand. I am trying to come up with an explanation for these two things and drawing a blank. I am not a virologist or even microbiologist, so am I missing something obvious? I apologize if this is not the place to ask this question, and would appreciate any answers or other places to ask this question.

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
