We have been preparing libraries for Illumina GA and we have some problems with RNA-seq libraries. The issue that we are having is that we are seeing two peaks in bioanalyzer data (attached ppt). We are seeing this in all our RNA seq samples - no matter what organism used. We are using Illumina RNAseq kit. have anyone seen something like this? I would really appreciate any advice.

has anyone tried to do two rounds of DSN normalization (specifically for RNA-seq)? If so, how did you do it and how did it go? Thanks.

We are also seeing double peaks in our RNA-seq library preps, even though all samples have been gel extracted at 350bp. Does anyone know how it is possible to still have 700 bp fragments after gel extraction and what we can do to remove the longer fragments? Thanks.

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

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...-
