The frag buffer will have a 1x concentration of ~10 mM Zn2+. This is pretty high so I think any amount of EDTA that might get co-precipitated will be very low and probably not worth worrying about.

Originally posted by Tulay Bayram View PostHi everybody,
Is anybody familiar with the fragmentation buffer below? I need to know the proportion of the below. This is what I 've found in a paper. I am trying to get fragments of about 200 bp excluding the adapters for SOLID sequencing. mRNA was fragmented at 82 degrees for 2 minutes..
Does anybody have any ideas ?
40mM Tris-acetate
100 mM Potassium acetate
31.5 mM Magnesium Acetate
pH 8.1

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...-
