Im in the initial stages of planning a miRNA seq experiment using human cultured cells and decided on TRIzol extraction, Truseq small RNA prep kit, using an illumina HiSeq2500. The illumina webinar suggests 10-20 Million reads for discovery, the QandA support page suggests 2-5M, and I wrote the tech support to ask, who suggested I do up to 100M reads for rare transcripts. Exiqon guide to miRNA discovery manual says there is not really any benefit on going over 5M reads. I was hoping to save money by pooling more samples in a lane, so I was hoping someone with experience might be able to suggest a suitable number of reads.

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...04-22-2024, 07:01 AM -
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
