  • What is the minimum coverage needed?

    Hi, (my very firs post here on this helpful forum

    I have performed an experiment where I have placed individuals (from the wild) into new a environment, then I have sampled the individuals at different time points. I also have controlls for all the time intervals (individuals taken out of its common environment and placed back to similar conditions).
    My plan is to sequence the mRNA on Illumina, potentially on a HiSeq2000 (but there is also a GA2 available).

    I would be happy to get some suggestions reagrding coverage depth needed in order to aim at a certain number of individuals per lane (trying keeping the cost down). I am interrested in detecting active genes during a specific period in a defined environment, and to then, compare between different time stages. My study organism has about 21 000 genes, with a total of about 36Mb, and the genome has been sequenced (so I have a refrence genome). My plan is to go with paired end reads, and 50 or 75 bp.

    Thanks in advance, this is all very new to me so all suggestions are welcome

    Essential Discoveries and Tools in Epitranscriptomics
    by seqadmin


    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 on Modified Bases...

    Current Approaches to Protein Sequencing
    by seqadmin


    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...
