  • PGM CHIP loading problem

    This is the chip i have loaded today.I'm confused why the loading is so bad.As you see in the image,the upper half is so dense,the lower half is so sparse.can anyone tell me the cause?Thanks!

    Newbie here, and I actually use an Ion Proton - but how likely is it that the chip wasn't dry when you loaded the ISPs? It looks like the sample entered the chip by displacing another solution - in this case the two blue "vortexes" and the bottom part of the chip would be where the solution lingered.
    Alternatively... a warped chip, perhaps?

        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...

        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...
