    454 junior user - hello everyone

    Hi everyone,
    I am Encarnita, french-spanish immunologist working in Japan.
    I am using 454 Lifescience Tech. since more than 3 years, but autonomously using 454 Junior since a year. I've been getting many good infos by surfing on that great forum , but I registered only recently !
    I've been suffering several troubles since I perform the 454 libraries preparation, emPCR and sequencing by my self, such as too few enriched beads, too much enriched, never-ending washing steps, few passed filter reads out of many raw reads, software upgrade issues leading to new setup after 12 successfull run....
    I have no experience on other platforms, but I am eager to learn and I really want to understand precisely what's going on with the 454 steps.
    I'll be pleased to help also, if I have any relevant info.
    All the best to seqanswers community !

    From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
    by SEQadmin2


    Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


    The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.

    Environmental Genomics in the Age of NGS: From Microbes to Conservation Strategies
    by SEQadmin2

    Studying ecosystems means dealing with complex, multi-species communities that are hard to observe at scale. This complexity, however, hides many important questions to be answered, from how biogeochemical cycles work and how climate change can affect species distribution to how conservation strategies can work best.


    Genomics, particularly since the expansion of NGS, has transformed ecosystem ecology. By sequencing environmental DNA, we can now assess biodiversity without direct...
