    454 Library / Emulsion / Instrument Protocols (October 2008)

    Three protocol PDFs attached that I stumbled upon on the web, I thought some of you may be interested.

    These documents are of a great help.
    Do they exist for the other instruments?


    C'mon Mr Illumina and Mr AB, we need some information like your friend's Mr Roche.

      cDNA from Evrogen with Ti

      Has anybody had any experience with Ti sequencing Evrogen Trimmer Direct cDNA? For a 2 region Ti, we got 67 Mb and only 20% pass. The support people feel it is a problem in the emulsion PCR. Any help would be much appreciated. We've sequenced ~30-40 similar samples with FLX and no problems (over 100 Mb, ~440,000 reads per run).

        Hello, I´m user of a 454 Flx system and I´ll use PTS (Parallel Tagged Sequence) and Selector Technology to sequencing 18 kbp of targeted genomic DNA from 500 samples, any ideas are wellcome!!
        Thank you for the three protocol pdf!

          Pts

          Hi, hope your PTSequencing worked well. How did you sort out the data? I tried using AVA software to process my untagged reads and had problems. Any ideas appreciated.
          Thanks.

                hey Stella,

                you got mail!
                see you in Edinburgh!

                Is Nicola already on her maternity leave?

                      PTS Wisdom?

                      Hi
                      We are currently working on de novo RNA-seq and re-sequencing in a pre-genome species (onion) and are interested in PTS or a similar generic barcoding approach to enable us to do population genetic studies.
                      If anyone can give me any opinion or advice concerning this approach I'd be really grateful. To date we are just working with barcoded primers

                      Regards
                      John

                        Hi
                        We are trying to work out cDNA sequencing using 454, but Titanium did not work, and Standard was severely affected by polyA tail despite the nice profile of the sstDNA library.
                        We used Dynabeads for mRNA purification, and Stratagen Just cDNA kit for ds cDNA synthesis (1st strand primed by none-anchored oligo dT from the kit). Our samples tend to have long polyA tail, and we found 454 sequencing cannot tolerate this.
                        We are trying anchored dT primer now, but would appreciate any suggestion, such as choice of kit, 1st strand priming method (dT vs random primer?), or any tips in improving library constrcution for greater chance of success in sequencing?
                        Thank you.

                            re Poly A etc

                            We have had very nice results from Ti sequencing of normalised cDNA prepared using Evrogen Mint + Trimmer kits, using a modified 3' Primer XXXXXXXXXXX(T)4G(T)9C(T)10VN as described by Beldade et al.

                            The information posted at http://www.cees.uio.no/research/faci...equencing.html was very useful.

                                Proteomic Platforms: How to Choose the Right Analytical Strategy to Improve Detection and Clinical Applications
                                by SEQadmin2


                                Proteomics platforms are evolving rapidly, with advances in mass spectrometry and affinity-based approaches expanding what researchers can detect and at what scale. As the field moves toward deeper proteome coverage and clinical applications, scientists face an increasingly complex landscape of tools. This article will explore how researchers are navigating these choices to find the right platform for their work.

                                The systematic characterization of the human proteome has

                                Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
                                by SEQadmin2



                                Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

                                Cancer Drug Resistance: The Lingering Barrier to Rising Survival
                                by SEQadmin2



                                Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

                                There is no single reason why many patients don’t respond to treatment as expected. Cancer is...
