    Library insert size

    Hi There,

    I am aiming to sequence bacterial genome with NexteraXT 300bp paired-end reads. I have made my library and all the fragments size (including the adapter) are ranging from 200-650 (I check with the bioanalyzer and gel). Do you think that I will have sufficient insert size in the end? Do you think that I will have good insert size for clustering on the MiSeq platform (using Nextera v3 chemistry)?

    Would be very helpful of your suggestions here!

    Cheers,

    Shimul

    Insert sizes will be around 50-500 bp and most of sequenced fragments will be from shorter inserts and their abundance will depend on size distribution of library fragments. Library should cluster and sequence fine but you will not benefit from the long reads. To sequence larger fragments library fragments should be 600-1500 bp.

        Hello,

        I am finally running of my sample on the Miseq using MiSeq V3. I have checked the machine now and it shows that after 70 cycles, the >=Q30 is 96%, cluster passing filter 91.4%, and the cluster density is 1092K/mm.

        Do you think that the run is going well?

        Hope to hear back from you soon again!

        Cheers,

        Shimul

          Those numbers are good, so the run is probably going well.

              @Shimul, it is not necessary to post the same question multiple times on the forum. Your run metrics look good.

                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...

                Love this - good data definitely starts from good input, and poor input can only give relatively poor data. I particularly like the mention of Nanodrop/absorbance based methods for quantification. It's such a toss up if you'll get an accurate reading or what amounts to a randomly generated number, and a lot of library/sequencing related issues can be traced back to poor quant.
