  • Can I load two DNA and two RNA samples to one HiSeq 2500 rapid mode flowcell?

    Is it technically possible? Or do I need to put them in two rapid mode flowcells?

    Thanks in advance.

    As long as the read type (single/Paired) and base length is the same, it doesn't matter what sample type is in any given lane.

    The only time it matters is in the processing what you align it to-genome or transcriptome.

      Yeah. That's what I thought. But a BGI staff told me that's not possible. Can it be due to different library sizes?

        It would be a problem to combine them into one lane as different sizes as they would not cluster equivalently, but separate lanes should be fine.

          Are the sequencing primers for the two libraries the same?

            Thank you for your reply. Two of them are exome and the other two are rna-seq. I presume these two sets are prepared differently but they should be at least be able to fit in two lanes. Let me call them and check again...

              Since there are two lanes per Rapid Run Mode flow cell, you may can try to load each type of library into each flow cell lane independently.

                I called BGI again. They said it is actually feasible but they haven't had any experience with the Truseq Duo Loading Kit yet, so that's why the rep answered that way.

                I consider my problem as solved. Thanks everyone for contributing.

                  Exploring the Dynamics of the Tumor Microenvironment
                  by seqadmin




                  The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...

                  Exploring Human Diversity Through Large-Scale Omics
                  by seqadmin


                  In 2003, researchers from the Human Genome Project (HGP) announced the most comprehensive genome to date1. Although the genome wasn’t fully completed until nearly 20 years later2, numerous large-scale projects, such as the International HapMap Project and 1000 Genomes Project, continued the HGP's work, capturing extensive variation and genomic diversity within humans. Recently, newer initiatives have significantly increased in scale and expanded beyond genomics, offering a more detailed...
