    16S rRNA amplicon multiplexing on MiSeq

    How many samples can I run in a multiplex to get 'enough' reads per sample with an amplicon size of about 300 bp? Is there a formula to calculate this based on sequences generated per run, amplicon size and coverage?

    Here is a coverage calculator from Illumina: http://support.illumina.com/download...alculator.ilmn There is a tech note included for the coverage calculation.

    An application note for 16s sequencing: http://res.illumina.com/documents/pr..._miseq_16s.pdf

    I will let someone else comment on what qualifies as "enough" reads.

      Thanks. The 'enough' questions is maybe more a good discussion point.

        960 (10 plates of barcoded primers) using v2 2x150bp

        here's the protocol: http://www.earthmicrobiome.org/emp-s...protocols/16s/

          You can use the Coverage/Read calculator here: https://genohub.com/shop-by-next-gen...e7a8918f19251a I entered 960 samples at 30,000 reads/sample. Feel free to change those to fit your experiment.

            What is the typical library concentration that people are using on the MiSeq? We are currently using 7 pM and getting ~800 k/mm2. Can we push this higher?

            Thanks

              Beyond CRISPR/Cas9: Understand, Choose, and Use the Right Genome Editing Tool
              by SEQadmin2



              CRISPR/Cas9 sparked the gene editing revolution for both research and therapeutics.1 But this system still showed severe issues that limited its applications. The most prominent were the heavy reliance on PAM sequences, delivery limitations, double-stranded breaks that prompt unintended edits and cell death, and editing inefficiency (both in targeting and in knock-in reliability).

              Despite this, “CRISPR helped turn genome editing from a specialized technique into

              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.

              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.
