  • best primers for 16S amplicon sequencing

    Hello All
    We are starting a metagenomics project to identify mixed bacterial populations in various biological specimens. Any suggestions for robust 16S primers?
    Ideally, something that has been successfully used with the GS-FLX platform and contains the necessary key, A/B and possibly MID sequences.
    Thanks!

    David,

    Have a look at what the folks at the Ribosomal Database Project have done with multiplexed primer design for 16S amplicon sequencing:

      Check out the papers from Mitch Sogin's group in woods hole- lots and lots of info on 16s amplicon sequencing using 454.

        The designs here look optimized for GS-FLX standard chemistry. (~210 base amplicons and 6 or 8 base barcodes). Anyone done a redesign to take advantage of longer Titanium reads?

          Titanium primers

          The HMP DACC has some info on primers and bar codes that were used for titanium 454 sequencing - http://www.hmpdacc.org/sops.php

          They were looking at V1-V3 and V3-V5 regions.

          Edit: They reorganized their web site, the proper url is: http://www.hmpdacc.org/tools_protocols.php#sequencing

            And also check

              For longer barcodes for titanium, Fierer 2008 PNAS has a good set http://www.pnas.org/content/early/2008/11/12/0807920105 we're using these with the human microbiome project primers (their barcodes are a couple of different lengths, I prefer Fierer's as the length is standard).

                primers for GS Junior

                Hi everyone

                I am currently busy with a new metagenomics project that requires 16S and 18S rRNA pyrosequencing. However our new sequencer, the GS junior, I am told uses different adapter sequences to the FLX titanium etc. Does anyone know where I might find a tried and tested set? Full sequences. Also the RDP database gives a list of 8 base and 6 base barcodes, however our sequence technician insists on using roche's 10 base barcodes making the primers long without actually attaching the specific 16/18S primer....And our normal 16S primers that amplify the V3 region of the 16S forms hairpins with the adapter sequencing and causes mayor primer dimers...

                help please please....

                  We've finally got a publication out that details v6v4 Ti amplification and one in press for v3v5. Better than the HMP (single primer) versions.

                    The guys at Silva (bigger and better aligned 16S database than the other alternatives) have done an exercise checking out all the 16S primers they could get their hands on.

                    Paper published here http://nar.oxfordjournals.org/conten...ar.gks808.full

                    We have adapted versions of the HMP V3-V5 primers here http://www.plosone.org/article/info%...l.pone.0032543 which perform well and using the criteria in Silva paper are both greater than 90% coverage for bacteria.

                    More important in some ways is knowing how the primers you pick perform with your particular sample type. We know ours aren't so hot on Mycobacteria for example, so for projects where that's an issue we can swap them out or use specific assays for those bugs within the community.

                    Also, it's not always about phylogenetic coverage - some great coverage primers give rubbish yields in PCR, so you have to deal with large numbers of samples dropping out.

                      ​​​​​​The introduction of single-cell sequencing has advanced the ability to study cell-to-cell heterogeneity. Its use has improved our understanding of somatic mutations1, cell lineages2, cellular diversity and regulation3, and development in multicellular organisms4. Single-cell sequencing encompasses hundreds of techniques with different approaches to studying the genomes, transcriptomes, epigenomes, and other omics of individual cells.

                      Single-cell sequencing is a technique used to investigate the genome, transcriptome, epigenome, and other omics of individual cells using high-throughput sequencing. This technology has provided many scientific breakthroughs and continues to be applied across many fields, including microbiology, oncology, immunology, neurobiology, precision medicine, and stem cell research.
