  • Tapestation or Fragment analyzer

    I am now about to buy tapestation of agilent or fragment analyzer of AATI

    I will use both to QC libraries genomic DNA and RNA

    We will not process many samples a week but we need a reliable low maintenance machine
    What would you recommend? Do you have any clear bias towards any one of them? why

    We only have the bioanalyzer. I think it is preferable for us because the high sensitivity chips are more sensitive than the tapestation.
    That said, the down side of a bioanalyzer is that you have to run samples 10-12 at a time. So if you only have a couple of samples to run the reagent costs become quite outrageous. And the kits themselves have a limited shelf life, so that can make the cost even worse if you don't run the instrument fairly heavily.

      I am making the same decision between a tape station and a AATI fragment analyzer. What did you end up deciding on this and why? Any information helps. Thank you!

        I chose tapestation

        It is much easier to operate. Other members of the department were very negative about the fragment analyzer.

          Why not a Labchip GX? It can run 96-well plates of samples and can perform regular NGS quant as well as genomic DNA assays.

            Really? Did you run any samples? The TapeStation is easier to use than the Fragment Analyzer for small sample sets, but the benefits stop there. Data quality matters most. The lack of resolution, sensitivity, and dynamic range will limit applications and worse, force you to keep using slab gels and the BioAnalyzer you hoped to get away from.

            See the attached restriction digest comparison of the TapeStation versus the Fragment Analyzer. Data speaks volumes, resolution is critical for sizing accuracy.

            NGS read lengths are getting longer and longer. If you demo the two also explore sensitivity limitations for samples over 2 kb.

              I have used the BA a lot in the past and recently switched to the TapeStation. For convenience, it is pretty simple and accuracy is good enough to use for NGS library prep. My previous lab was using it for hundreds of clinical samples, after calibrating it with a BA. It also gives you the option between running a few or many samples, which can lead to reduced costs against the BA. If you run without a ladder and use expired tapes (they only last 2 weeks after first use), you can really cut down costs.

              On the flip side, you can buy around 3 BA's for 1 TapeStation and the per sample cost may be higher (off the top of my head ~$41 for 16 sample D1000 tapes/reagents, $65 for HSD1000 tapes/reagents vs ~$30? for 1 x 12 sample BA D1000 chip/reagents). I also do notice the resolution loss between the BA.

              Someone else in our group was an advocate of the LabChip GX, but she said prep time was ~50 minutes vs 10 minutes for the BA and about 5 minutes for the TapeStation. You can have results for the TapeStation in as few as 10 minutes vs 30 for the BA. That can certainly help with development.

              No one that I know has experience with the Fragment Analyzer, but I do know we had one sitting idle, while BA's and TapeStations were being used frequently...

              Some of the major downsides have been that with only 25 - 1000bp resolution for the D1000, some samples may bleed into the ladder and give inaccurate concentrations. The BA offered a chip with up to 7500bp.

              We have used the gDNA tape only once and it was good enough to check the overall integrity, plus gave a DIN number for accuracy. Based on seqdx, if you need the resolution, it looks like that might be a problem.

                New tape station, 4200, to be released soon, likely shipping in September. May be wise to wait and see what the offer is....

                Looks like it will be capable of running 96 samples in "walk away" mode.

                  Yeah, my boss said a new one was coming out that would do 96 samples. Good to hear details.

                    The comment about Labchip GX prep time is silly. I have used both the BA and the GX, and the latter requires less hands-on work and skill.

                    You would get to 50 min only if you take into account that you have to put the chip and reagents on room temp half an hour before using them.
                    Not to mention that you prep the chip once and then it's good for the whole day. You just add samples to the microplate. That certainly helps with development.

                    And I absolutely love the GX software.

                      So same as BA and TapeStation + 20min prep. What's the per sample cost of the LapChip GX with reagents/chips?

                        Unless you will have a very low throughput in the lab (i.e. always less than 10 samples per day), the reagents cost should be considerably lower on the GX. But the initial investment in the instrument is higher.

                          Agilent should focus on the resolution and sensitivity limitations of the TapeStation. The instrument simply lacks the resolution needed for accurate sizing of large NGS libraries, and the lack of sensitivity for samples over 2 kb make it useless for single-cell applications such as Fluidigm C1 transcriptomics (Clonetech). Why spend hard earned capital funds on a system that can't handle the diverse assay requirements of a rapidly evolving field.

                            Oh really? Any idea when this is coming out?

                              Looks like it is already available: http://www.genomics.agilent.com/en/p...questid=859015

                                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...

                                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...
