  • User-performed maintenance on GS-FLX+

    We are getting ready to do our first switch out of filters and pump tubing on our GS FLX+. Has anyone given this a go yet? Any tips? We've had such a bad year with ours that I am hesitant to give it another reason to act up.

    We had ours replaced once already but our FAS came to the lab and did it for us. It seemed fairly simple, actually simpler than I thought. Next time I think we will do by ourselves.

      Seems easy enough, but they send out my service engineer to do it. I think there is a video on the my454 website showing how to do it.

        Thanks to both for the reply.
        Yes - I've watched the video and I think it will be do-able - no one offered up front to send anyone to do it so I'll just give it a go - just wondering if there were any snags I might run into.
        As I said - this has not been a good year for this machine and I hate to give it an excuse to act up.
        Thanks!

          If you have a service contract, you can probably push to have the engineer come out. It sounds like you'd have good reason to justify it. Good luck!

            Slightly off topic but.....
            I have just done the tubing replacement on the Junior and it went very smoothly, if a little bit fiddly.

            I had an engineer out last week for a separate issue and he seemed to think that the Preventative Maintenance Kit (spare tubing and replacement air filter) should be free if you have a service contract for your machine (which I do).

            Has anybody with a contract been getting this kit free or are we all paying for it?

              We already replace the pump tubing/filters once. I was only irritated, that there are four (?) tubings in the kit, but you only have to replace the upper two ones. Just try it! Like GraemeFox said, it's a little bit fiddly and we need two attempts but then the penny has dropped and we thought the video makes it far to complicated.

                We had to pay for it but after I complained about the exorbitant price (795 Euro for four tubings and five filters!!) I got one kit for free...

                  We've changed ours 3x since our upgrade at the beginning of 2012. Make sure you adequately tighten the connectors installing the new pump tubing - we were about 5 runs in after our last tubing change and had a couple of poor runs that presented as fluidics issues. The connectors had come loose and reagents were leaking. Our engineer recommends checking and re-tightening these before each run as the action of the pump can cause them to loosen over time.

                    Thanks all for your responses.
                    We definitely don't get these for free - in fact we just were informed that we hadn't received everything required for the kits we had purchased. The Wash buffer and sipper tubes and pre-wash tubes were sent after the fact.
                    I'll let you know if I have any hiccups.

                      Mine are free as a part of the super expensive service contract.

                        Genetic Variation in Immunogenetics and Antibody Diversity
                        by seqadmin



                        The field of immunogenetics explores how genetic variations influence immune responses and susceptibility to disease. In a recent SEQanswers webinar, Oscar Rodriguez, Ph.D., Postdoctoral Researcher at the University of Louisville, and Ruben Martínez Barricarte, Ph.D., Assistant Professor of Medicine at Vanderbilt University, shared recent advancements in immunogenetics. This article discusses their research on genetic variation in antibody loci, antibody production processes,...

                        Choosing Between NGS and qPCR
                        by seqadmin



                        Next-generation sequencing (NGS) and quantitative polymerase chain reaction (qPCR) are essential techniques for investigating the genome, transcriptome, and epigenome. In many cases, choosing the appropriate technique is straightforward, but in others, it can be more challenging to determine the most effective option. A simple distinction is that smaller, more focused projects are typically better suited for qPCR, while larger, more complex datasets benefit from NGS. However,...
