DNA Manufacturing Enters the Age of Mass Production (ieee.org) 82

Posted by samzenpus from the making-life-better dept.
the_newsbeagle writes: Now that it's easy and cheap to build strands of DNA, what kinds of strange new organisms will scientists and start-ups build? That's the question raised as synthetic biology companies like Twist Bioscience and Zymergen start up their DNA manufacturing lines. Researchers who order DNA snippets typically pay on a cost-per-nucleobase basis. These companies say their mass-production techniques could bring prices down to 2 cents per base, which would allow researchers to scale up experiments and learn through trial and error.

      In all honesty, I think that this technology has some promise when it comes to recreating penises that have been destroyed for one reason or another.

      I'm sure we all know the golfer who had an accident, and as a result of a club impacting him in the groin his penis was completely destroyed. Or we know the skier who skied crotch-first into a tree and had his scrotum and penis turned to mush.

  • This doesn't cover the things I would want to know--such as what they expect the computer's error rate (think 'mutation' here) because if my cost-per-base is low but I have to order a lot more copies simply to be certain I get the correct sequence, I'm not so sure it's a good idea. Having actually done this as an undergrad, the part that I'd stress out about most is the whole process of checking it--getting the gene into the vector and the vector into the host can be annoyingly finicky.

    • As mentioned in the article the DNA manufacturing makes cheaper only the first part of the process and the main cost remain the same, the advance will most likely save time but not money. For example instead of running a few reaction with the 8 to 10 oligos you felt you could order that week you just make a 96 well plate of reactions each with a different one and check how many give a successful transformation. Of course if that is above your lab capacity then the advantages are not so good.

        I did read the article, and the thing is that it won't necessarily save time or money if the error rate is higher--with what you're suggesting, if I'm going to be optimistic I might get maybe a fifth of those wells actually being a successful transformation, assuming that my host isn't one where using a 96 well plate actually will lower my success rate.

          Its not important to increase the error rate if the main product you are wasting is cheap DNA sequences. Lets say that you now can try 5 or 6 of them in one week, then another 5 or 6 the next week until you are successful (so you can save on DNA by ordering only the absolutely minimum amount). If you can get the oligos dirt cheap then you just order a butt load of them and try as many as you can, get this first step results much faster without so much waste. It will not matter if you get only one good trans

            Wait, what? Nobody wants to increase the error rate here, the point is that if the cost of the lower price is a significantly higher rate of errors, then you'll end up wasting everything else involved in getting to the point where you can check to see if you did get the correct gene in. This is only really going to save time and/or money if its accuracy is sufficiently close to being as good as the previous methods that you come out ahead in the end.

              There is no real reason why quality has to drop, but even if that is the case there are quite a lot of methods for screening cheaply for desired results when you get more than you can manage (specific methods of course depending on what you are trying to do), If you already get enough samples to have to wait later then of course there is no value on getting more of them with a supposedly lower quality, but if your bottleneck is the first step then of course manufactured DNA is going to help getting the job

        • Your experience may still hold true for small labs, but many research campuses have sequencing cores now with fast turn-around. I give them the tube with DNA and primers, and they email me the sequence data the next day (rarely, it'll take them two days). I hear there's a company in NYC that promises 12-hour turnaround for samples they get in the city. Now, smaller institutions may take more time, but sequencing has been advancing pretty quickly as of late.

            I was actually at one of the major research campuses--so they've probably gotten this in, and I've a pretty good guess how the fast turnaround is managed. When I last checked it was in the "whenever we get the bugs worked out" phase of development. It still would be a bit of an annoyance for me, but that's because I loved the parts involved in getting to doing the sequencing, not processing the sequencing data...which is more or less why I gave up being a biochemist when my body decided to no longer react

            • If it was a major research campus, I'm sure they have it by now. I kind of hate doing mini-preps, but for some reason I don't mind doing giga-preps. And yeah, sequencing data can be annoying to get through, depending on what you're trying to do (and how good your map is...). That's really unfortunate about the gloves. I don't know what I'd do if that happened to me!

I think it's a great idea, personally, but at least in the US there are far too many people who either oppose GMOs with a near-religious fervor, or oppose reducing their environmental impact with similar fervor, for this to be successful commercially in a domestic market.

  • I've bought DNA snippets for use in experiments for years (DNA is about $0.50/base from existing companies). The cost of DNA has been trivial for scientific work for a long time. The real cost is in the labor and equipment that goes into running an experiment. On a million dollar a year project, reducing the cost of DNA from $1000 a year to $10 a year doesn't really change the pace of research. That's not enough savings to hire another person to get more work done, or buy any of the equipment necessary.

    • For big projects, you're right, this won't do that much (although $990 is enough to buy a nice repeating pipettor...). However, it does lower the bar for smaller projects, especially those with cheaper initial labor costs (projects for undergrads to play around with, for example). It's not a game-changer, but it'll probably be useful in some scenarios.
