You know you’re a biology nerd when…


…you think the PCR song is kind of catchy.

The PCR Song

There was a time when to amplify DNA,
You had to grow tons and tons of tiny cells.

Then along came a guy named Dr. Kary Mullis,
Said you can amplify in vitro just as well.

Just mix your template with a buffer and some primers,
Nucleotides and polymerases, too.

Denaturing, annealing, and extending.
Well it’s amazing what heating and cooling and heating will do.

PCR, when you need to detect mutations.
PCR, when you need to recombine.
PCR, when you need to find out who the daddy is.
PCR, when you need to solve a crime.

(repeat chorus)

    I learned how to do the “manual” version as an undergrad (took half a lab and many days at best).

    soon after I received my grad degree (about 5 years later), i got a chance to try a machine where you could just insert a sample, press a fucking button, and 4 hours later, you were done. the machine plugged into the wall and was about the size of a microwave oven.

    amazing.

    It gave me chills. Or maybe the flu.

    Chemists need one. Sonogashira Shuffle, maybe, or the Diels-Alder Stomp.

    I only watched it the one time, and it is still kind of echoing in my head…damn you, bio-rad. Damn you all to…wait, I don’t believe in any of that stuff. Cool tune, y’all.

    I’m doing a PCR right now… and I think I’m going to blast this song out into the lab. It certainly adds a little magic to the process of “insert a sample, press a fucking button, and 4 hours later, you were done.”

    PCR.

    Three little letters that represent for me the whole gamut of emotions from joy to bewilderment to complete & utter unmitigated despair!

    A true love/hate relationship.

    don’t get me wrong, I wasn’t being sarcastic; it was damn near magic to me, having been involved in doing it “the old way”.

    but then, I don’t recall having to sit around while the new PCR machine was processing.

    I was helping out with a project looking at genetic diversity within populations of salmonids, so I also had the sense of how important the results were, which made it a bit less tedious, somehow.

    just think about how many times you’d have to repeat that song if you were doing the “old way”

    ;)

    Didn’t Kary Mullis support the ‘AIDS-dissendent’ kooks for a time? I recall an introduction to a certain Duesberg book. Seperately, I recall him insisting global warming and the ozone hole were not caused by humans, as recently as the late 1990s.

  7. Dave Eaton says

    Why do people keep mentioning Mullis’ goofiness about HIV? It didn’t make him uninvent PCR, which is what the song reference is about. This is a disturbing religious tendency- shunning and purging all references to heretics- that I’d just as soon not see us pick up.

    Maybe the song could contain a single note played on a triangle as his name is mentioned- sort of a musical asterisk- with reference to his views on HIV not being endorsed by Bio-Rad being included in the sheet music.

    WOW. “Awesome” doesn’t begin to describe this.

    Who’s the gravelly-voiced dude supposed to evoke? Springsteen? Will I have to watch “We Are The World” on utoob to figure it out? OH NOES!

    As I posted at the site where I first saw this.Even though it isn’t his area of expertise I can’t help but feel that Tom Lehrer would have done it better.

    @ Ichthyic:

    I wasn’t knocking your comment. I do PCR’s everyday, and they certainly don’t seem very magical, though I do find myself holding my breath every time the UV light flickers on in the Gel Doc… oh please, please let there be bands!

    It certainly is nice to be able to set up the reaction and then work on something else for about 2.5 hours (or take a long lunch). I couldn’t imagine doing PCR in the pre-Taq days.

  11. Ichthyic says

    4 hours? Bands? Better drag yourself into the 21st century gentlepeople.

    come to think of it, that was indeed back around 1996/7.

    if 5 years was all that was needed to get microwave sized PCR processors that do it in 4 hours, I’m sure that’s ancient tech 10 years later.

    so what does it look like these days? smaller than a toaster and takes 5 mins?

    well, i guess there has to be some size limit due to the needed chemicals at least.

    ah yes, i see they indeed have shrunk quite a bit:

    Whenever any of us were feeling gripey about how horrible our equipment was running, my last PI would tell us how he used to MHC type mice by doing rejection screens in mice.

    I know PCR isn’t perfect (he says, having banged his head all day trying to cut down his number of labeled primers to something under 32), but holy crap it’s much better than not having it at all.

  13. Mollie says

    We listened to this song multiple times in the lab today. It was a good antidote to a drizzly Friday in Boston.

  14. Shigella says

    Awesome. The dude planting an affectionate kiss on the PCR machine before throwing his head back and belting out with all his soul was a nice touch.

    PCR: Rocks my face.

    HPLC: Can burn in hell. Forever. I so mean it. Dumbass machines break/leak all the freaking time and all the thousands of parts are $500 a pop. Not that I’m bitter toward HPLC. Not at all. No bad experiences here. Move along now.

    Back when I was a young PhD student, one of the other groups in the lab had a PCR machine (this was so long ago biologists would show off by being interviewed on TV in front of three of them). It was a strange beast, partly because the PCR didn’t work during the summer. Eventually, it became so tempramental that “Perkin-Elmer” became a swear word.

    I’m not even a scientist, and that brought a tear to my eye. It was beautiful. Who says scientists have no soul?

    Some surprisingly nice voices too.

  17. Jan Chan says

    Is this an official qualification for being a biology nerd? I already played it over and over again more than a dozen times, and sent it to my friends.

    Yeah. Few things can be as empty as a gel with PCR results can be.

    and all the thousands of parts are $500 a pop.

    After all, it isn’t called High-Price Liquid Chromatography for nothing.

    Thanks for posting this! I laughed do hard I cried, and thanks to Bio-Rad for having a sense of humor.
    I gave a lecture to high school kids a few weeks ago about PCR and I wish I had known about this song.

  21. Veroniqué says

    I don’t care that it is an ad either. Absolutely gorgeous and with a beautiful sense of humour.

    A delightfully crafted song (and lyrics, hahaha). “Catchy” is correct. Thank you for posting this. Made my day!!
