Construction Technology

Conclusion: It is possible to construct any piece of DNA.

Characteristics as of 1 February 2006:

  • Cost. ~$1 per bp
  • Length. ~100 bp direct chemical synthesis, ~15,000 bp PCR assembly, ~3,500,000 bp inchworm elongation
  • Error Rate. From 1:10 to effectively zero
  • Time. 6 hours for 100 bp, 2-6 weeks for 15,000 bp, ~2 months for 50,000 bp, ~7 years for 3,500,000 bp
  • Diversity. From one molecule to millions of molecules (heavily dependent on method)
  • Terms of Sale. Varied (from no-strings-attached to full-rights-reserved).

MTA examples

Example 1

From: hkeller@MIT.EDU
Subject: Re: Fwd: Re: Strain request
Date: January 31, 2006 2:41:31 PM EST

I just spoke with <person> about getting copies of the entire <deleted> series. I explicitly told her I work for you (she asked in what capacity). She did ask why we wanted them and I told her to test them out with some of our constructs to see how useful they are. She is going to send me a sample MTA agreement (via e-mail) by the end of the week. She warned me of the following:

1) They require signature of an MTA before release of the strains (which we knew already).
2) We must provide them with a detailed experimental plan specifying how we plan to use the strains.
3) The strains cannot leave our lab.
4) They request that we share any results that we obtain using the strain(s).
5) No changes can be made to the chromosome of any of the strains.
6) There is a small transfer fee associated with obtaining the strains (she said she would have to speak with <person> to determine what the exact amount is).
I'll forward the MTA on when I receive it. Do you still want to proceed with this, knowing the above?

Subject: MTA for Tet system

Hi Drew - Are you ok with me asking the fellow in Germany who developed the [reverse] Tet system that the van Oudenaarden lab is using for an MTA ?
thanks, Alex.

And so on...

Dear Dr. Endy,
My name is <grad student at UCLA>. I am a graduate student in <some lab> at UCLA. I am attempting to construct a gene circuit using the tetR repressor for a metabolic engineering project and I was wondering if it would be possible to obtain your plasmid pSB1A2 containing part BBa_C0040 (a degradable form of the tetR repressor) from the BioBricks project. Thank you for your assistance.
Sincerely, <graduate student at UCLA>

Hi <student>,
Just a follow-up to your email. Hopefully Meagan has been in touch with you already (below).  But, FYI, request received and should be arriving shortly / arrived.

Dr. Endy-
Thank you for your assistance. The part was received late last week.
