iGEM 2014 Measurement Interlab Study

Introduction

All iGEM teams are invited and encouraged to participate in the first international interlab measurement study in synthetic biology. We’re hoping this study will get you excited for iGEM and help prepare you for the summer!

Please note: All Measurement Track teams are required to participate in the interlab study.

The goal of the interlab study is to obtain fluorescence data for three specific genetic devices expressing GFP from iGEM teams around the world. Can you measure fluorescence somewhere in your lab? Then this is the perfect study for you! Even if your lab or the organisms you work with mean that you can’t measure GFP from the specific devices, we want every team to be able to participate: email measurement at igem dot org and we will work out an alternative.

All teams who participate in the interlab study will be acknowledged at the Giant Jamboree with a special Measurement Prize!

For any questions, contact measurement at igem dot org.

Registration and Timeline

Teams intending to participate in the Interlab study should sign up by emailing measurement at igem dot org.

Schedule:

  • Sign-up Deadline: July 1st, 2014
  • Data Due: September 19th, 2014
  • Results Announced, Prizes Awarded: At Giant Jamboree!

Interlab Study Requirements

  1. Each participating team must have an “Interlab Study” page on their wiki for easy reference for the Measurement Judges.
    1. All devices measured for this study should be listed on this page
    2. All protocols followed for this study should be linked/posted on this page
    3. Sequencing data for all measured devices should be posted on this page
      1. Note: A restriction map (a restriction digest run on a gel) confirming the correct size of the device will suffice if DNA sequencing is not possible
  1. Each team must use the three BioBrick devices listed below in the “Required Devices” section.
    1. Note: Teams are encouraged to measure more devices (see “Extra Credit” section below), but the three required devices must be included for the Interlab Study (unless an alternative set is required and negotiated via email to measurement at igem dot org .
  1. Each participating team must collect and submit fluorescence data for these three devices (the data will be submitted through the “Interlab Study” form, see step 4).
    1. This data may be obtained by any means possible for the teams. Any instrument capable of measuring GFP is acceptable!
    2. Measurement data should be submitted in absolute units if possible. There are many ways this can be done, depending on your lab. If your lab cannot measure absolute units, relative units are acceptable.
      1. Hint: if you have access to a flow cytometer, absolute units can be measured by calibrating against standard fluorescent beads. A method for doing so is described (and supported with online tools) at: TASBE Tools.
    1. Data must be measured in triplicate (i.e., three samples for each device).
      1. Note: The mean and standard deviation across the replicates must be included.
      2. All teams must fill in the “Interlab Study” form where they will indicate the equipment used to measure the cells, describe how the data was collected, and list all controls used.

Required Devices

The three specific devices teams are required to measure fluorescence data for are given below.

Important notes: The first device is already built and available in the distribution kit. The second and third devices must be built using the BioBricks standard protocol by the teams participating in this study.

  1. Existing device: BBa_I20206 (J23101-B0032-E0040-B0015) in the pSB3K3 vector.
    1. Kit location
      1. Plate 4, Well 18A
  1. New device to be built by the iGEM team: BBa_J23101 + BBa_E0240 (B0032-E0040-B0015), must be built in the pSB1C3 backbone
    1. Kit locations
      1. BBa_J23101 (called BBa_K823005 when in pSB1C3): Plate 1, Well 20K
      2. BBa_E0240 (in pSB1C3): Plate 2, Well 24B
  1. New device to be built by the iGEM team: BBa_J23115 + BBa_E0240 (B0032-E0040-B0015), must be built in the pSB1C3 backbone
    1. Kit locations
      1. BBa_J23115 (called BBa_K823012 when in pSB1C3): Plate 1, Well 22I
      2. BBa_E0240 (in pSB1C3): Plate 2, Well 24B

Extra Credit Opportunity for the Interlab Study

Have you finished your Interlab Study requirements above? Still eager for some more measurement fun? Then these “extra credit” assignments are right for you!

For teams looking to do some measurement work beyond the interlab study requirements, we are offering three chances for “extra credit”. You can complete any or all of these extra credit assignments if you complete the Interlab Study.

Teams who go above and beyond the interlab study will be acknowledged for each “extra credit” assignment completed at the Giant Jamboree with a special Measurement Prize! Each assignment is weighed equally.

Please note: Your team must complete the Interlab Study requirements listed above in order to earn any “extra credit”!

  1. Measure cell-to-cell variation for the three required devices.
    1. Can you measure single cells? Or can you find a team that can help out? If so, then you can complete this “extra credit” assignment (and maybe squeeze in a collaboration between iGEM teams as well)!
  1. Build and test at least three devices that are identical to devices that you have measured, except that they express RFP rather than GFP. Compare the fluorescence for RFP devices to the fluorescence for GFP devices.
    1. Are you interested in seeing how regulatory and protein elements interact? Some interactions are very sensitive and others more robust. Can you find a pattern of interaction? Absolute fluorescent units can be very helpful here!
  1. Build E0240 devices with the entire Anderson library of constitutive promoters (J23100-J23119) following standard BioBrick protocols and submit measurements for GFP expression for all devices.
    1. Are you interested in seeing how minor changes in promoter sequences can impact gene expression? If so, then this “extra credit” assignment is right for you! (Note: Measure this set of parts the same way you measured the required devices.)

For any questions, contact measurement at igem dot org.

GOOD LUCK!
