In preparation for the 2008 iGEM competition, selected DNA 'bioparts' found in the Registry are transferred onto sheets of thesis paper using the pin tool replicator in order to be mailed to teams at participating colleges and universities. Since this is the first year that iGEM will be using the thesis paper in place of welled plates to distribute the 'bioparts', the pin tool replicator method of transfer was evaluated for possible DNA and culture cross contamination.
Cross Contamination Among DNA Samples from the Same Source Plate
Materials:
- 96 deep well plate
- 25% Cresol Red solution
- 96 Multi-Blot (Pin Tool) Replicator
- source plate Library Copier
- Thesis Paper with iGEM 96-block grid print
- Lint-free blotting paper
- VP 110 Pin Cleaning Solution
- 99% Isopropynol
1. Add 1.0 ml of 25% Cresol Red solution to the wells of every other column on the deep well plate.
2. Transfer the 25% Cresol Red solution to the thesis paper grid using the Pin Tool Replicator.
3. Clean the pin tool replicator.
4. Observe spotting on thesis paper grid to determine cross contamination among grid spaces.
Culture Cross Contamination Among Samples from the Same Source Plate
Materials:
- 96 deep well plate (2)
- 96 Multi-Blot (Pin Tool) Replicator
- LB with Ampicillin broth
- Red Florescence Protein (RFP) cells
- Library Copier (2)
- Lint-free blotting paper
- VP 110 Pin Cleaning Solution
- 99% Isopropynol
1. Add 500. ul of LB broth to each well in a 96-deep well source plate.
2. To every other column of wells add 10. ul of suspended RFP cells, leaving the alternate columns with only LB broth.
3. Using the Pin Tool Replicator, Transfer the culture from the source plate to a transfer 96 deep well plate of LB broth.
