User:KCliff/Evaluating Cross Contamination Using The Pin Tool

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 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 actual plates to distribute the 'bioparts', the pin tool 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
              96 Multi-Blot Replicator (Pin Tool)
              source plate Library Copier
              Thesis Paper with iGEM 96-block grid

1. Add 1.0 ml of 25% Cresol Red solution to the wells of every other column on the deep well plate.

2. Inoculate the grid on the thesis paper with 25% Cresol Red using the pin tool.

3. Clean the pin tool.
