| - | You should make use of the calendar feature on the wiki and start a lab notebook. This may be looked at by the judges to see how your work progressed throughout the summer. It is a very useful organizational tool as well.

| - | Read absorbances for all four solutions that contain plasmids with our cassettes: Ura3, Leu3, KanMX4, and NatMX4.
| + | |
| - | | + | |
| - | Data was obtained using a nano-drop spectrophotometer. Absorbance was observed between 250nm and 280nm.
| + | |
| - | | + | |
| - | DNA Concentrations were as follows:
| + | |
| - | *Ura3: Very high absorbance reading, must be diluted 1/10 in order to get accurate concentration reading.
| + | |
| - | *Leu2: Very high absorbance reading, must be diluted 1/10 in order to get accurate concentration reading.
| + | |
| - | *KanMX4: 30.5 ng/uL
| + | |
| - | *NatMX4: Very low absorbance reading, eluent was discarded.
| + | |
| - | *Last year's NatMX4 solution: Very high absorbance reading, must be diluted 1/10 in order to get accurate concentration reading.
| + | |
| | | | |
| - | Next step: Make diluted stock solutions of the Ura3 and Leu2 plasmids and take new absorbance readings.
| + | [[Team:WashU/Notebook/May2011|Lab Notebook-May]] |
| | | | |
| - | For NatMX4, we will begin a new culture with a new colony and redo the mini-prep. If unsuccessful, we will use last year's stock.
| + | [[Team:WashU/Notebook/June2011|Lab Notebook-June]] |
| | | | |
