| '''Ligation'''
| |
| *Since our e-gel failed, we ligated DNA extract from David and Peng.
| |
| *Mixed 6 µL insert (E0241), 2 µL vector (R0010), 2 µL DNA dilution buffer in reaction vial
| |
| *Added 10 µL ligation buffer
| |
| *Added 1 µL ligase, mixed
| |
| *Let incubate 5min at room temperature
| |
|
| |
| '''Transformation'''
| |
| *Mixed 20 µL of ligation product with 30 µL competent cells
| |
| *Negative control: 2 µL of dH20 with 30 µL competent cells
| |
| *Positive control: 5 µL of positive control with 30 µL competent cells
| |
| *Incubate on ice for 20min
| |
| *Heat shock @42C for 30s
| |
| *Rest on ice for 2min
| |
| *Incubate overnight @37C

| '''Biobrick tutorial'''
| |
|
| |
| ''More detailed procedure notes are in lab notebook.''
| |
|
| |
| *Began with 12 samples (3x each of negative control, R0010, E0241, E7104). Fortunately our negative controls showed no growth overnight.
| |
|
| |
| *Made 9 minipreps for the remaining samples. Set aside the E7104 samples (they are a positive control).
| |
|
| |
| *Performed digests on 2x each of R0010 and E0241. We lost one of our E0241 samples by accident, so we threw out an R0010 sample to balance.
| |
|
| |
| *Added Calf Intestinal Phosphatase (CIP) to R0010 samples to prevent self-ligation of the R0010 vector.
| |
|
| |
| *Performed gel electrophoresis on R0010 and E0241 samples.
| |
| **Our e-gel was not entirely successful.

| Must be more careful next time.

| '''Notes on using the nanodrop'''
| |
| *Nanodrop measures concentration of DNA in small samples (1 µL). It is apparently not very accurate.
| |
| *Clean nanodrop thoroughly with kimwipes and ethanol, before and after each use
| |
| *On desktop, "ND-1000"->"Nucleic Acid"
| |
| *Before each set of samples:
| |
| **Calibrate nanodrop with drop of distilled water
| |
| **Calibrate nanodrop with drop of background (solute), e.g. distilled water or elution buffer
| |
| *Add sample to nanodrop, enter name of sample, "Measure"
| |
| **Note: mix sample before placing on nanodrop
