Biobrick tutorial Note: 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.

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
