| - | <partinfo>BBa_B0015</partinfo> was accidentally not inoculated yesterday... :(
| |
| - | Luckily, we had a DNA stock for this part stored at -20°C, so we used this stock for ligations.
| |
| - |
| |
| - | Cultures grown overnight at 37°C 220 rpm were all saturated. BioBricks were extracted with MiniPrep kit.
| |
| - | Surprisingly, after the first centrifugation, we observed that <partinfo>BBa_E2050</partinfo> pellet was orange!! This is curious, because this BioBrick expresses mOrange, but it lacks of promoters. Probably, this spurious transcription is due to the promoter of Kanamycin resistance, that is oriented in the same direction.

| |
| - | *Both I1-1 and I1-2 are positive. We choose I1-2, from now on named I1, for sequencing and gel-extraction because its DNA concentration is better.
| |
| - | *I2-1, from now on I2, is positive so it will be used for sequencing and gel-extraction.
| |
| - | *I3-2 is negative, while I3-1, from now on I3, is used for sequencing and gel-extraction.
