Sequencing Parts

Stephanie Nanodropped and sent the following parts for sequencing:

Constructing Growth Curves

Stephanie used the plate reader and Bl21+I13263 cells diluted 1:10, 1:20, 1:30, 1:40, 1:50, 1:60, 1:70, 1:80, 1:90, and 1:100 as well as to construct a growth curve of OD vs time.

Liquid Cultures

Stephanie grew liquid cultures of I5311, OmpA1+his, I13522, T9002, and I13263 in preparation for induction on 07/03/07.

Perry performed the following digests:

Perry and Stephanie also ran a gel and gel-extracted the result. However, the J37034 did not turn out as expected so Stephanie ran another digest on the J37034

Results of the Growth Curves

Results posted by Stephanie


Perry and Stephanie digested the E0240, S03608, S03623, and B0015 parts in order to rebuild the J37034.

Ligation and Transformation of Parts

Perry and Stephanie ligated with Quick Ligase: 7ul S03608/S03623 + 3ul B0015 in pSB1AK3. They then transformed the ligated parts into 20ul Top10.

Perry's notebook entry

Plate Reader Fluorescence Setup

Stephanie set up a plate reader experiment for fluorescence.

"First, I loaded the machine with cells (dilution - 1:10 ... maybe will dilute in greater amounts next time, eg 1:100?) and watched OD. Around 0.3OD I took them out, transferred to a clear/black 96-well plate (next time, will start with one of these), and induced cells with OHHL."

Stephanie's notebook entry


Stephanie transferred plates of the ligations from the incubator to the fridge. She also checked the results from the plate reader fluorescent readings.

Colony PCR

Stephanie prepared a colony PCR of several colonies of S03608-B0015 and S03623-B0015

Stephanie's notebook entry

The results were not good.

Colony PCR of F2620

Stephanie and Perry prepared and ran a colony PCR of F2620

Digestion, Ligations, and Transformations, Oh my!

Stephanie and Perry digested and ligated the following parts:

where X>Y indicates that the piece X was ligated into the larger piece Y, containing the vector.

Stephanie and Perry also transformed all the above parts into Top10 cells. In addition, they transformed the following parts into Top10 cells:
