+ | <h2>Tuesday</h2> | ||
+ | - Selected a single colony from each of the eleven plates and the colonies were grown in TY broth with Kanamycin O/N | ||

+ | - Set up the first 11 Dig-Lig experiments, placed into PCR block on the slow protocol. | ||
+ | - Carbenicillin plates made and spreadplated with 40 μl of XGAL and 100 μl of IPTG. Plates left to dry upside down in 37°C incubator. | ||
+ | |||
+ | - Transformation of GG DNA into electrocompetent E.coli cells, PROTOCOL: | ||
+ | • Cells removed from -80°C freezer and allowed to thaw. | ||
+ | • A 5 µl sample of DNA was added to a 50 µl aliquot of cells. | ||
+ | • Transfered each 55 µl sample into a cuvette. | ||
+ | • Electroporation pulse on setting ECR1. | ||
+ | • A 500 µl of SOC broth was added to the cuvette. | ||
+ | • A 555 µl cuvette sample was transferred to an eppendorf tube and incubated for 40 min at 37°C. | ||
+ | • A 100 µl sample was spreadplated onto agar plates containing carbenicillin and incubated O/N at 37°C. | ||
+ | |||
+ | - A 20 µl PCR reaction was set up using a GG level 1 acceptor as template DNA containing the primers P1: 0349(PRO+5U) and 0353 (3U+TER) and P2: 0350 (PRO+5U) and 0354 (3U+TER). | ||
+ | - A TBE buffer 1% agarose gel was poured for diagnostic purposes to check the amplification of the PCR products. | ||
+ | |||
+ | - PCR product purification | ||
+ | • Pre-percipitation to remove TAQ polymerase and protein was completed followed by phenolchloroform extraction (x2). Aqueous layer is removed and discarded leaving DNA. | ||
+ | • Precipitation to remove buffer was carried out by adding Na acetate (10%) and ethanol causing the DNA to come out of solution. Aspirator was used to remove buffer, salt and ethanol. | ||
+ | • A salt wash was completed to remove the acetate and ethanol. | ||
+ | • Sample was incubated at 65°C for 2 min to evaporate the ethanol. | ||
+ | <h2>Thursday</h2> | ||
