Another digestion/ligation filled day at the IGB for the RNA Decoder! Here is what went down:

The digestions were mixed by flicking the tube was quick spun to bring liquid to the bottom of the tube. They were incubated in a 37 C water bath for 15 minutes, and then incubated in an 80 C water bath for 20 minutes. Double the amount of PstI enzyme was used because in NEBuffer 4, PstI has a 50% efficiency compared to NEBuffer 2.

Ligations came next:

2.0 uL Digest 9 2.0 uL Digest 9 2.0 uL Digest 9 2.0 uL Digest 9

The tubes each ligation was made in was mixed by flicking and then quick spun down. The ligations were incubated at room temperature for 10 minutes, and then incubated in 80 C for 20 minutes.

Transformations were done next by mixing 50 uL of NEB dH5α competent cells and 3 uL of the ligation liquid to the tubes. I used flicking to mix the cells and ligation. Then this was transfered to a electrocuvette and electroporation was done. After 1 mL of SOC media was added in the electrocuvette and then put in the 37 C room to incubate for an hour. Then the cells were mixed back into the media by pipetting up and down and 200 uL of the transformants were plated one Chloramphenicol plates. Those were put into the 37 C room to overnight.
