Today, we plated the transformations that we did yesterday. We are also expecting sequences for amiRNA that we ordered yesterday. | |||

'''Plating Transformations''' | |||
One plate of each allergen S and A and the introns PAL and PME. All but BetS and PME had colonies | |||
'''Sequencing Results for amiRNA''' | |||
Not one matched the sequences that we wanted. The customization sequences that we wanted (our miRNA sequence+ a little bit of RS300) were not present in all of the LTP and Bet sequences sent in. Even the Biobrick ends were not present in the sequences except for GFP, from our earlier sequencing order. | |||
What could have gone wrong? We suspect that the RS300 vector that was given to use already contains an interference sequence. The sequence that we used to design our primers are based on an RS300 vector without any inserted interference sequence. Christina has already sent an email to the lab that gave us the RS300 asking if the RS300 contains any interference, possibly GFP. That would explain our results. | |||
It is possible that we will have to go back and redo PCR ~ transformation. These results are all still from the first time that we tried making amiRNA parts, just different colonies. | |||

"c1" and "c2" are the customization (mutagenesis) sites corresponding to the capitalized portions of the primers suggested by the WMD3 tool. | |||
"c1" corresponds to the capitalized region of what WMD3 calls primer3 and to the reverse compliment of the capitalized region of primer4. | |||
Similarly, "c2" corresponds to the capitalized region of primer1 and the reverse complement of the capitalized region of primer2. | |||
For instance, WMD3 gives us the following when asked to design primers for the BET sequence: | |||
primer1: gaTTGGTTATATATATCGCACCTtctctcttttgtattcc | |||
