GROUP 5: MATa Specific Promoters II

Summary for MATa Specific Promoters II Group

 Part Description: Ste2 Promoter Reverse
 Summary here: We were able to grow colonies with sequence verified Ste2 promoters. 
   The promoter is currently located in a glycerol stock in pGEM vector. One attempt to 
   transfer to the iGEM vector has been made, unsuccessfully. This was due to a mistake 
   in protocol however, so final transfer to the iGEM vector should still be straightforward. 
   Progress on this bio-brick has been paused in order to focus on MFA1, which is more 
   applicable to our project design because this Ste2 designed for the wrong direction.
 
 Part no.: BBa_K110015
 Part Description: MFA1 Promoter Forward
 Summary here: We have been unable to get successful, sequence verified clones with 
   our MFA1 promoter thus far. We currently have a few samples of DNA ready to be tested 
   by restriction enzyme digest, and then, hopefully, sequencing.

 Up to today...
 Since then -- we have been troubleshooting and working on getting higher concentrations and using
 the correct stock plates. Several delays have occurred,and we should be close to ligating into the
 iGEM vector from the pGEM vector for Ste2 promoter. Glycerol stocks of the Ste2 are currently available.   
 Verification of clones of the MFA1 promoter are still in progress.
 
 Status Report by: Alexandra McMillan

 8/24 
 Restriction Enzyme Digested and the insert appears promising. Ready for sequence submission for Ste 2 promotor.  

 

 8/21 
 Due to low concentrations, we needed to concentrate our DNA before preceeding. 
 Ethanol precipitation using EtOH/NaAc and 100 ul of miniprep mix was complete of the BBa_K110015 
 and BBa_K11009 minipreps.

 8/18
 Miniprep products were < 100 ng/ul. Restriction digest. There appear to be correct
 size inserts. Gel image coming. Results look promising.

 8/15
 DNA miniprep of BBa_K110015 and BBa_K11009 cultures

 8/13
 Incubated inoculations of old colony plates for approximately 12 hours. 

 By 7/19/08
 We successfuly transformed both BB 15 and 9 and ran a gel that came out with faint bands. 
 We digested BB 9 and 15.
