-
   Summary here.
+
   The yeast vector pRS414 will be temporarily used until it can be adjusted to meet registry
-
 
+
  standards. pRS414 contains one EcoRI site and one PstI site, both directly adjacent to each
 +
  other. This may make digest a little less efficient. Procedure involves first digesting with
 +
  Pst1 for one hour, then digesting with EcoRI overnight (sequentially, not simultaneously), as
 +
  EcoRI can tolerate low overhangs better than PstI, according to the NEB catalog. The following
 +
  is a gel run on an E/P simultaneous digest of pRS414.
 +
  Lane one is log 2 ladder. Lane 2 is uncut pRS414 (supercoiled so runs fater). Lane 3 is cut
 +
  vector. It may have only one cut, with half at EcoRI and half at PstI, depending on efficiency of
 +
  the second cut occuring after the first.<br>

 +
  October 31st- Successful transformants from either set of ligations (of Promoter + Fluorescent

Status Reports

The status reports of each group below were continuously updated as we worked on the biobricks.
Click on the name of each group to find past status reports throughout the sex detector project.

To learn more about each biobrick, please refer to the Biobrick page.


GROUP 1: Fluorescent Proteins

Summary for Fluorescent Proteins Group 

 Venus YFP (BBa_K110021) was able to be constructed and sequence verified(with one possible
 mutation), however due to being unable to RE digest the insert out of the biobrick
 vector, possibly due to contamination,  the part was not sumbittied to the registry... yet.
 We will submit it after it is verified, after the competition.

 We were able to produce sequence-verified clones of BBa_K110008 and BBa_K110016:
 http://partsregistry.org/cgi/partsdb/pgroup.cgi?pgroup=iGEM2008&group=Johns_Hopkins .

GROUP 3: Short Two-Way Stops 

 We were able to produce a truncated two-way terminator (thus a one way) 
 from the STE2 gene - BBa_K110012. Please see Link for information:

GROUP 4: Long Two-Way Stops & MAT(alpha) Specific Promoters

Summary for Long Two-Way Stops & MAT(alpha) Specific Promoters Group 

 We were able to produce BBa_K110005 and BBa_K110006 (alpha Promoters) in iGEM vectors.
 Also BBa_K110003 was able to be produced and sequence verified. Check out these parts here

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.

GROUP 6: Vectors

Summary for Vectors Group 

 Date: July 31, 2008
 Status report by: Tejas
 Part no.: BBa_K1100XX -> BBa_K1100YY
 Part Description: Vectors for concatenating and executing BioBricks
 
 The vectors to be used were delivered to us in STABS from MIT. They are pSB4A5 (amp), pSB4C5
 (cam), pSB3K5 (kan), and pSB4K5 (kan). The vectors come pre-inserted with the ccdB gene,
 preventing growth in all E. coli strains except DB3.1. Total amount of DNA extracted from mini
 -prep is estimated between 5 to 20 ug per vector. Restriction digests confirmed the extracted
 DNA was vectors.([http://www.jhu.edu/iGEM/Group6:Vectors/2008-7-24.Vectors%20(CAM,AMP,KAN3,KAN4)%20after%20Digest.Tejas.html Digestion of all four vectors]).
 Vectors were transformed into JM109, BB#2198 (DB3.1), and BB#5777 (DB3.1). All gave expected
 results. 1 ug of each vector was digested for future use. Gel of digestion shows DNA is correct.

GROUP 7: Microscopy/Yeast

Summary for Microscopy/Yeast Group 

 Date: Oct 27, 2008
 Status report by: Tejas
 Part no.: no Biobrick part
 Part Description: Yeast vector pRS414 to be temporarily used.
 
 The yeast vector pRS414 will be temporarily used until it can be adjusted to meet registry 
 standards. pRS414 contains one EcoRI site and one PstI site, both directly adjacent to each 
 other. This may make digest a little less efficient. Procedure involves first digesting with 
 Pst1 for one hour, then digesting with EcoRI overnight (sequentially, not simultaneously), as 
 EcoRI can tolerate low overhangs better than PstI, according to the NEB catalog. The following 
 is a gel run on an E/P simultaneous digest of pRS414.
 Lane one is log 2 ladder. Lane 2 is uncut pRS414 (supercoiled so runs fater). Lane 3 is cut 
 vector. It may have only one cut, with half at EcoRI and half at PstI, depending on efficiency of 
 the second cut occuring after the first.

GROUP 8: Assembly Progress

Summary of Biobrick Assemblies: 

 Planned Schedule for Further Work:

 October 31st- Successful transformants from either set of ligations (of Promoter + Fluorescent 
 Protein) and transformations will be grown up for Miniprep. 

 November 1st- These pieces will be miniprepped and digested.  Digested fragments will be ligated 
 together with the terminator in the middle, into a pRS414 yeast/bacterial shuttle vector.  
 Non-digested fragments of a promoter + fluorescent protein will also individually be transformed 
 into yeast, with hopes that they will fluoresce.

 November 3rd- Full construct insert will be transformed into yeast, pending identity verification.

 November 6th- Pretty Yeast! (Hopefully).
