2. click on UPLOAD DATA from the 'x-files page'
3. add data etc.... and click submit: This generates a webpage and the URL to it is linked in the page you are directed to after you press submit. Copy that URL and past it into the wiki or into the web-browser url box to see what it looks like.
\* If you find that the picture you are uploading is not showing up e-mail Tejas.

Alternatively, you can also just upload files directly to the iGEM wiki. Either way is fine.

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

 Date: Oct 19, 2008
 Status report by: Tejas
 Part no.: BBa_K110017 -> BBa_K110023
 Part Description: yESapphire , mCherry, venusYFP, and Citrine 

 Work on YFP has progressed, though the biobrick system is giving diffiulty in obtaining a useful
 construct. Moreover, the YFP sequence may not fully match the expected sequence. However,
 fluoroescent proteins (yeast optimized) sent us as STABS from MIT are showing promise, and may be
 ready for some use by the Jamboree date if all goes well. Work will continue on venusYFP and
 mCherry (though mCherry unfortunately contains a restriction site). Sapphire must be started over
 sue to technical difficulties getting a clone.

GROUP 2: MATa Specific-promoters

Summary for MATa Specific Promoters Group

 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:
 http://partsregistry.org/cgi/partsdb/pgroup.cgi?pgroup=iGEM2008&group=Johns_Hopkins

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

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

 Summary: As of September 23rd, 2008
 We had successfully cloned BBa_K110005 and BBa_K110006 (alpha Promoters) and 
 BBa_K110003 (Long Terminator) into pGEM-T and Kanamycin biobrick vectors.  
 They await assembly and ligation.

GROUP 5: MATa Specific Promoters II

Summary for MATa Specific Promoters II Group

 Date: August 12, 2008
 Status report by: Richard Group
 Part no.: BBa_K110009
 Part Description: Ste2
 Summary here: We hit a dead end when we ran out of the miniprep DNA. We are going to have to start
 again from scratch        I suppose.
 Part no.: BBa_K110015
 Part Description: Mfa1
 Summary here: Same place as on Ste2.

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).
