Status Reports
The status reports of each group below will continuously be updated as we work on the biobricks. The following PDFs contain progressive versions of our status reports as we continue through the sex detector project; they are added weekly. To learn more about each biobrick, please refer to the Biobrick page.
Status Report 2.1 - 07/12/08

GROUP 1: Fluorescent Proteins
Summary for Fluorescent Proteins Group
Date: July 22, 2008 Status report by: Tejas, Ingrid Part no.: BBa_K110017 -> BBa_K110023 Part Description: yESapphire , mCherry, venusYFP, and Citrine
Work on yESapphire was gratiously done by James. Primers were designed. Restriction site ends have been added through PCR. The product was cloned into JM109. Colonies were picked and an inoculation was grown. Miniprep was performed and subsequent DNA was CS PCR'd and run on a gel to verify contents. ([http://www.jhu.edu/iGEM/Group3:ShortTwo-wayStops/2008-7-22.Short%202Way%20Stop,%20Alpha%20Promoters,%20&%20Sapphire%20FP.Allison%20Suarez%20and%20Nate%20Sotuyo%20.html Short 2Way Stop, Alpha Promoters, & Sapphire FP]) BioBrick is currently being sequenced.
Work on mCherry and venusYFP (BBa_K110018 -> BBa_K110021) is currently being done. Primers were designed. Restriction sites have been added through PCR. ([http://www.jhu.edu/iGEM/Group1:FluorescentProteins/2008-7-23.PCR%20Products:%20mCherry%20and%20Venus%20YFP,%20both%20RtL%20and%20LtR.Ingrid,%20Tejas.html PCR Products: mCherry and Venus YFP, both RtL and LtR]) The products were cloned into JM109 and plated. 3 colonies per 4 BioBricks (total 12) were picked, grown out, mini prepped, and digested for verification on a gel.
According to the results, ([http://www.jhu.edu/iGEM/Group1:FluorescentProteins/2008-7-22.Venus%20YFP%20and%20mCherry%20Miniprep%20check%20via%20digest.Ingrid.html Venus YFP and mCherry Miniprep check via digest]) , only one of the mCherry's (BBa_K110019) is the correct product. A second Digest was preformed to check this, meanwhile new colonies have been picked on 7.22.2008 and are being grown out for a higher yield of DNA so that it can be sent off for sequencing. [http://www.jhu.edu/iGEM/Group1:FluorescentProteins/2008-7-23.Re-Digest%20of%20three%20samples%20of%20mCherry%20BBa_K110018.Ingrid%20.html Re-Digest of three samples of mCherry BBa_K110018]
Work on Citrine has not yet begun. Primers have been designed and ordered, but template DNA must be grown out. Template DNA will be grown and extracted by James should we later decide that Citrine will be needed.
*Note that mCherry and Citrine both have restriction sites within the coding region, and are therefore not optimal. Advice/help on this issue would be appreciated.
Another Digest was done [http://www.jhu.edu/iGEM/Group1:FluorescentProteins/2008-8-19.mCherry%20and%20YFP%20Digest%20Gel.Ingrid%20Spielman.html mCherry and YFP Digest Gel] and weird lines exist.
GROUP 2: MATa Specific-promoters
Summary for MATa Specific Promoters Group
Date: August 19, 2008 Status report by: Allison and Nate Part no.: BBa_K110008 -> BBa_K110016 Part Description: A promoters: MFA1 (L+R) and Ste2 (R+L), respectively. Sequences were analyzed. BBa_K110016 had a perfect clone. Since there is not much miniprep left, a transformation was done to generate more clones with the correct sequence. BBa_K110008 had one mutation. Another transformation into a Kan BioBrick vector was attempted but was unsuccessful.
GROUP 3: Short Two-Way Stops
Summary for Short Two-Way Stops Group
Date: August 25, 2008 Status report by: James Part no.: BBa_K110011 -> BBa_K110013 Part Description: Short Two way Stops Summary: Sequence files from parts sent for sequencing showed incorrect sequences for 3/4 biobricks sent in. However 1 clone of BBa_K110012 was correct. That clone was cut and ligated into iGEM vector. A PCR will be tried again for 11-->13, however direct ligation into iGEM vector will be attempted to evade problems with incomplete products ligating into PGEM-T.
The Two way stop biobrick was then attached to the end of the Fluorescent Protien Venus YFP, using iGEM standard assembly. This Venus YFP had come from iGEM headquarters, as we as still waiting for sequence verification of our biobricks. We have yet to run the product on the gel, but the expected band length should be around 900bp. (700bp Fluorescent Protein + 200bp Two way stop)
GROUP 4: Long Two-Way Stops & MAT(alpha) Specific Promotors
Summary for Long Two-Way Stops & MAT(alpha) Specific Promoters Group
Date: July 29, 2008 Status report by: Jaime Part no.: BBa_K110001, BBa_K110003, BBa_K110005, BBa_K110006 Part Description: Long Two-way Stops & Mat(alpha) specific promotors [http://www.jhu.edu/iGEM/Group4:LongTwo-wayStopsANDMATalphaSpecificPromoters/2008-7-25.Restriction%20Enzyme%20Digest%20of%20Mini-Preps.Jaime.html Restriction Enzyme Digest of Mini-Preps] Summary here: Need to be sequenced.
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). Alll gave expected results. 1 ug of each vector was digested for future use. Gel of digestion shows DNA is correct.([http://www.jhu.edu/iGEM/Group6:Vectors/2008-8-12.Digest%20of%20vectors,%20ready%20for%20distribution.Tejas.html Vectors ready for insertions])
GROUP 7: Microscopy/Yeast
Summary for Microscopy/Yeast Group
