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
Status Report 2.2 - 07/17/08
Status Report 2.3 - 08/07/08
Please BOLD the most recent step that you have completed. Do this by placing the tag < b > in front of and </ b > at the end of what you would like to be placed in bold (with no space between letter and carrot symbol (<,>).

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.
September 2: Transformation into a Kan BioBrick was completed and assembly of MFA1 (L+R) to YFP will take place soon.
GROUP 3: Short Two-Way Stops
Summary for Short Two-Way Stops Group
Date:September 2,2008 Status report by: Raghav and James Part no.:BBa_K110012, E2030, BBa_K110008 Part Descriptin: Short one-way stop (BBa_K110012 was found to be a 1-way stop), YFP, a-promoter Summary: We cut the Chlor vector containing one-way stop 12.3 and YFP (Left to right) with XbaI and PstI. We then ligated the MFa1 (Left to right) with 12.3 and YFP in a Kan vector, transformed it in DH5alpha competent cells. We performed a miniprep on successful white colonies (low concentrations ~100 ng/ul) and perfomed a restriction digest on the Kan vector with EcoRI and PstI. Unfortunately, we did not see any bands on the gel. We are currently repeating the miniprep and digest.
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])
