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. (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. (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, (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. 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.
GROUP 2: MATa Specific-promoters
Summary for MATa Specific Promoters Group
Date: August 5, 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 will be done to generate more clones with the correct sequence. BBa_K110008 had one mutation; additional minipreps from other clones are ready to send off for sequencing, although the DNA concentrations are low. Colonies can be picked and overnight cultures grown for another round of minipreps.
Date: July 29, 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. Two samples of mini preps from MFA1 and Ste2 were sent off for sequencing at the end of last week. Results will follow soon.
GROUP 3: Short Two-Way Stops
Summary for Short Two-Way Stops Group
Date 8/5/08 Status report by: James Part no.: BBa_K110011 -> BBa_K110013; BBa_K110010;17 Part Description: Short two way stops; and Sapphire Fluorescent Proteins Summary: The sequence data from last week, turned out all right both orientations of Sapphire FP should be correct sequences Sequence Data HOORAY! Last weeks miniprep and digestion yielded no DNA, so this week the minprep was repeated and the digestion of the prodeuct can be found here RE digest Two way stop digestion 8/05/08
Date 7/29/08 Status report by: James Part no.: BBa_K110011 -> BBa_K110013; BBa_K110010;17 Part Description: Short two way stops Summary: Sequencing of BBa_K110010;17 (Sapphire FP) revealed confusing, if not bad sequences.Sequence Data PCR cloning and transformation was completed sucessfully last week on the Short two way stops A Miniprep was done and a RE digest will be completed soon (possibly tonight)
Date: 7/22/2008 Status report by: James Part no.: BBa_K110011 -> BBa_K110013 Part Description: Short two way stops Summary: RE digestion showed no insert the plasmid of our clones, thus the PCR was done again. Short way stops
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 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: _________ __, 2008 Status report by: _____ Part no.: BBa_K1100XX -> BBa_K1100YY Part Description: Summary here.
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. To produce sufficient quantities of thee vectors, I grew out the strains and performed several minipreps. Total amount of DNA is estimated between 5 to 20 ug per vector. Restriction digests confirmed the extracted DNA was vectors. (Vectors after Digestion with EcoRI and PstI) Transformation into DB3.1 competent cells was unsuccessful, likely due to the possibility that the competent cells may not actually be DB3.1. Currently making new competent cells from old DB3.1 strain (BB #5777) and from new DB3.1 strain (BB #2198).
GROUP 7: Microscopy/Yeast
