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.
