week 06/04/12 - 06/10/12

• Golden-Gate-Cloning-Reaction (GGC) to assemble a 12-repeat-TAL-TF, that recognizes the sequence TACATTGGACCTAT --> protocol: sanjana et al. (first hexamers...) • transformation: GGC-reaction • making aliquots of ordered GGC-Primers (freiGEM-method) • making aliquots of ordered, i.e. synthesized, direpeats • extension-PCR of direpeats with ordered freiGEM-GGC- • PCR-Purification of extension-PCR • mutagenesis-PCR of Zhang-plasmid to remove restriction sites (SpeI, PstI, EcoRI, XbaI) --> making the plasmid work

 with iGEM-standard

week 06/11/12 - 06/16/12

• optimizing PCR conditions for extension of direpeats • redoing GGC-reaction --> protocol: sanjana et al. • transformation of redone GGC-reaction • GGC á la freiGEM --> transformation • testing of iGEM-distribution kit

week 06/17/12 - 06/23/12

• cloning of direpeats into pJET 1.2 vector-system • colony-PCR of freiGEM-GGC product • place sequencing order for freiGEM-GGC

week 06/24/12 - 07/01/12

• optimizing of freiGEM-GGC under various conditions • transformation of pJET-direpeats into bacteria • using the iGEM distribution kit: Bba_A12564 (CMV+Luc) --> reporter-plasmid for DNA-methyl-transferase testing • Miniprep of GGC-transformation (1 successful)

week 07/02/12 - 07/08/12

• extension-PCR with all 96 direpeats on one well-plate • transformation • PCR-amplification of all 4 iGEM-backbones --> testing different conditions • making bacteria competent for transformation

week 07/09/12 - 07/15/12

• digest of exDirepeats with XbaI and PstI • nanodrop of exDirepeats • ligation of exDirepeats in psB1C3 vector backbone and then transformation • colony-PCR, gel run, making cultures • miniprep of some of the 96 exDirepeats

week 07/16/12 - 07/22/12

• Transformation of synthesis products (Dnmt, hyperactive Gin, Gin L7C7, Tn3 and TAL-ORF) into DH10B-strain competent cells • amplification of psb1c3 vector backbone, then gel-run and gel-purification • picking of colonies (transformation of synthesis-products) • miniprep of synthesis-products • repeat of pcr-amplification of psb1c3 vector backbone

• GGC to produce freiGEM-Mammo-Brick with CMV-promotor, Puromycin-resistance and postORF and TALEN-NG-vector backbone • to do so a extension-PCR on the parts was done • CMV-Promotor was taken out of iGEM Distribution Kit 2012

week 08/06/12 - 08/12/12

• mutagenesis-PCR of pcb1c3 vector backbone to eliminate restriction site for BsmBI • repeat of GGC to get MammoBrick • gel-run of mutagenesis-PCR of psb1c3
