MutD₅ testing

Piotr

Sequencing results: there weren't any mutations in plasmids isolated from MutD₅ - maybe this strain is too weak as a mutator.

Preparation of pACYC177 + OmpA-linker-omega-linker (BBa_K103016)

Michał K.

1. PCR on pACYC177+OmpA_omega_ΔA_alpha plasmid using OmLNXNEB and LinPBSNP primers (annealing temperature 58 °C; elongation length 90s) to obtain OmpA-linker-omega-linker (BBa_K103016) fragment.
2. Gel electrophoresis of PCR products and gel-out of proper bands (OmpA-linker-omega-linker - 900 bp).

Preparation of pSB1A3+Omp_

Michał K.

1. Digest of pSB1A3 carrying ΔA (BBa_K103003) plasmid with NdeI and SacI (BamHI buffer). Dephosphorylation (CIAP) of plasmid.
2. Gel electrophoresis of digested plasmids and gel-out of proper band (pSB1A3 - 2200 bp).
3. Overnight ligation of isolated DNA fragments: pSB1A3 + OmpA_linker (BBa_K103006) (from 18 September).

Preparation of BioBricks

Michał K.

1. Digest of pGeneArt-Z and pSB1A3 carrying ΔA (BBa_K103003) plasmids with NdeI and BcuI (BamHI buffer).
2. Dephosphorylation (CIAP) of plasmids.
3. Gel electrophoresis of digested plasmids and gel-out of proper bands (Z - 200 bp and both pSB1A3's - 2200 bp).
4. Overnight ligation of isolated DNA fragments: pSB1A3 + Z (BBa_K103004) and pSB1A3 + OmpA_linker (BBa_K103006) (from 18 September).
5. PCR on pACYC177+OmpA_omega_ΔA_alpha plasmid using PlacL_XNE and LinP_BS primers (annealing temperature 58 °C; elongation length 90s) to obtain pLac_OmpA_omega fragment.
6. PCR on pACYC177 + OmpA_omega plasmid using OmegLNde and LinP_BS primers (annealing temperature 55 °C; elongation length 60s) to obtain omega_link fragment.
7. Gel electrophoresis of PCR products Fig. 1 and gel-out of proper bands (ΔA - 250 bp, pLac_OmpA_omega_ - 1200 bp, omega_linker - 350 bp and OmpA_omega_ - 900 bp).

Preparation of vectors for Biobricks
