Cloning of protein Z DNA to OmpA constructs Michał K.
- Digest and dephosphorylation (with CIAP) of pACYC177+OmpA_alpha with SacI and NotI.
- Gel eloctrophoresis and gel-out (4300 bp band).
-
Ligation of isolated DNA fragment and Z DNA fragment isolated on 10 July.
- Transformation of E. coli TOP10 strain with ligation.
- Transformants plating on LB + kanamycin.
Preparation of alfa+A conctruct Antoni
- Protein A PCR on pKS+A
- PCR on alpha
- Gel electrophoresis
- Gel-out
- PCR on alpha+A
Cloning of protein Z DNA to OmpA constructs
- Digest of Geneart_Z and pACYC177+OmpA_omega with SacI and NotI (pACYC177 was also dephosphorylated with CIAP)(3 hr).
- Gel electrophoresis and gel-out of proper bands 220 bp (for Geneart_Z lane)and 4050 bp (pACYC177+OmpA_omega lane).
- Ligation of pACYC177+OmpA_omega and Z (1 hr).
- Transformation of E. coli TOP10 strain with ligation.
- Transformants plating on LB + kanamycin.
Cloning of protein Z DNA to OmpA constructs
2 colonies was inoculated to liquid LB broth with kanamycin
Phage Outbreak
Michał L., Ewa, Marcin
We have massive outbreak of some virulent bacteriophage strain in our lab. All our current E. coli cultures are gone :-(. Until we get rid of the phage there will be no microbiological work in our lab. Sorry.
Cloning omega-A fusion on pKS (second attempt)
Michał L., Ewa, Marcin:
We had to start form scratch with this one.
- PCR A in 50 µl
template DNA - pKS-A4 1 µl
primer
AP+NotI_N - 2 µl
primer
AL+link10+homo2_N - 2 µl
Pfu polymerase buffer + Mg2+ (from Fermentas) - 5 µl
dNTPs - 1 µl
Pfu turbo - 0.5 µl
H2o - 38.5 µl
Program:
- 95°C 3'
- 95°C 30"
- 62°C 45"
- 72°C 45"
- 72°C 10'
- keeping in 4°C
- PCR omega in 50 µl
template DNA - pUC19 1 µl
primer OmegaLS - 2 µl
primer AOmegaPli - 2 µl
Pfu polymerase buffer + Mg2+ (from Fermentas) - 5 µl
dNTPs - 1 µl
Pfu turbo - 0.5 µl
H2o - 38.5 µl
Program:
- 95°C 3'
- 95°C 30"
- 62°C 45"
- 72°C 45"
- 72°C 10'
- keeping in 4°C
25 cycles
- Gel electrophoresis
- Reisolation from agarose gel
Preparation of constructs with OmpA protein fusions and Cloning of protein Z DNA to OmpA constructs
- <a href="https://2008.igem.org/wiki/index.php?title=Wiki/Team:Warsaw/protocols#plasmid_DNA_isolation">Isolation of plasmids</a> from cultures inocluated on previous day (pCACYC177 + OmpA_alpha and pACYC177+OmpA_Z_omega).
- Control
<a href="https://2008.igem.org/Wiki/Team:Warsaw/igem_notebook.htm#digest">digest</a> of isolated plasmids with BamHI and SacI (we found good clones for both ligations).
