− | We constructed ATF2 generator. (BBa_K1049002)
| |
− | Our team KIT-Kyoto 2013 constructed this part for the purpose of measurement. T7 promoter is an IPTG-inducible promoter. We added 20uL IPTG (100mM) to our genetically modified E.coli after cultivation at 28 and 37 degree C. 2 hours after, we extracted soluble proteins from it by using FastBreak™ Cell Lysis Reagent and did SDS-polyacrylamide gel electrophoresis.

− | ATF2 gene encodes AATase, which is about 62kDa. The consumption of protein marker is like this.

− | β‐Galactosidase 120kDa
| |
− | Bovine Serum Albumin 95kDa
| |
− | Glutamine dehydrogenase 68kDa
| |
− | Ovalbumin 50kDa
