摘要:
Prepared is an extract composition having an improved protein synthetic activity in a cell-free protein synthesis system using a mammalian cultured cell extract. An eukaryotic translation initiation factor and/or translational regulator are added to a cell-free protein synthesis system comprising an extract prepared from cultured mammalian cells and a template mRNA. These factors are one or more selected from the group consisting of eukaryotic translation initiation factors 4E (eIF4E), 2 (eIF2) and 2B (eIF2B), and eukaryotic translational regulator p97.

摘要:
Provided is a process for producing a protein with post-translational modification in a cell-free protein synthesis system having a higher protein synthetic activity and glycosylation capability. The process of the present invention comprises preparing a cell extract from cultured cells of an immortalized mammalian cell line that has enhanced protein secreting activity, and adding an mRNA encoding a glycoprotein to the cell extract.

摘要:
Wavelength division multiplexed optical signals with different wavelength dispersion are compensated for wavelength dispersion in a optical transmission line. Each multiplexed wavelength .lambda.1-.lambda.n is selected by band pass filters 11-1-11-n. The selected optical signal for each wavelength is independently compensated for the wavelength dispersion by wavelength dispersion compensation sections 12-1-12-n. The wavelength dispersion compensation section of each wavelength has a optical fiber having a dispersion value with polarity opposite to that of the optical transmission line. Zero dispersion is attained for each wavelength .lambda.1-.lambda.n as a whole, and transmission distance of wavelength division multiplexed optical signals can be extended.
