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:
A metal complex having a structure of the following general formula (1): (wherein, X1 and X2 represent independently a carbon atom or nitrogen atom. Bonds represented by X1C and X2N are a single bond or double bond. M represents a transition metal atom. A dihedral angle defined by a plane containing a structure represented by CX1—X2 and a plane containing a structure represented by X1—X2N is 9° to 16°, and the proportion of the sum of squares of orbital coefficients of the outermost d orbital of the metal atom M, in the highest occupied molecular orbital of the metal complex, occupying with respect to the sum of squares of all atom orbital coefficients, is divided by an energy difference S1−T1 between the lowest excitation singlet energy S1 and the lowest excitation triplet energy T1 of the metal complex, to give a value of 200 to 600%/eV.).

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.
