  • Publication number: 20150337440
    Abstract: A coating method which reduces damage of a barrier layer is provided. The barrier film has a gas barrier property improved by suppressing reduction of a water vapor transmittance rate through a non-contact coating method on a barrier layer when a protective coating is performed to protect a barrier layer of the barrier film.

  • Patent number: 8957196
    Abstract: Disclosed herein is an inducible high-expression cassette comprising a dihydrofolate reductase (DHFR) promoter from which GC-rich repeat sequences are partially or entirely removed, the cassette capable of more effectively improving a gene amplification system. Also disclosed are an expression vector comprising the inducible expression cassette and optionally a gene encoding a recombinant protein of interest, an animal cell line transformed with the expression vector, and a method of mass producing and purifying a recombinant protein by culturing the transformant. The present invention enables the shortening of the time required to establish a cell line producing a recombinant protein of interest at high levels using a low concentration of a DHFR inhibitor, thereby allowing more effective production of the recombinant protein.

  • Patent number: 7131883
    Abstract: A field emission display (FED) and a manufacturing method thereof are provided. The FED includes a getter portion isolated outwardly from an active display region. This getter portion includes a non-evaporable getter layer for absorbing gas and an electron emission source for activating the getter layer. Accordingly, by activating the non-evaporable getter, the gas generated in the display is easily absorbed, and the FED is maintained in a high vacuum state.
