  • Patent number: 10316074
    Abstract: The present invention relates to an interleukin-2 expression construct for yeast, comprising a methanol oxidase (MOX) promoter; a human serum albumin gene or a fragment thereof; and an interleukin-2 (IL-2) gene, and to a yeast comprising the expression construct. The interleukin-2 expression construct for yeast according to the present invention makes it possible to produce an expressed and secreted fusion protein of human serum albumin (HSA) and interleukin-2 at low costs and easily separate recombinant interleukin-2 from the fusion protein. Thus, the interleukin-2 expression construct for yeast may be effectively used to produce a large amount of recombinant interleukin-2 with high purity.

  • Publication number: 20180237488
    Abstract: The present invention relates to a method for producing an interleukin-2 protein using methylotrophic yeast. The method for producing interleukin-2 according to the present invention shows high cell growth and protein synthesis rates by use of the established optimal cell line, and produces a large amount of a protein comprising interleukin-2 by use of the established optimal culture conditions utilizing methanol that is an inexpensive carbon source. In addition, the method according to the present invention isolates and purifies the protein by a simple process. Accordingly, the method according to the present invention highly pure interleukin-2, and thus has a significant effect on the mass-production of interleukin-2.

  • Patent number: 10019576
    Abstract: A security control system is provided that works as an extra layer of defense as a way to prevent an “attack” that is initiated by modifying either the “jump” or the “return” addresses or both. The principal behind the security control system is to “monitor” the addresses to which the processors would jump, interrupt or return, and identify when these addresses are modified in a manner that does not comply with the normal execution of the processor. In order to do that the security control system uses existing structures in multi-core processors and even anticipates the creation of additional structures to expedite and improve such control.
