Abstract: The present invention relates to the biotechnology field, more particularly, to novel recombinant staphylokinase (RGD/KGD-Sak) derivatives and the preparation the thereof. The derivatives, have a low polymerizing ability, low immunogenicity and a bifunctionality of thrombolytics and anticoagulant. Based on the trimensional structural analysis of the monomer and dimer of recombinant staphylokinases and their biochemical properties, we designed two novel bifunctional staphylokinase molecular structures. Mutant genes were constructed by PCR site-directed mutagenesis, which were then recombined with a prokaryotic vector and used to transform E. coli. Engineered strains with a high expression level were selected by screening and propagated by fermentation, followed by disruption of the cells, centrifugation to collect inclusion bodies, renaturation, and purification of RGD/KGD-SAK through a two-step method. After lyophilized, the polymerizing ability and immunogenicity of the products decreased significantly.

Abstract: A display device using an organic light emitting element is provided which is structured so as to ensure excellent display performance by avoiding dot defect and improve long-term reliability. The distance between an organic light emitting element and a sealing substrate is controlled using the top of a bank that is placed in a pixel portion and the top of an insulating film that is placed in a driving circuit portion. As a result, a gap is provided between the organic light emitting element and the sealing substrate and a damage to the organic light emitting element can be avoided. Furthermore, the sealing substrate can be as close to an element substrate as possible, thereby keeping the amount of moisture that enters the display device from its sides small.
