Abstract: The present invention relates to a method for producing recombinant human prethrombin-2 protein and having human ?-thrombin activity by the plant-based expression systems.

Abstract: A staining kit is provided, including a first pattern including antibodies against T cell, B cell, NK cell, monocyte, regulatory cell, CD8, CD45, and CTLA4; a second pattern including antibodies against T cell, B cell, NK cell, monocyte, regulatory cell, dendritic cell, and CD45; a third pattern including antibodies against T cell, B cell, NK cell, monocyte, CD8, CD45, CD45RA, CD62L, CD197, CX3CR1 and TCR??; and a fourth pattern including antibodies against B cell, CD23, CD38, CD40, CD45 and IgM, wherein the antibodies of each pattern are labeled with fluorescent dyes. A method of identifying characterized immune cell subsets of a disease and a method of predicting the likelihood of NPC in a subject in the need thereof using the staining kit are also provided.

Abstract: A composite single structured hard disk drive, comprising: a machine casing having a power port and two signal I/O (input/output) ports at an outer surface thereof; an interior of the machine casing having a driving unit which is electrically connected to the power port; the driving unit being able to rotatably drive at least one recoding disk; two read/write modules (R/W modules) being installed, respectively, each R/W module having a rotatable arm set and a dynamic unit connected to the rotatable arm set; one end the rotatable arm set having at least one R/W head at a front end thereof; another end of the rotatable arm set having no the R/W head is connected to the dynamic unit; the dynamic unit being connected to the power port and being controlled by a processor in the substrate in the machine casing.
