摘要:
An objective of the present invention is to provide methods of producing human collagen molecules that are easy to isolate and purify and that have a structure substantially equivalent to that of a natural collagen molecule, wherein host cells that are transduced with a collagen gene synthesize large amounts of human collagen protein derived from a gene introduced into a high exogenous gene expression vector. Another objective of the present invention is to provide collagen molecules produced by the production methods.The present inventors discovered that a large amount of human collagen hardly contaminated with host cell-derived collagen could be produced, by selecting from various mammalian cells a host cell that has low collagen expression and introducing a collagen gene construct into a vector capable of high exogenous gene expression.

A digested phagocyte prepared by contacting in vitro a phagocyte with a foreign microorganism and isolating the phagocyte so contacted; a process for producing the same; and a process and a kit in which these are utilized are disclosed. An experimental model, which enables in vitro evaluation of a phagocytotic function of phagocytes, is provided.
摘要:
A probe derived from bacteria of pneumonia, containing fragments of DNA which streptococcus pneumoniae essentially possesses, and useful for detecting and identifying causative bacteria of pneumonia is obtained by completely digesting the DNA with a restriction endonuclease PstI, followed by cloning into a suitable vector.

The DNA from the bacteria Streptococcus pyogenes is extracted, then completely digested with restriction enzyme HindIII, followed by cloning into a suitable vector to select a probe comprising DNA which is essentially contained in Streptococcus pyogenes, then the sequence of the probe is elucidated.
摘要:
The invention aims at improving the uniformity in gap between an array substrate and a color filter substrate of a liquid crystal display device to be manufactured by a multi-panel forming process filling liquid crystal by a liquid crystal dripping method. A liquid crystal display device of the invention comprises an array substrate having a plurality of first seal frames each forming a panel area to become a display portion and a second seal frame containing these seal frames thereinside and being of a completely closed shape as a whole outside these first seal frames. The liquid crystal display device of the invention has a structure in which the whole inside of the second seal frame including the insides of the first seal frames of the array substrate is filled with liquid crystal by a liquid crystal dripping method and thereafter the color filter substrate is stuck on the array substrate. The invention makes it possible to manufacture a liquid crystal display device of an aggregate liquid crystal display panel structure improved in uniformity of gap between both substrates by means of this structure.
