Title: Method for purifying protein
Inventor: KIKUCHI MASAYOSHI
IPC: C12N15/09
Filed: 1991-04-18
Abstract: PURPOSE:To purify a protein such as a diagnostic agent for hepatitis C, etc., without decomposing microbial cell protease by extracting a human hepatitis C virus core antigenic protein produced by Escherichia coli with a specific buffer solution and then carrying out gel filtration thereof with a specified buffer solution. CONSTITUTION:Escherichia coli HCVKMR3 (FERM P-11569) transformed by inserting a plasmid pKMR3 containing a gene capable of coding a human hepatitis C virus core antigenic protein or a protein containing its core antigenic region is cultured in a culture medium at 37 deg.C for 2hr to centrifuge the culture solution. Microbial cells are then collected and pelletized. The resultant pellets are subsequently suspended in a buffer solution containing 2-mercaptoethanol and guanidine hydrochloride and subjected to ultrasonic treatment to extract the produced protein. The obtained extract solution is then centrifuged, subjected to gel filtration chromatography in the presence of a buffer solution containing the guanidine hydrochloride and purified. Thereby, the human hepatitis C virus core antigenic protein or the protein containing its core antigenic region is purified.

Abstract: PURPOSE:To prevent the crack generation of a lining member and weld zone by forming a recessed stepping part at a nonuniform sectional part and arranging the clad steel of the combination of the same material with a base metal at the stepping part. CONSTITUTION:In case of arranging a lining member at the nonuniform sectional part of a tube plate 1, etc., the clad steel of the lining cladding member 10 of a high corrosion resistance of a Ti, etc., and the lining base metal 11 of the same material as that of a tube plate 1 is employed for the lining member. The stepping in a recessed shape is executed in advance at the tube plate 1 side and the clad steel is installed at the stepping part. In this case, the cladding member 4 and joint member 12 of the same material are welded by arranging at the both end parts of the lining cladding member 10. The lining base metal 11 is welded to the tube plate 1. A gap 9 becomes about zero due to the base metal 11 being worked in the same shape as that of the tube plate 1. The stress generation of the lining member and a weld zone 3 is reduced and the crack generation is prevented because the base metal 11 of the clad steel is formed by the same material as that of the tube plate 1.

Abstract: PURPOSE:To remove effect of a leakage electric field of an electrostatic deflection plate with the ion passage electrode length thereof sufficiently larger than an interval of the deflection plate, by providing an acceleration electrode between a displacement electromagnet and the electrostatic deflection plate to accelerate neutral particles ionized. CONSTITUTION:Neutral particles 6 made incident into a vacuum container 1 from a nuclear fuser not illustrated are ionized with charge exchange by a neutral gas in a stripping cell 2 and turned to ions (f). The incident ions (f) perform a rotary motion with the radius corresponding to energy by a Larmor's motion with a deflection electromagnet 3 to enable discrimination of momentum. An acceleration electrode 7 is provided between the electromagnet 3 and an electrostatic deflection plate 4a for discrimination of mass. This allows a larger electrode length (e) of the electrostatic deflection plate 4a to remove effect due to a leakage electric field at an end thereof 4a thereby achieving a mass spectrograph with limited errors even with respect to neutral particles with a low energy. Thus, the momentum and mass of the incident particles 6 are measured depending on which position the ions (f) reach on a particle detector 5.

Abstract: PURPOSE:To lower the progression speed of cracks and to prolong the life of the device by circumferentially providing plural pieces of hollow grooves having a circular or elliptical section nearly in parallel with the end parts of the joint surfaces of armor tiles and a supporting base plate on these joint surfaces. CONSTITUTION:The grooves having the semicircular or semielliptical section parallel with the circumferential direction of the end parts 13a of the respective joint surfaces are formed on the joint surface 13 side of the armor tiles 10 and the joint surface 13 side of the supporting base plate 11. The respective surfaces are butted against each other and are metallurgically joined. The hollow grooves 13b parallel with the circumferential direction of the end parts 13a are formed on the surface 13 in this way. The cracks are generated at the end parts 13a by repetitive thermal load and develop along the surface 13 but stagnate upon arrival at the groove parts 13b. The progression of the cracks along the surface 13a is, therefore, weakened and the life is prolonged. Crack detecting grooves are provided by a similar method and are kept monitored at all times to prevent an accident.
