A crystallizable, purified chondroitinase ABC having a molecular weight of about 100,000 dalton by the measurement of the SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and the measurement by the gel permeation chromatography method, having alanine as the N-terminal amino acid and proline as the C-terminal amino acid is disclosed. A process for the purification of the crystallizable purified chondroitinase ABC comprising removing nucleic acid from an surfactant solution extract obtained from cells of chondroitinase ABC-producing microorganisms and chromatographically treating by concentration gradient elution using a weak cation exchange resin or a strong cation exchange resin is disclosed. A composition comprising a chondroitinase and serum albumin, gelatin, or a nonionic surfactant is used to treat disc displacement. The enzyme is isolate from Proteus vulgaris ATCC 6896.

摘要:
In the present invention, a petroleum fraction containing arsenic is brought into contact with an adsorbent comprising a substrate such as an active carbon, bituminous coal or organic polymeric compound having introduced therein a sulfur element, particularly represented by mercapto moiety, and therefore arsenic in the petroleum fraction can be removed at a high percent removal by means of simple equipment, and, even if highly reactive olefins are contained in the petroleum fraction, these olefins do not polymerize, thus troubles do not occur.
摘要:
A method for transferring an image from an image sheet to an image-receiving sheet while the sheets are superposed, and an apparatus therefor. A support plate of good thermal conductivity and rigidity is placed against the sheets, and a cover sheet superposed remotely from the support plate. The resulting assembly is passed through a pair of heated rollers. Cooling rollers may cool the superposed sheets following image transfer. Additional cooling may be provided.
