    摘要: A protein comprising an amino acid sequence represented by SEQ ID NO: 1 in the Sequence Listing and originating in human MP52 and the dimer of this protein. This dimer protein can be obtained by constructing a plasmid containing a DNA wherein a codon encoding methionine is added to the 5' end of a DNA sequence encoding the above-mentioned aminoacid sequence, transforming Escherichia coli by this plasmid, incubating the E. coli transformant, solubilizing and purifying the obtained inclusion body to thereby give a monomer protein, and then renaturing the obtained monomer protein into the dimer followed by purification. This dimer protein is useful in the treatment of cartilage and bone diseases.

    摘要: The present invention relates to a process for the production of purified dimeric bone morphogenetic factors. Purified dimeric bone morphogenetic factor can be produced by subjecting an inclusion body of a bone morphogenetic factor produced by means of a genetic engineering technology to the following steps a) - e) in order;

    a) treating an inclusion body of a bone morphogenetic factor with a denaturing agent to obtain a solubilized monomer,
    b) treating the solubilized monomer with a refolding solution to obtain a dimeric bone morphogenetic factor,
    c) treating the dimeric bone morphogenetic factor by ultrafiltration and substitution of solvent,
    d) subjecting the dimeric bone morphogenetic factor in solvent thus substituted to isoelectric precipitation, and
    e) subjecting the dimeric bone morphogenetic factor thus isoelectrically precipitated to reverse-phase chromatography.

    摘要: A method for preparing a sperm containing an exogenous DNA, wherein the exogenous DNA together with liposome for the purpose of transduction of DNA into mammalian cells is injected repeating three times or more into a testis of a mature non-human vertebrate male and the sperm containing the exogenous DNA is produced in the testis of said male. It can be convenient and efficient to prepare a non-human transgenic vertebrate by mating a sperm containing an exogenous DNA with a female naturally, or mating an egg which has not yet been fertilized by artificial insemination or in vitro fertilization.
