Abstract: A semiconductor laser device comprises a stem serving as a base; a laser diode LD submount having surface electrodes arranged thereon and joined to the surface of the stem; an LD chip joined to the surface electrode and connected with the surface electrode; and leads fixed in through holes formed in the stem by means of sealing parts and electrically connected to the surface electrodes via embedded layers in via holes formed in the LD submount, wherein grooves are formed in portions of the sealing parts or in portions of the LD submount around the connections between the leads and the embedded layers, to obtain a good modulated light waveform.

Abstract: An inducing agent or enhancing agent, for the expression of HM1.24 antigen in hematopoietic tumor cells, comprising interferon ?, interferon ?, or the IRF-2 protein as an active ingredient, as well as an antitumor agent for hematopoietic tumors which comprises a combination of said inducing agent or enhancing agent and an antibody against HM1.24.

Abstract: A cancer vaccine containing as an active ingredient an antigen-specific dendritic cell pulsed by an HM1.24 protein, HM1.24 peptide or transduced with an HM1.24-encoding gene, or HM1.24 protein-encoding DNA or RNA.

Abstract: An enhancer of expression, in the myeloma cell, of HM1.24 antigen, said enhancer comprising interferon-? or interferon-?, or IRF-2 protein as an active ingredient. Interferon-? or interferon-? is expected to enhance the expression of HM1.24 antigen by activating the promoter of a gene encoding HM1.24 antigen.

Abstract: There are provided a genomic DNA comprising 4 exons encoding the amino acid sequence as set forth in SEQ ID NO: 2 and 3 introns ligating them, and a splicing variant of said genomic DNA; as well as a DNA having the base sequence as set forth in SEQ ID NO: 4 and a promoter activity and the fragment thereof, and uses thereof.

Abstract: A reshaped human anti-HM 1.24 antibody comprising: (A) an L chain comprising (1) the C region of a human L chain, and (2) the V region of an L chain comprising the FR of a human L chain and the CDR of the L chain of a mouse anti-HM 1.24 monoclonal antibody; and (B) an H chain comprising (1) the C region of a human H chain, and (2) the V region of an H chain comprising the FR of a human H chain and the CDR of the H chain of a mouse anti-HM 1.24 monoclonal antibody. Since most of this reshaped human antibody is derived from human antibody and the CDR has a low antigenicity, the reshaped human antibody of the present invention has a low antigenicity and, therefore, is expected to be-used for medical treatment.
