Abstract: A novel humanized antibody against the CD34 surface antigen on the human stem cells is provided. The humanized antibody contains a heavy chain variable region comprising an amino sequence as set forth in SEQ ID No. 1 and a light chain variable region comprising an amino sequence as set forth in SEQ ID No. 2. The disclosure also provides the applications of the disclosed humanized antibody.

Abstract: An amino acid sequence of a humanized monoclonal antibody includes an amino acid sequence of a light chain variable region, which includes SEQ ID. NO.: 1; and an amino acid sequence of a heavy chain variable region, which comprises SEQ ID. NO.: 2, wherein SEQ ID. NO.: 1 and SEQ ID. NO.: 2 have at least one amino acid substitution which is selected from a group consisting of isoleucine at position 10 of SEQ ID. NO.: 1, being substituted with threonine, lysine at position 18 of SEQ ID. NO.: 1, being substituted with arginine, lysine at position 2 of SEQ ID. NO.: 2, being substituted with glutamine, tryptophan at position 10 of SEQ ID. NO.: 2, being substituted with leucine, lysine at position 18 of SEQ ID. NO.: 2, being substituted with arginine and glutamic acid at position 41 of SEQ ID. NO.: 2, being substituted with glycine.

Abstract: A tool box includes a plastic case formed by way of blow molding and a flexible piece is integrally formed on an outside of the plastic case during processes of the blow molding. The flexible piece is connected to an inside of a female mold and the melted plastic material is inflated and matches the insides of the male and female molds. The flexible piece is securely connected to the melted plastic material high temperature and pressure so that flexible piece and the melted plastic material are not separated. After the tool box is formed, the tool box includes an anti-slip and flexible piece on the outside thereof.
