The present invention provides an antibody that specifically binds to human CD69, has an activity to suppress allergic inflammation, and has cross-reactivity with mouse CD69. In addition, the present invention provides an antibody having high binding affinity for human CD69 and an activity to suppress allergic inflammations. The antibody of the present invention can be a human antibody.

Anti-human CD69 antibody, and use thereof for medical purposes

The present invention provides an antibody that specifically binds to human ADAM28, inhibits enzyme activity of human ADAM28, and has an activity to suppress metastasis of a cancer cell that expresses human ADAM28. The antibody of the present invention can be a human antibody.

The invention provides a method of producing a protein multimer-nucleic acid complex comprising a protein multimer and any one target component of the protein multimer. A nucleic acid encoding the target component is subjected to in vitro translation to provide a translation product containing a target component-nucleic acid complex of the target component and the nucleic acid encoding the target component. A nucleic acid encoding a non-target component constituting the protein multimer together with the target component is translated into the non-target component by adding the nucleic acid encoding the non-target component to the previously provided translation product to provide the non-target component. The non-target component then is associated with the target component contained in the target component-nucleic acid complex to form a protein multimer, thus affording the protein multimer-nucleic acid complex of the protein multimer and the nucleic acid encoding the target component.

Efficient method for displaying protein multimer

Provided is an antigen-binding protein prepared merely by a method of in vitro selection using the RNF8-FHA domain, which has no intramolecular disulfide bond and functions in cells as it is. One to four loops extending from the FHA domain are randomized, and a recognition site for a target molecule is artificially created on the FHA domain surface to construct an RNF8-FHA domain library. Using the library, an antigen-binding protein is efficiently selected in vitro.

The present invention provides a method of producing a maturated oligonucleotide library, including a step of obtaining a terminal-modified product of a maturation target oligonucleotide library, including adding a tag sequence to the 5' terminus of the maturation target oligonucleotide library and an arrest sequence, which stalls translation elongation on a ribosome, to the 3&#x2032; terminus of the maturation target oligonucleotide library, a step of transcribing the terminal-modified sequence product to give a transcript, and a step of in vitro translation for translating the transcript in vitro, wherein the maturation target oligonucleotide library is a random oligonucleotide library.
