Abstract: A monoclonal antibody or an antigen-binding fragment thereof according to an embodiment of the present invention can bind to lymphocyte-activation gene 3 (LAG-3) including a heavy chain variable region and a light chain variable region and inhibit the activity thereof. Thus it is expected to be useful for the development of immunotherapeutic agents for various disorders that are associated with LAG-3.

Abstract: A card wallet for a mobile phone is disclosed. The card wallet includes a rear part having a rectangular shape corresponding to a card and being in surface contact with a rear surface of the mobile phone, a front part opposed to the rear part such that a reception space is defined between the rear part and the front part, a connection part, which extends from the front part and is coupled to the rear part to close lateral and lower sides of the reception space, and a magnet member provided at the rear part. Loss of the card wallet is prevented by virtue of being attached to the mobile phone. Since the upper end of a card is first exposed from the card wallet when the card is taken out of the card wallet, the card is easily taken out of the card wallet.
