  • Patent number: 11008566
    Abstract: The present invention relates to a method for obtaining an antibody from an avian B cell antibody library, comprising the following steps (a) to (d): (a) a step of allowing an avian B cell antibody library to come into contact with an antigen in the presence of a calcineurin inhibitor and avian serum, (b) a step of selecting avian B cells that bind to the antigen in the step (a), (c) a step of culturing the avian B cells selected in the step (b) in the presence of a calcineurin inhibitor and avian serum, and (d) a step of obtaining the avian B cells obtained through the step (c) and/or an antibody expressed by the avian B cells.
