Abstract
There has been demand for an additional method for producing antibodies. The present invention provides: a polymer-coated crosslinked alginate gel fiber in which a core layer containing a crosslinked alginate gel and either antibody-producing cells (e.g., antibody-producing CHO cells) or bioactive-substance-producing cells (e.g., MIN6 cells derived from pancreatic β cells) is coated with a cationic polymer; and a method for producing antibodies, a bioactive substance, etc., using the fiber.
