Antisera are native sera or preparations from native sera containing
specific immunoglobulin that have prophylactic or therapeutic action
when injected into persons exposed to or suffering from a disease
caused by a specific micro-organism. Antisera are prepared by
injecting antigens or venoms into healthy animals such as horses so
as to produce in them antibodies which are normally associated with
a globulin fraction serum. When a satisfactory degree of the
immunity is produced large volume of blood are withdrawn from the
animal and plasma is processed to produce specific antisera.
