antilymphocyte serum
antilymphocyte serum n a serum containing antibodies against lymphocytes that is used for suppressing graft rejection caused by lymphocyte-controlled immune responses in organ or tissue transplant recipients

* * *

an antiserum, containing antibodies that suppress lymphocytic activity, prepared by injecting an animal with lymphocytes. ALS may be given to a patient to prevent the immune reaction that causes tissue rejection following transplantation of such organs as kidneys or of bone marrow. Administration naturally also impairs other immunity mechanisms, making infection a serious hazard.

* * *

(ALS) antiserum derived from animals that have been immunized against human lymphocytes, a powerful nonspecific immunosuppressive agent that causes destruction of circulating lymphocytes.
