DEFINITION

Classification: 435/343.1

Binds a lymphocytic or lymphocytic-like cell or component or product thereof (e.g., B cell, B-lineage bone marrow cell, null cell, natural killer cell, B-lymphoblastoid cell, B-lineage acute lymphoblastic leukemia cell, B-lymphocytic cell surface antigen, etc.):

(under subclass 343) Subject matter involving an animal cell which produces a monoclonal antibody or antigen-binding fragment thereof whose antigen-binding site(s) will combine with an integral or isolated part of a lymphocytic or lymphocytic-like cell, or with a substance shed or secreted by a lymphocytic cell or lymphocytic-like cell.

(1) Note. Lymphocytes are considered to be either B- or T-lineage cells. Null cells, K cells, and natural killer cells are considered "lymphocytic-like" cells, since they have the morphology of lymphocytes but not the antigenic markers of either B- or T-lineage cells.
