(immunology, of antibodies) Genetically engineered in order to express epitopes of different antigens.

(biochemistry) In the testing of cell surface antigens, a serological specificity that is poor or broad relative to other specificities and can be defined as 2 or more split antigens.(Example: HLA-B51 and HLA-B52 are split antigens of the HLA-B5 broad antigen)

(biochemistry) In the testing of cell surface antigens, an antigen that has a more refined or specific cell surface reaction relative to a broad antigen.(Example: HLA-B51 and HLA-B52 are split antigens of HLA-B5)

(immunology) Any of the human leukocyte antigens (HLAs) which are the determinants of histocompatibility

(immunology) The mechanism by which an infectious organism changes its surface proteins in favor of circumventing a host immune response.
