HUMAN GLIOMA ANTIGEN AND PROCESS FOR PREPARING THE SAME

摘要

The present invention provides a human glioma antigen or a method for preparing the same, which can be applied to diagnosis and therapy of glioma. A glioma antigen or a glioma antigen gene is prepared by a process comprising the steps of: total RNA is extracted from a glioma cell line and cDNA was synthesized; lambda phage cDNA library, which was constructed by infection of E. coli caused by introducing said cDNA into lambda phage vector, and the sera of glioma patients are made to react; positive clones to which antibodies in the serum reacted are detected with the use of labeled anti-IgG antibodies; screening is repeated several times for the detected positive clones; antigens are isolated from positive clones confirmed to be antibody-reactive; serum screening is conducted by using the isolated antigens, the sera of glioma patients and healthy persons.
