Compositions for detecting and surgically removing lymphoid tissue involved in tumor progression

摘要

Compositions are provided for detecting Tn antigen expressing-shed tumor antigen. The compositions include peptides having binding specificity for the Tn antigen; and a detector molecule comprising a peptide, according to the present invention, which is bound to a detectable label. The compositions may be used in a method to detect lymphoid tissues containing shed tumor antigen expressing the Tn antigen.
