Mouse Bladder Tumor Antigens

Table 1 Expression of antigens defined by antibodies 3872 and 6.10 in frozen sections of tumor, as detected by immunohistology A modification of the Sternberger PAP technique (6) was used to demonstrate antigen expression in frozen sections of various tissues, as described under "Materials and Methods." The degree of staining detected was graded from (negative)through + (weakly positive) to ++++ (very strongly positive).Essentially all (>90%) carcinoma cells were stained within positive tumors, although their degree of staining varied from ++ to ++++.
