Table 1 IHC staining results for 27.B1 and 27.F7 in various breast lesions.

From: Native human autoantibodies targeting GIPC1 identify differential expression in malignant tumors of the breast and ovary

Tumor type Positive cases/total cases
  27.B1 27.F7
Hyperplasia 0/4 0/4
Fibroadenoma 0/4 0/4
LCIS (Lobular carcinoma in situ) 0/4 0/4
DCIS (Ductal carcinoma in situ) 0/4 0/4
ILS (Invasive lobular carcinoma) 9/10 (90%) 8/15 (53%)
IDC (Invasive ductal carcinoma) 24/25 (96%) 11/23 (48%)
  1. Table 1 summarizes the results obtained from the immunohistochemistry of the breast lesions and illustrates the difference in staining percentage (positive cases out of the total number of samples studied) between different tumor types, implying differential incidence of GIPC1 enhanced expression.
