pS2 / pNR-2 / Trefoil Factor 1 (Estrogen-Regulated Protein); Clone TFF1/1091 (Concentrate)
Immunogen: A synthetic peptide from the C-terminus of human TFF1 protein.
Isotype: IgG1, kappa
Species Reactivity: Human and Monkey. Others not known.
Positive Control: Spent medium of MCF-7 cells, treated with estrogen. Normal stomach. About 60% of breast carcinomas are positive for pS2, especially those that are also positive for estrogen and/or progesterone receptor.
Specificity: This antibody recognizes a polypeptide of 6.5kDa, identified as pS2 estrogen-regulated protein. Its epitope is located in the C-terminus of the human pS2 protein.
