The detection of estrogen (ER) and progesterone (PR) receptors using immunohistochemical staining of formalin fixed, paraffin embedded (FFPE) tissue, has gradually replaced ligand binding assays, to become the most common method for the determination of the ER/PR status of breast tumors (Yaziji et al.
2008).
~75% to 80% of breast tumors have estrogen and/or progesterone receptors, and the presence of these receptors helps determine both the patient’s prognosis and the effectiveness of hormonal therapy (Bhargava et al.
2012).
Applications:Suitable for use in Western Blot and Immunohistochemistry.
Other applications not tested.
Recommended Dilution:Immunohistochemistry (Frozen): 1:40-1:60, the use of Zamboni's fixative is recommended
Immunohistochemistry (Paraffin): 1:40-1:80, requires antigen retrieval using heat treatment prior to staining of paraffin sections.
It is recommended to use sodium citrate buffer pH 6.0 for this purpose.
Western Blot: 1:50-1:100 for 2 hrs.
