PIP Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

The androgen and prolactin responsive prolactin-inducible protein (PIP), also known as Gross cystic disease fluid protein (GCDFP-15) is expressed in benign and malignant human breast tumors and in such normal exocrine organs as sweat, salivary and lacrimal glands. The hormonally responsive PIP gene is expressed in benign and malignant breast tumor tissues and in such normal exocrine organs as sweat, salivary, and lacrimal glands. The cells within the body that produce PIP/GCDFP 15 appear to be restricted primarily to those with apocrine function. Studies have found PIP to be a highly specific and sensitive marker for breast cancer.
