製品の詳細Mouse monoclonal [14C8] to Estrogen Receptor beta
特異性14C8 is specific for human ER-beta. The antibody has been tested in WB against recombinant protein. It has not yet been tested in our laboratory using any cell lysates and several publications suggest it can give weak bands in breast tumour extracts lysate. Strong Erb staining in epithelial cell nuclei. Occasional weak to moderate staining is seen in surrounding stromal and endothelial cell nuclei. Sporadic light cytoplasmic staining is sometimes observed. We have also successfully detected ERb in colon and ovarian tumors using the same antibody.

機能Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform beta-cx lacks ligand binding ability and has no or only very low ere binding activity resulting in the loss of ligand-dependent transactivation ability. DNA-binding by ESR1 and ESR2 is rapidly lost at 37 degrees Celsius in the absence of ligand while in the presence of 17 beta-estradiol and 4-hydroxy-tamoxifen loss in DNA-binding at elevated temperature is more gradual.
組織特異性Isoform beta-1 is expressed in testis and ovary, and at a lower level in heart, brain, placenta, liver, skeletal muscle, spleen, thymus, prostate, colon, bone marrow, mammary gland and uterus. Also found in uterine bone, breast, and ovarian tumor cell lines, but not in colon and liver tumors. Isoform beta-2 is expressed in spleen, thymus, testis and ovary and at a lower level in skeletal muscle, prostate, colon, small intestine, leukocytes, bone marrow, mammary gland and uterus. Isoform beta-3 is found in testis. Isoform beta-4 is expressed in testis, and at a lower level in spleen, thymus, ovary, mammary gland and uterus. Isoform beta-5 is expressed in testis, placenta, skeletal muscle, spleen and leukocytes, and at a lower level in heart, lung, liver, kidney, pancreas, thymus, prostate, colon, small intestine, bone marrow, mammary gland and uterus. Not expressed in brain.

ab288 staining Estrogen Receptor beta in infiltrating lobular carcinoma of the human breast tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde. Endogenous peroxidase blocking was with 3% H2O2 at room temperature for 30 minutes. Blocking with 1.5% goat serum (dilute goat serum by 1xPBS), at room temperature for 30min; antigen retrieval was by heat mediation in a citrate buffer, pH 6.0, 15min (Cuisinart Electric Pressure Cooker #EPC-1200, choose "high pressure"). Samples were incubated with primary antibody (1/100) for overnight at 4°C. An ABC HRP Kit Mouse IgG) was used as the secondary antibody (1/200), room temperature for 30min. Washed twice for 5 minutes using PBS. DAB was used as a substrate.
