  • 描述
    兔多克隆抗体to Estrogen Receptor beta - ChIP Grade
  • 特异性By Western blot, this antibody detects an ~55 kDa protein representing ER beta from Rat brain homogenate. Immunohistochemical staining of ER beta in Rat cerebellum results in cytoplasmic staining in Purkinje neurons. This antibody sufficiently supershifts Rat ER beta / ER response element (vitellogenin xenopus A2 gene).

靶标

  • 功能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.
  • 组织特异性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.
  • 序列相似性Belongs to the nuclear hormone receptor family. NR3 subfamily.
    Contains 1 nuclear receptor DNA-binding domain.
  • 结构域Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.

Anti-Estrogen Receptor beta antibody - ChIP Grade 图像

  • ab3577 staining Estrogen Receptor beta in human placental sac tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with formaldehyde, cut into 20 micron slices, blocked with 2.5% serum for 30 minutes at 25°C and antigen retrieval was by heat mediation in citrate buffer. The sample was incubated with primary antibody (1/200 in PBS) at 25°C for 90 minutes. An undiluted HRP-conjugated horse polyclonal was used as the secondary antibody.

  • Predicted band size : 59 kDa
    Observed band size : 55 kDa (why is the actual band size different from the predicted?)
