    Mouse

  • 特异性

    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.

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.

    Question

    Dear sir, madam,

    There is some literature stating that storage of tisse slides reduces antigen detection particulary for IHC and particulary for estrogen receptor. According to a recent article the main factor explaning the reduced staining intensity over time is the primary antibody used (Karlsson. Effects of long-term storage on the detection of proteins, DNA and mRNA in tissue microarray slides. J Histochem Cytochem 2011).

    Do you have any experience about this topic related to Ab288? I just ordered two.

    Thank you very much in advance.

    Best regards,

    Answer

    Thank you for your enquiry and your interest in our products.
    The effect of formalin fixation and the long-term storage on the detectability of different proteins have been studies for some time. The longer the tissues are fixed and stored in formalin, less intensive staining can be obtained due to epitope accessibility and/or protein degradation. Generally, the optimal time for formalin fixation for most stains is around 3-7 days.
    Currently, we do not have specific data/publications on ab288 regarding this issue.
    If you need any further assistance in the future, please do not hesitate to contact me.

    Answer

    Thank you for taking time to liaise with this customer to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results. Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab288. I would also appreciate if you can confirm some further details: 1.) The MCF-7 cells do express low levels of the estrogen receptor beta (http://www.ncbi.nlm.nih.gov/pubmed/10601611, https://www.abcam.com/index.html?datasheet=288&tab=abreviews&intabreviewid=7400where it has been induced) and as far as I know, the expression in keratinocytes can also be variable. Does the customer know that the samples used do express high enough levels of Estrogen Receptor beta? If not, I can suggest to use another positive control, such as mouse brain extractor PC12 cell lysate for example. Does the customer have such asample? 2.) Secondly, I can also recommend touse BSA as a blocking buffer. Indeed, changing the blockingbuffercan significantly improve the results. Please seethe western blot image on the datasheet of ab9385 for an illustration. https://www.abcam.com/index.html?datasheet=9385 (or use the following: https://www.abcam.com/index.html?datasheet=9385). 3.) I am not sure how the primary antibody incubation has been performed. I canhowever recommend to incubate the primary antibody overnight at 4 degrees Celsius. Should the suggestions not improve the results, please do let me know. In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund. I hope this information is helpful, and I thank you for your cooperation.
