  • 製品の詳細

    Mouse monoclonal [BXP-21] to BCRP/ABCG2

  • 由来種

    Mouse

  • 特異性

    BXP-21 reacts with an internal epitope of BCRP/ABCG2, a 70 kD transmembrane half-transporter which is involved in Multidrug resistance. This antibody does not react with the human MDR1, MRP1 and MRP2 gene products.

  • アプリケーション

    適用あり: ICC, IHC-P, IHC-Frmore details

  • 種交差性

    交差種: Human

  • 免疫原

    Fusion protein composed of E. Coli maltose binding protein and BCRP peptide [126 amino acids, 271-396 AA of BCRP, GeneBank accession #AF098951].

  • ポジティブ･コントロール

    • IHC-P: Human breast cancer tissue. ICC/IF: MCF7 cells. Caco Cell lysate (see second reference cited).

  • 特記事項

    For the WB, please note the subcellular localization and distribution of the BCRP/ABCG2 in Normal Human Tissues: PMID:11309308

    We have received mixed feedback from customers, the antibody showed 45-50 kDa band size in A549 and Caco2 cell lines against predicted size of 72kDa. In response to data we have received we no longer guarantee this antibody for western blot. ABCG2 is a multi-pass membrane protein so for troubleshooting we would recommend heating the samples at 60-70C for 15-20 minutes instead of boiling and as this protein exists as homodimer so complete reduction of samples is highly recommended. In case of any other question please email scientific support team.

ターゲット情報

  • 機能

    Xenobiotic transporter that may play an important role in the exclusion of xenobiotics from the brain. May be involved in brain-to-blood efflux. Appears to play a major role in the multidrug resistance phenotype of several cancer cell lines. When overexpressed, the transfected cells become resistant to mitoxantrone, daunorubicin and doxorubicin, display diminished intracellular accumulation of daunorubicin, and manifest an ATP-dependent increase in the efflux of rhodamine 123.

  • 組織特異性

    Highly expressed in placenta. Low expression in small intestine, liver and colon.

  • 配列類似性

    Belongs to the ABC transporter superfamily. ABCG family. Eye pigment precursor importer (TC 3.A.1.204) subfamily.
    Contains 1 ABC transmembrane type-2 domain.
    Contains 1 ABC transporter domain.

      Immunohistochemical analysis of human breast cancer tissue, staining BCRP/ABCG2 with ab3380.

      Tissue was fixed with formaldehyde, blocked with 3% H2O2 for 5 minutes at 20°C and permeabilized with PBS-Tween; antigen retrieval was by heat mediation in a citrate buffer (pH 6). Samples were incubated with primary antibody (1/200 in PBS-Tween) for 1 hour at 20°C. A biotinylated goat anti-mouse polyclonal IgG was used as the secondary antibody.

      Cells were fixed in paraformaldehyde and permeabilized using 0.1% Triton X-100. Samples were then blocked using 10% serum for 2 hours at 25°C, then incubated with ab3380 at a 1/50 dilution for 12 hours at 4°C. A rabbit anti-mouse polyclonal conjugated to Alexa Fluor 594 was used as the secondary at a 1/50 dilution.

    Question

    Attached is my protocol. I deparaffinized 4 times in sub-x for 5min each(total of 20min). I'm really curious to know why the dapi never stained - new bottle opened on 6/21/12. thanks for your help.

    Answer

    Thank you for your reply and these additional details.

    When you write "I deparaffinized 4 times in sub-x for 5min each" I am unsure what you mean by sub-x. We recommend the following depariffinization protocol:



    1. Xylene: 2 x 3 minutes

    2. Xylene 1:1 with 100% ethanol: 3 minutes

    3. 100% ethanol: 2 x 3 minutes

    4. 95% ethanol: 3 minutes

    5. 70 % ethanol: 3 minutes

    6. 50 % ethanol: 3 minutes

    7. Running cold tap water to rinse

    Barring this issue, we can see no reason why you should be having no staining with any of these product or with a Dapi stain. Have you attempted using positive control tissues for these products?

    I look forward to your reply. Please do not hesitate to contact us if you need any more advice or information.

    Question

    I wanted to make sure those above primary antibodies will work with secondary antibody Ab6785. I stained using these antibodies & nothing worked, using the strongest dilution, paraffin sections, HIER(citrate buffer Ab643214). Nothing stained not even dapi. Could the citrate buffer completely wipe out all the cells? Primary antibodies: ab3380. ab27988, ab2462, ab9221 used in conjuction with secondary antibody: ab6785. Also stained using ab52816, ab109555 with secondary Antibody ab6717. nothing stained as well, using the strongest concentration for antibodies as directed. Primary Antibody - incubation 4C overnight Secondary Antibody - incubation 1hr, RT. I want to verfiy that the secondaries to go with these primaries. I have 6 primary antibodies with 2 secondary antibodies. All single staining.

    Answer

    Thank you for contacting us.

    I am very sorry to hear of the troubles which you have been having in IHC. You have indeed matched the corrected primary and secondary antibodies for this application. Antigen retrieval using a citrate buffer should not cause this effect. I am curious as to why Dapi,a fluorescent stain that binds strongly to A-T rich regions in DNA, would not be working for you either. Could you please send to me the details of your protocol including all sample preparation steps which you have taken? It seems possible to me that you are seeing incomplete de-paraffinizing or that you may have issues with the fixation of these tissues.

    I have included in this email our IHC-P protocol and our IHC troubleshooting guide for your review as well.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Question

    Our customer raise an inquiry about ab3380: Anti-BCRP/ABCG2 antibody. She would like to test in human/ EMSA. Would you please help her create the discount code?

    Read More
    Answer

    Thank you for contacting us. We do not accept reviews of EMSA at this time, so I am not able to offer the testing discount for this application.

    The antibody is capable of recognizing BCRP/ABCG2 in its native, 3D conformation, as suggested by the ICC and IHC data. It will probably be useful for EMSA of native samples too, but we do not guarantee this.

    I am sorry we cannot provide a discount code in this instance. I wish your customer good luck in her research.

    Answer

    Thank you for contacting us. ab3380; The ABCG2 target is expressed in tonsils, spleen, gall bladder and lungs etc so the sections of these tissues will be good positive control. You can find the complete expression information on Human Protein Atlas website; http://www.proteinatlas.org/ENSG00000118777/normal ab4372; ab87930 are spleen tissue slides ab4349 is human lung tissue slide ab105920; normal liver sections can be used; this target is expressed in normal liver. http://www.proteinatlas.org/ENSG00000165092/normal ab4348 is normal liver tissue slide. M7802; this does not seems to be Abcam product however CD44 is highly expressed in spleen, tonsils etc so the tissue sections of these will be a good positive control. http://www.proteinatlas.org/ENSG00000026508/normal I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
