背景信息 Breast cancer resistance protein (BCRP1), also known as placenta-specific ATP-binding cassette (ABC) protein (ABCP) or ABC G-subfamily member 2 (ABCG2), or mitoxantrone resistance protein (MXR), is a member of the ATP-binding cassette superfamily of drug transporters thought to be involved in multi-drug resistance in human neoplastic disease. ABCG2 is expressed in drug-resistant breast, colon and gastric cancer and fibrosarcoma cancer cell lines and in blast cells from patients with acute myeloid leukemia (AML). Normal tissues that express the ABCG2 protein include placental syncytiothrophoblasts, mammary ducts and lobules, epithelium in the large intestine and colon, venous and capillary epithelium and bile canalicular membrane of the liver. Several studies indicate that ABCG2 is also expressed in stem cells of different tissues and may be useful as a stem cell marker. ABCG2 is thought to be responsible for the ability of a population of very primitive hematopoietic and non-hematopoietic cells, the so-called SP (side population) subset, to efflux the Hoechst 33342 fluorescent dye. Semiquantitative RT-PCR results indicate that ABCG2 mRNA is expressed at higher levels in SP cells as compared to non-SP cells in human, rhesus monkey and mouse hematopoietic tissues, with the exception of erythroblasts and NK cells. In human bone marrow, ABCG2 mRNA expression is higher in phenotypically defined populations of primitive CD34+CD38- hematopoietic cells as compared to more differentiated CD34+CD38+ progenitor cells. Bcrp1 mRNA is also expressed in SP cells in murine skeletal muscle, in neural stem cell and progenitor cells and in nestin-positive pancreatic islet derived progenitor cells. Over-expression of the human ABCG2 gene by retroviral-mediated gene transfer confers the SP phenotype to mouse bone marrow cells. Bcrp1 mRNA is expressed in SP as well as non-SP fractions of mouse embryonic stem cells. This suggests that Bcrp1 protein levels may not always be reflected by mRNA levels, or that other characteristics of stem cells, for example, cell cycle status or expression of other transporters, are also involved in the SP phenotype. 产品信息 格式 Purified 控制 - MCF-7 cells

- Flow Cytometry
- Immunocytochemistry
应用说明 Immunocytochemistry:
Cell cultures fixed with 4% PFA 5-15 minutes at room temperature. Blocking with 10% NGS, 0.1% BSA in PBS with 0.3% Triton X-100 (Ginis et al., 2004).
Flow Cytometry:
1:100-1:1000 dilution from a previous lot was used.
Inhibition Assay:
A previous lot was used to inhibit ABCG2 (Watanabe, K. et al., (2004. FEBS Letters 565:6-10). See also Sarkadi, B., et al., 2004 FEBS 567:116-120,. Sarkadi reports that the detection and inhibition by 5D3 strongly depends on the actual conformation of ABCG2.
Blocking with 10% NGS, 0.1% BSA in PBS with 0.3% triton X-100 (Ginis, 2004).
Optimal working dilutions must be determined by end user.生物信息 免疫原品种 3T3 cells expressing human ABCG2 克隆 5D3 浓缩 Please refer to the Certificate of Analysis for the lot-specific concentration. 宿主 Mouse 特异性 Specifically recognizes an external epitope of the human form of ABCG2.

Entrez基因汇总 The membrane-associated protein encoded by this gene is included in the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the White subfamily. Alternatively referred to as a breast cancer resistance protein, this protein functions as a xenobiotic transporter which may play a major role in multi-drug resistance. It likely serves as a cellular defense mechanism in response to mitoxantrone and anthracycline exposure. Significant expression of this protein has been observed in the placenta, which may suggest a potential role for this molecule in placenta tissue. 基因符号 - CDw338

纯化方法 Protein A purfied UniProt编号 - Q9UNQ0
UniProt汇总 FUNCTION: SwissProt: Q9UNQ0 # 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.
