名称:重组人ATP-binding cassette sub-family B member 5/ABCB5Protein(N-Trx);
产品说明(Description) Recombinant Human ATP-binding cassette sub-family B member 5 is produced by our E.coli expression system and the target gene encoding Ile141-Val247 is expressed with a Trx tag at the N-terminus. Accession #: Q2M3G0 Known as: ATP-binding cassette sub-family B member 5; P-glycoprotein ABCB5; ABCB5 P-gp; ABCB5; 制剂(Formulation) Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4. 质量控制(Quality Control) Purity: Greater than 85% as determined by reducing SDS-PAGE. Endotoxin: Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. 复溶(Reconstitution) Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 保存(Storage) Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. 背景(Background) ATP-binding cassette sub-family B member 5(ABCB5) is a plasma membrane-spanning protein. ABCB5 is principally expressed in physiological skin and human malignant melanoma. ABCB5 has been suggested to regulate skin progenitor cell fusion and mediate chemotherapeutic drug resistance in stem-like tumor cell subpopulations in human malignant melanoma. It is commonly over-expressed on circulating melanoma tumour cells. Furthermore, the ABCB5+ melanoma- initiating cells were demonstrated to express FLT1 (VEGFR1) receptor tyrosine kinase which was functionally required for efficient xenograft tumor formation, as demonstrated by shRNA knockdown experiments. 电泳(SDS-PAGE) FOR RESEARCH USE ONLY
