产品描述 概述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. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格Tag | N-Trx | 种属 | Human | 表达系统 | E.coli | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4. | 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. | Reconstitution | Dissolve the lyophilized protein in distilled water. | Purity | Greater than 85% as determined by reducing SDS-PAGE. | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | 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. |
