产品描述 概述Recombinant Human Stem Cell Factor is produced by our Mammalian expression system and the target gene encoding Glu26-His214 is expressed with a 6His tag at the C-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 | C-6His | 种属 | Human | 表达系统 | Human cells | Accession# | P21583 | Source | Human Cells | 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, thoμgh 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 95% as determined by reducing SDS-PAGE. | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | Background | Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid, erythroid, and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors. | Biological_Activity | Measured in a cell proliferation assay using TF 1 human erythroleukemic cells. The ED50 for this effect is 1-5ng/ml. |
