| 产品介绍 |
本品为黑色悬浮液，分散溶剂为磷酸缓冲液（PBS）。四氧化三铁磁性纳米微球具有粒径分布均一，饱和磁化强度高的特点。悬浮液久置会沉降，振摇、超声可重新分散磁性微球。四氧化三铁磁性微球具有粒径分布均匀、磁场中沉降速度一致和超顺磁性等特点。由于具有超高的饱和磁化强度，适合于从高粘度的生物样品中提取基因组DNA。四氧化三铁磁性微球表面通过化学修饰可以结合上一系列不同的化学官能团及具有特异性的抗体、蛋白和核酸，可应用于核酸纯化、细胞筛选、免疫分析、临床诊断等多个领域，是医学、分子生物学研究中不可或缺的分离纯化工具。特点： 1. 超强的磁响应性 （饱和磁化率 >70 emu/g ） 2. 粒径分布均一 【使用注意事项】 1. 四氧化三铁磁性微球可以耐受丙酮、甲苯、氯仿等有机溶剂。2. 用前振摇分散，超声波有助于磁性微球的分散。3. 使用前用PBS等溶液清洗 【规格】 5ml装Fe3O4的PBS悬浮液，固含量0.5 %（w/v） 25mg装Fe3O4干粉 【溶剂组成】 PBS pH 7.40 叠氮化钠 0.01 % （防腐剂） This product is a black suspension, dispersion solvent is the phosphate buffer solution (PBS). Iron(II,III) oxide ( magnetic nanoparticles with particle size uniformity, and high saturation magnetization. Suspension placed long-term settlement, shaking, ultrasound can be re-dispersed magnetic microspheres. Iron(II,III) oxide magnetic microspheres with uniform particle size distribution, the same settling velocity in the magnetic field and superparamagnetic. Due to the ultra-high saturation magnetization, suitable for the extraction of genomic DNA in a biological sample from the high viscosity. Iron(II,III) oxide magnetic microspheres surface by chemical modification can be combined on a range of different chemical functional groups and specific antibodies, proteins and nucleic acids, can be applied to nucleic acid purification, cell-based screening, immunoassays, clinical diagnosis and other fields, medicine, molecular biology research an integral part of the separation and purification of tools. Features: (1)Super magnetic response (saturation magnetization> 70 emu / g) (2) a uniform particle size distribution [Precautions] 1.Iron(II,III) oxide magnetic microspheres can withstand acetone, toluene, chloroform and other organic solvents. 2. Shaking scattered before using,ultrasonic contribute to the dispersion of the magnetic microspheres. 3. cleaning with PBS solution before using [Specifications] 5ml package Fe3O4 in the PBS suspensions, solid content of 0.5% (w / v) The 25mg loaded Fe3O4 powder [Solvent] PBS pH 7.40 Sodium azide 0.01% (preservative) |
