| 产品介绍 |
磁性微球结构： 【性状】 本品为褐色悬浮液，分散溶剂为磷酸缓冲液（PBS）。SLC具有良好的单分散性和磁响应性。悬浮液久置会沉降，振摇、超声可重新分散磁性微球。 【产品描述】 SLC系列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响应性等特点。在磁性微球表面通过化学修饰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。 【使用注意事项】 1. SLC系列磁性微球可以耐受丙酮、甲苯、氯仿等有机溶剂。 2. 请保持pH在2-8范围内，以防止SLC磁性微球融熔变形或粘结成团。 3. 用前振摇分散，超声波有助于磁性微球的分散。 4. 使用前用PBS等溶液清洗。 【规格】 5 ml装SLC的PBS悬浮液，固含量0.5 %（w/v）（<1 μm） 5 ml装SLC的PBS悬浮液，固含量1 %（w/v）（>1 μm） 【溶剂组成】 PBS pH 7.40 叠氮化钠 0.01 % （防腐剂） 二氧化硅 磁性材料 化学修饰 特点： 1. 完全超顺磁性 2. 粒径分布均匀，单分散性更好 3. 现货供应从 0.1 μm-5.0 μm 粒径范围内的单分散磁性微球用于DNA / RNA纯化等 Magnetic microsphere structure: [Character] This product is a brown suspension, dispersion solvent is phosphate buffered saline (PBS). SLC has good monodisperse and magnetic response. Suspension, long home to be a settlement, shaking, ultrasound can be re-dispersed magnetic microspheres. [Product Description] SLC series magnetic microspheres with narrow size distribution, magnetic field and superparamagnetic settling consistent response characteristics. The magnetic surface of the microspheres by chemical modification on the combination of a number of different chemical functional groups, and antibodies specific for the protein and nucleic acid, nucleic acid purification can be used, the cell selection, immunoassay, and other fields of clinical diagnosis, the medicine, molecular Biology purification indispensable tool. [Storage] Stored at 4 ℃, Do not freeze. SLC electron micrograph of magnetic microspheres [Precautions] 1. SLC series of magnetic microspheres can be tolerated as acetone, toluene, chloroform and other organic solvents. 2 Please keep the pH in the 2-8 range, in order to prevent SLC magnetic microspheres melt deformation or bonded into a group. 3, with shaking before dispersing, ultrasonic dispersion of magnetic microspheres help. 4 before use cleaning solution such as PBS. [Specifications] 5 ml of PBS loaded SLC suspensions, solid content 0.5% (w / v) (<1 μm) 5 ml of PBS loaded SLC suspension solids content 1% (w / v) (> 1 μm) [Solvent composition] PBS pH 7.40 0.01% sodium azide (preservative) Silica Magnetic Chemically modified Features: 1 completely superparamagnetic (2) particle size distribution, better monodisperse 3 shelf from 0.1 μm-5.0 μm size range monodisperse magnetic microspheres |
