Ficoll 400 聚蔗糖400 CAS:26873-85-8 Storage:RT MW range………………300000-500000 Intrinsic viscosity……….17 ml/g Speci?c rotation [α]20 ….+ 56.5o Stokes radius…………..10 nm Cl- content………………< 1% 說明:Ficoll PM400, is a synthetic neutral, highly-branched hydrophilic polymer of sucrose with an average molecular weight of 400 000. It has long been used in the formation of density gradients for the separation and isolation of eukaryotic cells, organelles, and bacterial cells, as a stabilizing agent and as a separation medium for the isolation of lymphocytes. It also has applications in de?ned culture media, nucleic acid hybridization, electrophoresis, and immunological studies. The favorable osmotic, density, and viscosity characteristics of Ficoll PM400 make it an excellent choice for many applications. Because of its high molecular weight and low content of dialyzable material, Ficoll 400 does not normally penetrate biological membranes. |
注:由于Ficoll 400粘度較大,配制溶液時要緩慢將Ficoll 400加入到溶液中,并邊加入邊攪拌。
