說(shuō)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.
