Simple and universally applicable methods for staining fixed cells are presented, as are methods that utilize detergents and proteolytic treatment to permeabilize cells. Additionally, supravital cell staining with Hoechst 33342, which is primarily used for sorting live cells for subsequent culturing based on DNA-content differences, is also described. Also presented are methods for staining of cell nuclei isolated from paraffin-embedded tissues, and deconvolution of DNA-content-frequency... - [Read Analysis of Cellular DNA Content by Flow Cytometry Protocol]

Ascitic fluid from B-cell-derived tumors is an extremely concentrated solution of specific antibodies. Ascitic fluid is often stored at -70ºC to prevent proteolytic degradation. - [Read Storage of Ascitic Fluid Protocol]
