Fixation

Platelet stabilizers, as well as fixative solutions optimized for use with Beckman Coulter’s lysis product portfolio. Cell fixation is accomplished using a cross-linking agent, while permeabilization of white blood cells and lysis of red blood cells is achieved using a detergent. A denaturing agent “unmasks” proteins bound to other proteins or DNA. Beckman Coulter researchers developed the kit for use with whole blood, bone marrow or other fluids containing blood. Samples are fixed in small test tubes or deep-well microplates and the reagent is mixed with the cells. The kit can be used to study a variety of other intracellular and intranuclear antigens.

These innovative, fixation reagent kits for intracellular staining from Beckman Coulter Life Sciences, minimize sample manipulation for a streamlined workflow that delivers high quality results. Developed for use on Beckman Coulter’s Gallios and Navios series flow cytometers and compatible with all Beckman Coulter Life Sciences’ fluorochromes, the kits enable a clear focus on the cytoplasmic and nuclear compartments of the cell.
