Cell Lysis and Preservation Solutions
![]() | When analyzing leukocytes by flow cytometry, efficient cell lysis of erythrocytes from whole blood samples must performed prior to analysis. Life Technologies offers both Cal-Lyse™ premixed lysis solution for erythrocyte lysing and TransFix® Cellular Antigen Stabilizing Reagent for the stabilizing of leukocytes and the preservation of antigenic sites for accurate analysis by flow cytometry and other applications. |
Cal-Lyse™ and High-Yield Lysis Solutions
High-Yield Lyse is a premixed, fixative-free erythrocyte-lysis solution that can be used to help eliminate red cells from whole blood for flow cytometric analysis with minimal loss of rare blood cell populations. Using this reagent, lysis of erythrocytes is performed immediately following staining of the blood samples with fluorophore-conjugated monoclonal antibodies; there is no need for a wash step.
