Benefits

Streck Cell Preservative is formerly known as Cyto-Chex

Cyto-Chex® Reagent Stabilizes Bone Marrow Cells and their Antigen Expression Profiles for Extended Analysis Using Flow Cytometry 

Conclusion: Cyto-Chex stabilized CD markers on the lymphocytes in bone marrow samples for up to 72 hours. The flow cytometric diagnosis is unchanged when comparing Cyto-Chex-treated bone marrow samples and K2EDTA samples. Use of Cyto-Chex greatly extends the time interval between specimen collection and analysis, offering improved patient convenience, the elimination of redraws, and a cost savings for the laboratory.
