Tonbo Biosciences Flow Cytometry Perm Buffer (10X) is provided as a concentrate which, when diluted with distilled water to a 1X solution, provides best results in intracellular staining protocols for cytokines and other cytoplasmic antigens, by maintaining membrane permeabilization throughout staining and wash steps. The Flow Cytometry Perm Buffer is formulated for optimal resolution and low background when used in fluorophore-labeled antibody staining protocols, followed by flow cytometric analysis.
