Cell Analysis and Reagents

Standardize and simplify multisite, longitudinal studies

The Custom Technology Team offers lyophilized products for flow cytometry, including reagents and control cells. Designed for specific experiment requirements, lyophilized reagents in pre-aliquoted formats can reduce variability between experiments, making these reagents ideal choices for multisite or longitudinal studies. Lyophilized reagents also have an extended shelf life compared to liquid reagents. In addition, researchers can easily incorporate lyophilized reagents into automated workflow processes, providing greater consistency and improved lab efficiency.

Researchers simply add sample—cells, blood, or other liquids—to rehydrate the biomolecules, and immediately begin experimental analysis. Lyophilized products can be packaged in many formats such as tubes, plates, and single vials.


Function equivalent to liquid reagents

Studies have also demonstrated that lyophilized reagents retain functionality equivalent to liquid reagents. Using standard protocols for antigen-specific activation of peripheral blood lymphocytes, and assessment of response using cytokine flow cytometry, a strong correlation in activity was found between lyophilized antibody cocktails with liquid cocktails.

Lyophilized cells as controls

Lyophilized cells as controls

Lyophilized cells are excellent as staining, instrument setup, or gating controls. In this experiment, freshly fixed, permeabilized, and stained cells were compared to lyophilized cells that were stained with conjugates to CD69 and IFN-γ (left and middle). Freshly prepared cells were also compared to cells that were stained and then lyophilized. There was virtually no difference in signal intensity or cellular events between these three preparations.
