[Cytometry] Frozen PBMCs for TBNK

Hi Susan,
We run the IVD TBNK assay for many of our clinical studies. We always use fresh whole blood in this analysis to get the true enumeration of cells / uL of blood.  I doubt there will be a problem with the reagents staining for the T cells B cells and NK cells in PBMCs.  The only pitfall I can see would be that the assay will not be able to give you the true cells per uL  of blood due to the PBMC processing.  There is always some cell loss in the processing.  Hope this helps.

Best wishes,
