(a) Two clones were available for the transcription factor PU.1 (found in some myeloid cell subsets). Both are on the same fluorophore, but only clone 7C6B05 was able to resolve a separate population. A titration was preformed, but the population was never discernible by clone 7C6B057C2C34.
(b) Here the same clone from two different companies on two similar fluorophores was evaluated on the same PBMC donor. You can see company A conjugated-antibody was able to resolve a CD3+ CRTH2+ population, however company B’s conjugated antibody was not. Increasing the concentration did not help and simply resulted in more spread in the negative.
