Spillover (Minimize spillover)
A single fluorochrome can be detected in more than one channel
Spectral Overlap
Correcting overlap
Compensation
Compensation is a mathematical subtraction to correct spectral overlap

Rules for choosing the right fluorochromes
“Rules” for selecting Multicolor Panel
taken from BD Biosciences
Rule 1: Choose the brightest set of fluorochromes
for your particular instrument configuration.
Rule 2: Choose fluorochromes so as to minimize the
potential for spillover.
Rule 3: Reserve the brightest fluorochromes for
“dim” antibodies, and vice versa.
Rule 4: Avoid spillover from bright cell populations into
detectors requiring high sensitivity for those
populations.
Rule 5: Take steps to avoid tandem dye degradation,
and consider its impact upon results.
