Andrea - I would like to modify your statement regarding WBC interference
with FCM retic analysis withg thiazole orange. WBCs can potentially
interfere with the retic % and immature reticulocyte fraction (IRF) only
if one does not gate out the WBC based upon there higher TO fluorescence
(approx 5-10X that of retics). See Cytometry 14:318-26, 1993, Heme/Onc
Clinics of N Amer 8:617, 1994, cytometry (CCC) 22:35-39, 1995, or
Laboratroy Hematology 2:2-8, 1996 for reviews. I highly recommend Verity
Software's ReticFit program, which simplifies FCM retic data analysis
from any instrument with regard to both elimination of WBCs and IRF
measurements. Call or email me directly if you have any other specific
questions.
