At the recent ISAC meeting there was discussion of the archives that are being
established at Los Alamos for flow cytometry files. These currently include
examples of various types of data files to aid software developers.
I would like to propose that these archives be extended to include
excitation and emmision spectra of the various fluorochromes used in cytometry.
I would suggest that these be normalized to allow easy comparison and overlays
to evaluate compensation needs. I have added a possible file structure below but
I am very open to suggestions, additions, modifications etc. I would also like
some discussion on such issues of checking the calibration of
spectofluorimeters and measurement of fluors that need enzymatic processing (AM
esters). I am in the process of collecting some spectra that could be used to
start things off but contributions from others will be welcome once the format
is set. Thanks for your interest.
