FACS & Microchimerism

Does anyone have a working assay to detect microchimerism after BMT by FACS
(in the context of immunophenotyping!).  I have considered using FISH for Y
chromosome, but was unable to develop a method that allowed for
hybridization and immunophenotyping simultaneously...  Other alternatives
include CD31 polymorphism, but I'd rather not use that, and HLA-mismatched
staining, which is a pain since you have to have some many different
reagents.  Has anyone developed a IP-compatible FISH assay or a
IP-compatible VNTR assay?  Also, is anyone doing VNTR analysis on small
numbers of cells (10,000 or less)?

thanks for any information

mr
