Just curious if anyone has a good antibody to distinguish human tumor cells
growing in nude mice. We have an investigator who is interested in tracking
micrometastasis of human tumors growing in nude mice by immunohistochemistry
.  Use of exotic markers such as GFP will be the last resort.  I tried an
antibody to class I but some tumors are known to lose this antigen.  I would
appreciate any comments or suggestions.
