Re: TTF-1

Patti Loykasek at Phenopath Laboratories Seattle notes:

>>TTF is an abbreviation for thyroid transcription factor. TTF1 is positive 
on epithelial cells of thyroid and lung, so normal lung or thyroid would make 
a good control to work out the titer & pretreatments.<<

TTF1 has been all over the Pathology Listserv (PATHO-L) the last few days, 
with great enthusiasm. Expect you'll be hearing a lot about it.

I'll never see it - just wish more of my locum tenens clients had a high 
molecular weight cytokeratin stain for prostate biopsies!
