We have not validated it for this purpose, but it does label myoepithelial cells in breast tissue very nicely.  FYI - We are using BioCare's "RTU" p40 on Leica's Bond Max.

Hi everyone,
Are any labs using the monoclonal p40 antibody for myoepithelial cell staining in breast tissue? The pathologist that I work with has me testing this antibody to be used to differentiate between lung squamous and adenocarcinoma, but is also wondering if labs are using it on breast tissue as well.
