[Histonet] p40 staining for breast myoepithelial cells

[Taylor, Jean]

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.

Thanks,
