[Histonet] histology samples

From:Heather A Leba

Hello all, 

I've been doing histology for only about a year and am in the middle of a study on reproductive biology of goatfish, Mullidae, and most of my stuff has turned out well, with only minor problems. But, my question is this...does anyone know a reliable source to which I can send preserved ovaries to be embedded, sectioned, made into slides and stained with H & E?? I've been doing this myself but it would cut a lot of time out of my project if I could send them out, and unfortunately our university's histological prowess is lacking. A fellow grad student of mine said she'd sent them to Louisiana State I believe, but I cannot get a hold of her. Any suggestions would be welcomed!
