Hi all, I've got some formalin fixed paraffin embedded mouse tissue. Any idea of something I could do to stain capillaries in these? Someone here mentioned mason's trichrome. Any thoughts are always welcome. Thanks! Sylvia Sylvia P. Poulos USDA-ARS-Animal Physiology Research Unit Athens, GA 30605 706-583-8279 706-542-0399 (fax)
