Immunoperoxidase localization of Sporothrix schenckii and Cryptococcus neoformans. Staining of tissue sections fixed in 4% formaldehyde solution and embedded in paraffin.

An indirect immunoperoxidase staining method has been successfully applied to 4% formaldehyde solution tissue sections fixed in and embedded in paraffin for the localization of Sporothrix schenckil and Cryptococcus neoformans without prior trypsinization of tissue sections. A comparison of this method with an analogous immunofluorescence staining technique has been made.
