Elastica van Gieson-picro-fuchsin staining
The stable connective tissue staining for the differential analysis of nuclei, muscle and elastic fibres
2
Elastica van Gieson-picro-fuchsin staining
An overview staing using 3 different dyes Resorcin-Fuchsin: - elastic fibers Weigert‘s iron hematoxylin: - permanent nuclei stain Van-Gieson‘s picro-fuchsin: - connection tissue

Elastica van Gieson-picro-fuchsin staining
Dyeing results on standard tissues: nuclei: brown-black connection tissue: red elastic fibres: black musculature: yellow cytoplasma: yellow neuroglia: yellow-orange mucus, amyloid, colloid, hyalin: yellow to red Dyeing results on sponge tissues: nuclei: purple-black background tissue: pink elastic fibres (spongin): purple the stain reacts different on sponge tissue
