Product Description
Picrosirius Red Stain Kit
The Picrosirius Red Stain Kit is designed for histological staining of collagen in tissue sections. Picrosirius Red binds strongly to collagen fibrils, enabling visualization of collagen-rich structures and supporting collagen morphometry workflows.
When used with polarized light microscopy, Picrosirius Red staining is commonly used to evaluate collagen fiber organization and to help differentiate collagen fiber populations (often discussed in the context of Type I vs Type III) based on birefringence appearance. The stain is also frequently used in image analysis workflows to estimate collagen content in a defined region of interest (for example, collagen area fraction), depending on the method used.
Picrosirius red-hematoxylin workflows are often used for examination of dental and connective tissue specimens in research settings, where collagen features (including dentinal tubules and Sharpey’s fibers) may be easier to visualize than with hematoxylin and eosin alone.

FAQs
Common questions about Picrosirius Red Stain Kit.
-
Picrosirius Red staining is commonly used in histology to visualize collagen in tissue sections and to support collagen morphometry and image analysis workflows.
-
Picrosirius Red binds to collagen fibrils, and under polarized light collagen can show birefringence that helps researchers assess fiber organization and collagen-rich regions. Interpretation depends on sample preparation, microscopy settings, and analysis method.
-
In many research workflows, polarized light appearance after Picrosirius Red staining is used to help differentiate collagen fiber populations often discussed as Type I vs Type III. This is an indirect method and results can be influenced by fiber thickness, packing, section thickness, and imaging conditions.
-
“Collagen area fraction” typically refers to the proportion of a selected image region that is classified as collagen-positive based on a defined staining threshold and analysis workflow. Exact values depend on how images are acquired and processed.
-
Picrosirius Red is commonly evaluated using brightfield microscopy for general staining and polarized light microscopy when birefringence-based collagen assessment is desired.
-
Many histology workflows use a counterstain (such as hematoxylin) alongside Picrosirius Red to provide additional tissue context. The best approach depends on tissue type and the study endpoint.
