Sirius Red binds to all types of collagen, whereas fast green stains non-collagenous proteins. This method has been applied to the measurement of collagen contents in various tissues.

The present study provides evidence that, as compared with Sirius Red alone or van Gieson staining, the Sirius Red/Fast Green method is the most sensitive, in terms of both qualitative and quantitative …

Digital image analysis is performed by using software to quantify total collagen and background based on specific threshold settings for the red, green, and blue channels. Background thresholds are set at …

During the heating process, prepare picro-sirius red stain solution (PSR). The recipe is as following:0.1% direct red 80 plus 0.1% fast green FCF dissolved in saturated aqueous picric acid (1.2% picric acid in …

Feb 26, 2025 · In this blog post, we will explore the fundamentals of picrosirius red staining, including its applications, step-by-step protocol, advantages, limitations, and troubleshooting tips. Additionally, …

A study by Segnani et al. (2015) provided a direct quantitative comparison of collagen staining in normal and inflamed rat colon tissue using Van Gieson, Picrosirius Red alone, and Picrosirius Red …

To the best of my knowledge, most users of picro-sirius red are doing research that exploits the enhancement by sirius red of the birefringence of collagen fibres, which is largely due to co-aligned …

This stain can be performed with or without the fast green for the demonstration of collagen. Sirius red is specific for type 1 collagen in tissues, but also some type 4 and complement under bright field.

Sirius Red and Fast Green is a dye combination used to distinguish collagen from its surrounding materials. Sirius Red specifically binds the [Gly-X-Y]n helical structure of fibrillar collagens, …

In bright-field microscopy, collagen is red on a pale-yellow background. Picrosirius red can cause appreciable de-staining of the nuclei. Under polarized light, thick collagen type I fibers appear …
