Masson s trichrome

Manufactured by Keygen Biotech
Sourced in China

Masson's trichrome is a histological staining technique used to differentiate various types of tissues. It primarily stains collagen fibers blue, muscle fibers red, and nuclei black. This staining method is commonly used in pathological and histological analyses to evaluate the structural composition of tissues.

The livers removed from the mice were weighted, and then fixed in 4% paraformaldehyde for 48 h at room temperature. Then, tissues were paraffin-embedded and sectioned into 5-μm pieces, and the liver sections were stained with hematoxylin and eosin (H&E) and Masson’s trichrome (KeyGEN BioTECH, Nanjing, China) using standard protocol for microscopic examination (BX61; Olympus, Tokyo, Japan). Morphology and pathology were analyzed by two independent pathologists under blinded conditions.

Cardiac Histological Analysis: A Comprehensive Approach

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sections of hearts samples with 5 μm thick sections fixed in 4% PFA and embedded in paraffin were stained with Masson's trichrome (KeyGen, China) to detect the degree of collagen deposition, or hematoxylin and eosin (H&E, KeyGen, China) to measure cardiomyocytes cross-sectional areas, or CD31 (1:100, Cell Signaling Technology, USA) immunohistochemical staining to measure myocardial capillary density. Images of the left ventricular area of each section were obtained by microscope (Nikon, Japan). Frozen sections of hearts in O.C.T Compound (optimal cutting temperature compound, Sakura, USA) were cut at 5 μm per section and stained with wheat germ agglutinin (WGA, Sigma, USA) to measure cardiomyocytes cross-sectional areas. Fluorescence images were obtained using a Zeiss confocal microscope (Carl Zeiss, Germany). Image J Software (National Institutes of Health) was used to quantify fibrotic region and measure cardiomyocytes cross-sectional areas in each section. The percentage of fibrosis was measured as fibrosis areas/total left ventricular areas x 100%.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
