10 protocols using masson s trichrome staining kit

1

Histological Analysis of Pulmonary Fibrosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Following sacrificing the animals, the lungs were removed and the left lung was fixed with 4% paraformaldehyde for 16 h. The tissue samples were then processed using graded alcohol, xylene and paraffin and blocked in paraffin. The paraffin-embedded sections (5 μm thick) were stained using a hematoxylin and eosin (H&E) kit (Biyuntian, Inc., Nantong, China) and a Masson’s trichrome staining kit (Nanjing Jiancheng Bioengineering Institute, Nanjing, China), according to the manufacturer’s instructions. The slides with H&E staining were examined using light microscopy (Eclipse TE2000-S; Nikon Corporation, Tokyo, Japan) and images were captured to determine the integrity of the tissue. The severity of pulmonary fibrosis in the lung sections stained for collagen with Masson’s trichrome stain was determined by a histopathologist who was blinded to the protocol design.

Mice were euthanized, the lungs were harvested, fixed in 4% neutral buffered formalin, and paraffin sections were prepared. Paraffin-embedded sections were deparaffinized as previously described (Gong et al., 2019 (link)), then stained with hematoxylin and eosin (H&E, Beyotime) to evaluate changes in lung morphology or with a Masson's trichrome staining kit (Nanjing Jiancheng) to visualize collagen in lung tissue.

The paraffin-embedded myocardial tissues were cut into 5-μm thick sections and stained with H&E (hematoxylin and eosin staining kit, Beyotime, Shanghai, China) or Masson’s trichrome staining kit (Nanjing Jiancheng Technology Co., Ltd., Nanjing, China). The discrepant areas were captured by a DMI4000B fluorescence microscope (Leica, Munich, Germany).

Evaluating Hepatic Steatosis and Fibrosis

Check if the same lab product or an alternative is used in the 5 most similar protocols
ORO staining was performed to evaluate hepatic steatosis. The ORO working solution was prepared by diluting the ORO stock solution (5 g/L in isopropanol) with distilled H2O at a ratio of 3 : 2. Liver sections were fixed in 60% isopropanol and stained with ORO working solution for 15 min. The stained lipid droplets were observed under a light microscope.
Fibrosis was assessed using Masson's trichrome staining kit (Nanjing Jiancheng Bioengineering Institute, Nanjing, China), following the manufacturer's protocol. The sections were then visualized under a light microscope.

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.
