The difference between he and pas stains can be confusing for those who are unfamiliar with the two methods of staining tissue samples. This blog post will explain the main differences between the two staining techniques, including the types of stains used, the purpose of each stain, and the results of both stains. We will also discuss how to choose the correct stain for your needs.

Overview of he and pas stain
The difference between Hematoxylin and Eosin (HE) stain and Periodic Acid-Schiff (PAS) stain lies in the components used in each staining method. HE stain is a two-step process using hematoxylin as the primary dye and eosin as the counterstain. The hematoxylin stains the nuclei of cells blue and the eosin stains the cytoplasm and other cell organelles pink.
The hematoxylin stains the nuclei of cells blue and the eosin stains the cytoplasm and other cell organelles pink. The PAS stain is a single-step process that uses Periodic Acid, Schiff’s reagent and a counterstain. This stain is used to identify and differentiate between carbohydrates, proteins, and lipids.
PAS stains carbohydrates and mucins (glycoproteins) pink and proteins and lipids blue. Therefore, by comparing the two stains, it is easy to see that HE stain is used to differentiate between cell organelles and PAS stain is used to differentiate between carbohydrates, proteins, and lipids.
Benefits of using he and pas stain
The use of HE and PAS stains are important tools to help medical professionals diagnose diseases and analyze tissue samples. While both stains are used to identify differences in cellular components, they each have their own unique characteristics. HE staining, or Hematoxylin-Eosin staining, is a commonly used histologic technique that uses two dyes to color and differentiate the various components of cells and tissues.
HE staining, or Hematoxylin-Eosin staining, is a commonly used histologic technique that uses two dyes to color and differentiate the various components of cells and tissues. The dyes are usually a combination of hematoxylin, which stains the nucleus blue, and eosin, which stains the cytoplasm pink. PAS staining, or Periodic Acid-Schiff staining, is another common histologic stain that utilizes a reagent to identify carbohydrates and mucosubstances in tissue.
The process of PAS staining involves the chromogenic reaction of Schiff’s reagent with carbohydrates, which results in a reddish-purple color. Both stains are important for a variety of diagnostic purposes and can help medical professionals accurately identify and diagnose diseases.
Comparison of he and pas stain
He and PAS stain are two distinct staining techniques used in histology and pathology. Both are used to highlight important components of a tissue sample, allowing for a more detailed analysis. The main difference between the two is that He staining uses a special stain that selectively binds to proteins, while PAS staining uses a combination of dyes and enzymes to detect carbohydrates, mucins, and glycoproteins.
He staining can be used to identify structures such as fibrous proteins and cell nuclei, while PAS staining is more effective at highlighting the presence of mucus, glycogen, and other glycoproteins. Ultimately, both staining methods are incredibly useful and can provide a wealth of information about a tissue sample.
Common applications for he and pas stain
The difference between HE and PAS stains is one of the most common questions for anyone looking to diagnose diseases in tissue samples. HE (Hematoxylin and Eosin) stain is the most commonly used histological stain, used to identify cell and tissue structures. This type of stain is used to visualize the nucleus and cytoplasm of cells and has been used for decades.
This type of stain is used to visualize the nucleus and cytoplasm of cells and has been used for decades. PAS (Periodic Acid-Schiff) stain is a histological stain that is used to identify the presence of carbohydrates and mucins in tissues. This type of stain is used to differentiate between healthy and diseased tissues, as well as to identify microorganisms.
Both HE and PAS stains are important tools for histological diagnosis and both can help medical professionals make more accurate diagnoses and treatment decisions.
Pros and cons of he and pas stain
When it comes to medical diagnosis, two of the most commonly used stains are hematoxylin and eosin (H&E) and periodic acid–Schiff (PAS). While both are used to color and identify different components of a tissue specimen, they have different pros and cons that make them suitable for different types of tests. H&E is the most commonly used stain in histology, and is used to color and differentiate between different components of a specimen.
It is used to identify cell nuclei, connective tissue, and other structures. The major advantage of H&E is that it is a universal stain, meaning it can be used to stain virtually any type of tissue.
Additionally, it is relatively inexpensive and easy to use. However, its main disadvantage is that it is not very sensitive.
This means that it may not reveal certain features of a sample that can be detected with other stains. On the other hand, PAS is a more specific stain that is used to detect carbohydrates and glycoproteins. It is more sensitive than H&E, meaning that it can detect features that H&E cannot, such as mucin and glycogen.
However, it is more expensive and complicated to use, and it is not a universal stain, meaning that it can only be used for certain types of tissues. To summarize, H&E is a universal stain that is relatively inexpensive and easy to use, but it is not very sensitive. PAS is a more specific stain that is more sensitive, but it is more expensive and complicated to use. Therefore, when deciding which stain to use, it is important to consider the type of specimen, the features that need to be detected, and the cost of the stain.
Conclusion
In conclusion, there is a significant difference between he and pas stain. He stain is a simple staining technique that uses two basic dyes to distinguish between different types of cells and structures within a sample.
The eosin dye binds to the cytoplasm and gives it a pink color. The contrast between the blue and pink helps to distinguish between different cell types and structures.
Pas stain, on the other hand, is a more complex staining technique that uses a combination of dyes to differentiate between different types of carbohydrates. The dyes used in Pas stain are malachite green, which binds to acidic polysaccharides, and safranin, which binds to neutral polysaccharides. Pas stain also uses a mordant, which helps to intensify the colors.
Pas stain also uses a mordant, which helps to intensify the colors. This helps to further differentiate between different types of carbohydrates. Both he and Pas stains are important tools in microscopic analysis, and each has its own distinct advantages.
