PROCEDURE: 1 Deparaffinize and hydrate to distilled water 2 Warm the diastase solution in the microwave for 20 seconds 3 Place the slide labeled \"PAS/D\" in the warm diastase solution and into the waterbath for 15 minutes do not over digest 4 Rinse in running tap water rinse in distilled 5 |
How PAs is performed in a laboratory?
PAS is performed in the laboratory for histological studies. The periodic acid of the stain reacts with carbohydrates in an oxidative process. In this process, the polysaccharide and the periodic acid reaction form an oxidized compound- aldehyde.
What is PAS reagent used for?
The PAS reaction in tissue sections is useful for the demonstration of mucopolysaccharides. The Diastase (α-amylase) digestion pro ce dure, followed by the PAS stain is useful as an aid in the diagnosis of glycogen storage disease. Periodic Acid Schiff (PAS) reagents are for ‘‘In Vitro Di ag nos tic Use’’.
What is periodic acid-Schiff staining?
Periodic acid-Schiff (PAS) is a staining technique for demonstrating the carbohydrates and fungal cell wall components. PAS can detect the presence of glycogen, polysaccharides, and mucin in the tissue that is either formalin-fixed, paraffin-embedded, or frozen tissue sections. PAS is performed in the laboratory for histological studies.
Principle of Periodic Acid- Schiff (PAS) Staining
The periodic acid of the stain reacts with carbohydrates in an oxidative process. In this process, the polysaccharide and the periodic acid reaction form an oxidized compound- aldehyde. Now, the aldehyde reacts with the Schiff reagent, which gives the purple-magenta color. Similarly, the appearance of the pink color suggests the presence of intrace
Solutions and Reagents
0.5% Periodic Acid Solution 1. Periodic acid crystals-0.5 g 2. Distilled water-100 ml To prepare 0.5% periodic acid solution mix 0.5 g periodic acid crystals in 100 ml distilled water. Schiff’s reagent Dissolve 5 g basic fuchsin in 900 ml boiled water. Once it is cools to 50°C add 100 ml 1M HCl to the mixture. Again add 10 g of K2S2O5once the mixture cools down to 25°C. After completely mixing, shake the solution for 3 minutes and let it incubate for 24 hours in a dark room. After incubation, add 5 g of activated charcoal to the mixture. Then shake the solution for 3 minutes and filter. The refiltration and retreatment of the solution are necessary if the solution is not crystal clear. Stor
Procedure For Periodic Acid-Schiff (PAS) Staining
Firstly remove the paraffin from the tissue sections by washing in distilled water.Then, place the tissue in 0.5% periodic acid solution for 5 minutes. It oxidizes the tissue.After that, rinse the tissue properly in distilled water.Then, cover it with Schiff’s reagent for 5-15 minutes which turns into light pink. microbeonline.com
