简介：
Overview
This article presents a protocol for periodic acid Schiff staining, specifically adapted for peripheral blood mononuclear cells (PBMCs) isolated from human venous blood. The technique visualizes glycogen content in these immune cells, enhancing our understanding of their polysaccharide composition.

What is periodic acid Schiff staining?
It is a histological technique used to visualize polysaccharides in tissues.
Why is glycogen visualization important?
It helps in understanding the metabolic state of immune cells.
How are PBMCs isolated?
PBMCs are isolated using density gradient centrifugation from whole blood.
What is the role of amylase in this protocol?
Amylase dissolves glycogen polymers, allowing for comparison between treated and untreated samples.
Can this protocol be used for other cell types?
While this protocol is optimized for PBMCs, it may be adapted for other cell types with similar characteristics.
