Modified technique for periodic acid-Schiff staining of glycoproteins on agarose-film electrophoretograms.
نویسندگان
چکیده
We have modified the periodic acid-Schiff staining technique for glycoproteins for use with thin agarose-film electrophoresis membranes. With this procedure, carbohydrate-rich proteins can be detected with negligible background staining and insignificant staining of nonglycoproteins such as albumin and nonglycosylated Bence Jones proteins (free light chains). On the other hand, carbohydrate-rich M components of immunoglobulins M and A in serum and in cerebrospinal fluid from patients with plasma cell dyscrasia are readily detected. The technique is two- to threefold more sensitive than Ponceau S. Glycoproteins in serum and body fluids can be determined as a routine analytical procedure.

Detecting glycogen in peripheral blood mononuclear cells with periodic acid schiff staining.
Periodic acid Schiff (PAS) staining is an immunohistochemical technique used on muscle biopsies and as a diagnostic tool for blood samples. Polysaccharides such as glycogen, glycoproteins, and glycolipids stain bright magenta making it easy to enumerate positive and negative cells within the tissue. In muscle cells PAS staining is used to determine the glycogen content in different types of mus...

A novel high-Ml glycoprotein was found in bovine milk. It was eluted in the void volume fraction ef the whey proteins by Sepharose 6B gel filtration and showed only restricted eleetrophoretic rnigration with SDS polyaerylamide g l electrophoresis (SDS-PAGE) in a cornposite geli) of 1.5% acrylamide/1% agarose. By using the lectin staining technique after the electrophoresed gel had been transfer...

Puroose: Proliferative diabetic retinopathy is assumed to develop because vasogenic factors are released from retinal areas that are ischaemic and hypoxic secondary to occlusion of the retinal vascular bed. It has been propclsed that vascular occlusion in diabetic retinopethy may be due to the deposition of periodic acid Schiff positive glycoprotein compounds in the retinal vascular walls. but ...
