The principle and Procedure of Polyacrylamide Gel
SDS-PAGE (sodium dodecyl sulfate – polyacrylamide gel electrophoresis) is a technique used to separate the proteins according to their masses.. Separation of macromolecules under the influence of the charge is called electrophoresis.The gel used in SDA-PAGE is polyacrylamide and agent which is used to linearize the proteins is SDS. Hence the name SDS-PAGE.
Polyacrylamide Gel. PA gels provide a variety of advantages including linear elastic material properties, reproducible rigidity, excellent optical qualities, capacity to covalently attach ECM molecules to an otherwise nonadhesive surface, and a porous nature to permit penetration of media and nutrients (Wang & Pelham, 1998).

Polyacrylamide Gel Electrophoresis
Polyacrylamide gel electrophoresis (PAGE) analysis can be conveniently applied to analyze the molecular weight of sulfated GAGs. Gels on which GAGs have been fractionated can be visualized with Alcian Blue with or without silver staining and the bands can be scanned and digitized. The average MW of a GAG is then calculated based on a mixture of HP-derived oligosaccharide standards prepared

Polyacrylamide Gel Electrophoresis (PAGE
Principle of Polyacrylamide Gel Electrophoresis (PAGE) SDS-PAGE (Polyacrylamide Gel Electrophoresis), is an analytical method used to separate components of a protein mixture based on their size. The technique is based upon the principle that a charged molecule will migrate in an electric field towards an electrode with opposite sign.

Studies on Protein Extraction from Caragana korshinskii
Abstract. Caragana korhinskii Kom is a desert shrub which belongs to genus Caragana. In this work, protein extraction from C. Korshinskii Kom using acetone precipitation method was investigated. Orthogonal experiments showed that the optimal extraction conditions were as follows: ratio of extraction buffer to tissue pounder 20:1, extraction time 7 h, ratio of acetone to supernatant 3.5:1.
