Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.

A very common method for separating proteins by electrophoresis uses a discontinuous polyacrylamide gel as a support medium and sodium dodecyl sulfate (SDS) to denature the proteins. The method is called sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The most commonly used system is also called the Laemmli method after U

Several forms of polyacrylamide gel electrophoresis (PAGE) exist, and each form can provide different types of information about proteins of interest. Denaturing and reducing sodium dodecyl sulfate PAGE (SDS-PAGE) with a discontinuous buffer system is the most widely used electrophoresis technique and separates proteins primarily by mass.

1-dimensional polyacrylamide gel electrophoresis. The most common form of protein gel electrophoresis is comparative analysis of multiple samples by one-dimensional (1D) electrophoresis. Gel sizes range from 2 x 3 cm (tiny) to 15 x 18 cm (large format). The most popular size (approx. 8 x 8 cm) is usually referred to as a "mini gel".

is open to air. As polyacrylamide is very easily film-forming, when this layer is submitted to freezing it become a skin. Polyacrylamides are film forming, so when a layer is subject to freezing temperatures, a solid gel like skin is quickly formed. This skin can finally be removed from the surface, fall in the product and contaminate the emulsion

Polyacrylamide Gel Electrophoresis (PAGE) Acrylamide gels serve as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the smaller molecules travel more rapidly than larger proteins (see figure below). In most PAGE applications, the gel is mounted between two buffer chambers, and the only
