Two-dimensional Gel Electrophoresis01:22

Two-dimensional Gel Electrophoresis

5.9K
Two-dimensional gel electrophoresis is a high-resolution protein separation method first introduced by O' Farrell and Klose in 1975. This method involves protein separation by two dimensions, mass and charge, making it more accurate than one-dimensional gel electrophoresis.
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

SDS-PAGE

22.3K
Gel electrophoresis is a method that separates biological macromolecules like nucleic acids or proteins by forcing them to pass through a gel matrix under an electric field.
A variation of gel electrophoresis, termed  polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact...

Summary
This summary is machine-generated.

Modifying the end group of cationic polymers via atom transfer radical polymerization (ATRP) controls gel formation in water. A phosphonate anionic end group creates a homogeneous gel, unlike neutral end groups which yield low-viscosity solutions.
