What is Ultracentrifuge? Definition of Ultracentrifuge An ultracentrifuge is an advanced centrifuge that operates at extremely high speeds to separate smaller molecules and particles based on their density. Principle of Ultracentrifuge The principle underlying the operation of an ultracentrifuge is based on the same fundamental principle as other centrifuges. It utilizes the concept of sedimentation, … Read more

What is chromatography? Chromatography Definition Chromatography is a laboratory technique used to separate, identify, and purify the components of a mixture based on their differential affinities for a stationary phase and a mobile phase. Chromatography Overview “Chromatography” is an analytical method that is used to separate the chemical mixture into its constituents in order that … Read more

What is Native Polyacrylamide Gel Electrophoresis? Principle of Native Polyacrylamide Gel Electrophoresis (PAGE) The principle of Native Polyacrylamide Gel Electrophoresis (PAGE) is based on the separation of proteins according to their net charge, size, and shape in their native structure. The technique takes advantage of the fact that most proteins carry a net negative charge … Read more
