Tests

Matrix Metalloproteinase 9 Measurement

The determination of the amount of matrix metalloproteinase 9 present in a sample.

For professionals

Technology

Agarose Gel Electrophoresis

A type of electrophoresis that uses a matrix of highly purified agar to separate large molecules.

Diagnostic Methods

Technology

Gel electrophoresis is a method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules by electrophoretic filtration through a gelatinous matrix. Subject to an electric field, each molecule in the sample mixture migrates through the matrix at a different rate, depending mainly on electrical charge and size, resulting in spatial separation within the matrix of each molecular species in the sample mixture. Agarose and acrylamide in a cylindrical tube or slab gel are commonly used media for electrophoresis of proteins and nucleic acids.

Diagnostic Methods

Technology

Gel Filtration Chromatography

Gel permeation or sieve chromatography that is performed on porous gels that separate solutes on the basis of size. Smaller solutes are included within the particles of the gel matrix more frequently than larger solutes, thus affecting elution rates.
