agarose


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

ag·a·rose

(ag'ă-rōs),
The neutral linear polysaccharide fraction found in agar preparations, generally composed of d-galactose and altered 3,6-anhydro-l- galactose residues; used in chromatography and electrophoresis.

agarose

(ä′gə-rōs′, -rōz′, ăg′ə-)
n.
A polysaccharide obtained from agar that is the most widely used medium for gel electrophoresis procedures.

agarose

[ag′ärōs]
an essentially neutral fraction of agar used as a medium in electrophoresis, particularly for separation of serum proteins, hemoglobin variants, and lipoprotein fractions.

Agarose

Chemical A linear galactan obtained from purified agar which is used as a support (gel) for many types of electrophoresis and immunodiffusion; a typical gel contains ±1% agarose.
Molecular biology An uncharged polysaccharide (carbohydrate polymer) purified from agar which melts when heated to 100ºC and resolidifies when cooled below about 45°C, forming a matrix, which can be used for agarose gel electrophoresis.

ag·a·rose

(ag'ă-rōs)
The neutral linear polysaccharide fraction found in agar preparations; used in chromatography and electrophoresis.

agarose

more highly purified form of agar with similar uses to agar and widely used in the separation of nucleic acid fragments.
