Glycogen, 5 g, plastic
WGK 1
CAS No. [9005-79-2]
EG-Nr. 232-683-8
Stock solution: 5 mg/ml in distilled, sterile water
Working concentration: 50 µg/ml
Long-chain polysaccharide made of glucose. Most frequently used in biochemistry and as 'carrier' during precipitation of nucleic acids. Recovery of precipitated DNA is significantly enhanced by addition of 50 µg/ml glycogen; even starting from solutions with very low DNA concentrations, efficient precipitation can be performed.
Contains no nucleic acid and doesn't hinder enzymatic down-stream applications.
Glycogen contains a central protein and should not be applied if DNA is to be used in protein binding-assays following precipitation. In these cases we recommend to use our glycogen-free coprecipitants.

General information
Carbohydrates or Saccharides make up 50 % of the dry biomass of the earth and are therefore the most frequent class of biomolecules. Besides at least two hydroxy groups, they also have an aldehyde or a ketone group and can be subdivided according to the number of monomeric components in mono-, di-, oligo and polysaccharides.
Whereas mono-, di- and oligosaccharides are soluble in water, taste sweet and are therefore called as sugar, polysaccharides are hardly, or not at all, soluble in water and have a neutral taste.
Carbohydrates, together with fats and proteins make up a large percentage of nutrition. In addition to their central role as an energy source, they are also an important structural component especially in plants (e.g. Cellulose). Ribose, a monosaccaride with five carbons (C5H10O5) is an essential element of coenzymes (such as ATP, FAD and NAD) and a structural component of RNA. Desoxyribose (a ribose derivative) is a structural component of DNA.
Oligo- and polysaccharides
Oligosaccharides consist of three to nine monosaccharide units.
Polysaccharides are macromolecular substances that consist of ≥10 monosaccharide units. A distinction is made between homoglycans, which are made up of only one type of monosaccharides (e.g. starch) and heteroglycans, which consist of at least two different monomeric components (e.g. xanthan).
