DEAE-DEXTRAN

Details:

English name: DEAE Dextran
Molecular formula: Dextran-OCH2CH2NH+(C2H5)2C1-
CAS number: 9015-73-0
Molecular weight:~ one hundred and fifty thousand
Level: High Purity Grade
Ash：≤1.0%
Nitrogen Content：3.0～3.5
Appearance: White powder. Insoluble in ethanol, stable in neutral solutions, hydrolyzed in strong acids and at elevated temperatures, and oxidized at end groups in alkaline solutions. Easy to dissolve in water, odorless and tasteless, its solution can be sterilized by hot pressing at 10-15 ℃ for 30-45 minutes. Glucan exists in the mucus secreted by certain microorganisms during their growth process.
Purpose: Biochemical research. The cross-linked glucan anion exchanger made by linking diethylaminoethyl ion exchange groups to cross-linked glucose dissociates - OCH2CH2N (C2H5) 2 in solution. Ion exchange cross-linked glucan has a high charge density, so it has a larger total exchange capacity than ion exchange cellulose. Cross linked glucan also has a three-dimensional space network structure, so it has both ion exchange and molecular sieve functions. However, when the PH or ionic strength of the elution medium changes, it will cause a large change in the gel volume, causing gel to break, or because the gel shrinks, it will cause a large change in the solute volume, causing gel to break, or because the gel shrinks, it will cause solutes to fall into the grid and cannot come out, so it is necessary to select an appropriate ionic strength for elution
