WebThe Sephadex® ion exchangers contain a cross-linked dextran matrix with functional groups. These groups are linked by stable ether linkages to the glucose units in the matrix. DEAE Sephadex can be used in ion exchange chromatography for purifying and isolating proteins. A25120-100G′s updated product number is GE17-0170-01. Sephadex is used to separate molecules by molecular weight. Sephadex is a faster alternative to dialysis (de-salting), requiring a low dilution factor (as little as 1.4:1), with high activity recoveries. Sephadex is also used for buffer exchange and the removal of small molecules during the preparation of large biomolecules, such as ampholytes, detergents, radioactive or fluorescent labels, and phenol (during DNA purification).

This exchange is utilized to separate proteins that have faintly differing charges. Like all anion exchangers, the resin carries a positive charge that interacts favorably with negative charges. The positive charge of DEAE cellulose is due to a protonated amine group. To ensure that the resin is protonated and positively charged, the chromatography should be performed at least 2 pH units below the pKa of the amine group, 10. … prostate cancer and fatigue symptomsWebIon-Exchange and Sephadex Gel Chromatography of DPS DPS-1 and DPS-2 from the four kinds of bamboo leaves, respectively, were dissolved in deionized water with a polysaccharide concentration of 15 mg/mL, the solution was loaded onto the treated DEAE-52 cellulose column (3.8 cm i.d. ×120 cm, Pharmacia, Shanghai, China) equilibrated with ... prostate cancer and fatigueWebThe DEAE cellulose is prepared by suspending 10 g of DEAE cellulose (DE 52 ion-exchange cellulose according to Whatman) in 200 mL of 0.05 N HCl, which is neutralized with 400 μE of 10 N NaOH, from which the supernatant is decanted.
