| MDL number | MFCD00132771 |
| General description【一般描述】 | Sephadex® G-50, Medium is an often-cited gel filtration medium for desalting and buffer exchange of biomolecules > 30,000 MW. Sephadex® is prepared by crosslinking dextran with epichlorohydrin. Sephadex products differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. “Medium” indicates a large particle size for use in large-scale group separations where high flow rates and low operating pressures are required. |
| Application【应用】 | Sephadex® G-50 has been used to purify the DNA products in cycle sequencing reactions. Sephadex® G-50 is suitable for spin column purification of DNA (from contaminating small molecules) for use in hybridizations. It was used to purify PCR products prior to DNA sequencing reactions. |
