商品描述
Sepadextran™ is a beaded gel filtration medium prepared by crosslinking dextran and it is supplied in its dry form. Sepadextran™-25 can be used for protein and nucleic acid purifications being the exclusion limit 5 kD for proteins and 10 bases for nucleic acids. Desalting (before IEX and after HIC or Affinity Chromatography) & buffer exchange (between different chromatography steps) are other uses.
Fine grade are for preparative separations and routine laboratory work.
