  • Description
    Columns with pre-swollen Sephadex G-25 beads for buffer exchange and desalting of protein samples.. EZ-Desalt™ Spin Desalting Column offers a convenient option to quickly desalt, buffer-exchange, or clean-up protein samples in solution. Each of the disposable, ready-to-use, spin desalting column contains 0.5 ml pre-swollen Sephadex G-25 beads, that efficiently separates proteins (or other high molecular weight components) from small molecules (salt and other small molecules such as LMW dyes etc.). Large molecules are too big to enter the pores of the beads and are excluded from Sephadex matrix and are eluted immediately after the void volume of the column, whereas small molecules are retained by the resin, with the cut-off size of about 7 kDa. The whole process takes few min. and achieves an excellent recovery of proteins (>90%), and efficient removal of the salt or unwanted small molecules.

MeSH Data
  • Name
  • Concept
    Scope note: Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts.
