|Description:||ProFoldin desalting columns are designed to remove small molecules like salts, free enzyme substrates or ligands from a protein or DNA solution. After desalting, the protein or DNA sample is in a low-salt buffer composed of 10 mM Tris-HCl, pH 7.5. The columns can also be used for buffer exchange of protein or DNA samples to a desired buffer which is used to pre-equilibrate the column. The principle of desalting is size-exclusion chromatography with a molecular cut-off of 5 kDa. The residual salt concentration in the desalted solution is less than 2 % of the original salt concentration. The protein recovery yield is 98 % or higher. This product includes 50 pre-packed spin-columns. Each column is to desalt 25 ul of sample. The volume of desalted sample is 25 to 30 ul.|
