  • High performance liquid chromatography mobile phase
    Patent number: 4909941
    Abstract: There is described a mobile phase for use in the purification of proteins using reversed phase HPLC on a preparative scale. The mobile phase is an aqueous solution containing 0.005 to 1M of a physiologicially acceptable acid of the general formula YCOOH where Y is a polar electron withdrawing group capable of hydrogen bonding silanol groups. The solution also contains up to 95% by volume of a physilogically acceptable organic solvent. A preparative method of purifying proteins such as HSA or BSA and recombinant deoxyribonucleic proteins using reversed phased PHLC is also described.
