<p>A method is provided for purifying from cells a target compound such as nucleic acid. The method comprises the following steps: 1) lysing a cell suspension to form a cell lysate containing the target compound; 2) applying the cell lysate to a filter to remove unwanted cells and cell debris; 3) contacting the filtered lysate with a solid phase matrix under conditions to bind the nucleic acid to the matrix; 4) separating the resultant filtered lysate from the matrix; and 5) eluting the target compound from the matrix. Apparatus is also provided. Complex purification procedures such as centrifugation are avoided.</p> |
