Device And Method Incorporating A Slideable Lid For Extracting A Targeted Fraction From A Sample

A method for isolating a target from a biological sample, the target being bound to solid phase substrate to form target bound solid phase substrate, comprising the steps of:

• providing the biological sample at a region of a surface of a lower plate;
• positioning an upper plate in spaced relation to the lower plate, the upper plate having a lower surface directed to the upper surface of the lower plate;
• drawing the target bound solid phase substrate toward the lower surface of the upper plate with a force;
• and
• moving at least one of the lower plate and the upper plate from a first position wherein the target bound solid phase substrate in the biological sample are drawn toward the lower surface of the upper plate to a second position wherein the target bound solid phase substrate are isolated from the biological sample.

A method for isolating a target from a biological sample, the target being bound to solid phase substrate to form target bound solid phase substrate, comprising the steps of:

• providing the biological sample at a first region of a surface of a first plate;
• depositing a fluid on a second region of the surface of the first plate;
• positioning a second plate in spaced relation to the first plate, the second plate having a hydrophobic surface directed towards the surface of the first plate;
• drawing the target bound solid phase substrate toward the surface of the second plate with a force;
• and
• moving at least one of the first plate and the second plate from a first position wherein the target bound solid phase substrate in the biological sample are drawn toward the surface of the second plate to a second position wherein the target bound solid phase substrate are isolated from the biological sample.
