Abstract

A method of purifying a biological component found in a biological sample by extracting the biological component from the biological sample. The method is performed using a microfluidic device having at least one well for receiving the biological sample and at least one channel for introducing and removing fluids. A plurality of magnetic beads having a factor with an affinity for the biological component is introduced to the well together with a suitable biological sample. The biological sample is manipulated to release the biological component in proximity to the magnetic beads which are then segregated within the well while removing the biological sample. An elution solution for the biological component is introduced to the well and the elution solution together with the biological component are withdrawn therefrom.
