Abstract

The invention concerns a method for the purification of a target substance from a biological sample by immobilizing the target substance on a solid phase by means of a high affinity binding pair and subsequently eluting it by adding a partner of the binding pair in a free form. In addition reagent kits for carrying out the method are disclosed.
