  • Publication number: 20160289265
    Abstract: The invention relates to a method for the preparation of an application buffer for the purification of proteins by means of immobilized metal ion affinity chromatography (IMAC) under denaturing conditions, which is characterized in that a defined amount of a buffer concentrate having a defined pH value is mixed with a defined amount of a urea concentrate, whereby an application buffer having a defined pH value is provided. According to the invention, a corresponding kit is provided in addition. The components are stable in storage and by mixing produce an application buffer having a defined composition and a defined pH value. The need for pH adjustment or a new preparation is eliminated. The invention can thus be used in an automated manner and as a closed kit concept.
