Fv- CONSTRUCTS WITH AN INFLUENCEABLE AFFINITY FOR A SUBSTANCE THAT IS TO BE LINKED

摘要

The invention relates to Fv constructs with an influenceable affinity for a substance to be linked, whereby the Fv constructs have peptides, which contain binding sites for effector molecules and which are linked to the variable regions. The invention also relates to a method for producing a single-chain Fv construct, in addition to the use of the inventive Fv construct for enriching and purifying substances.
