Abstract: The present invention relates to the field of chromatography and more specifically to producing protein affinity chromatography resins comprising affinity ligands based on a N-terminal fragment of a split intein, such as DnaE from Nostoc punctiforme, as well as methods for using the same. The N-terminal fragments are produced in inclusion bodies in bacterial cells.
