FAQ: How pure is Endoproteinase AspN? Has it been checked for nuclease activity?

The enzyme is provided in a nearly homogeneous form and may be free of nucleases but we have no data to support this. We presently have no QC test in place to qualify whether the Endoproteinase AspN is free of nuclease contamination. This product is intended to be used in Proteomic applications where generally nucleases are not an issue.
