  • FAQ: Is your Endoproteinase AspN the same as the Endoproteinase AspN sold by other companies?

    No, it is different from all of the other Endoproteinase AspN's available on the market. They are from different strain sources, so they’re different enzymes with similar specificities. Our Endoproteinase AspN digests peptides rapidly, but digests proteins very poorly and only those less than 5 kD in size. Our Endoproteinase AspN was first characterized in 1994 by Tarentino. et. al. and is found in the MEROPS database.
