I use porcine pancreatic elastase to induce emphysema in mice. I have one vial of elastase that was diluted in PBS and frozen, left over from my previous experiment. How can I evaluate in vitro if it still active and viable?
Hi Carolina, I agree with Theo that there a lot of small substrates and proteinaceous elastase substrates available commercially.
