It turns out urokinase is really expensive and hard to get. Josie and Celeste make an early morning call and find this out. Thanks so much to the folks at Sigma-Aldrich for taking on the task of finding an affordable alternate, lysozyme, in the spirit of the original experiment! Not only did Sigma-Aldrich suggest lysozyme – they donated some for our effort. Thank you very much Sigma-Aldrich!
