Provided herein are novel fluorogenic and bioluminescent bacterial protease substrates that contain at least one bacterial protease cleavage site. In some embodiments, the proteases that cleave the protease substrates are bacterial proteases including those used for tissue dissociation, cell isolation, and cell detachment, such as the preparation of islet cells. Additionally, the novel protease substrates described herein may be used to assess the activity of certain bacterial proteases involved in isolating primary cells and stem cells. Methods and protease detection kits using the novel protease substrates are also provided herein.
