Biological Activity
Prostate Specific Antigen Substrate (400 μM; 120-minute) is robustly hydrolyzed by enzymatically active PSA purified from human seminal plasma, but not by immunoprecipitated PSA from transfected AT2, AT6, PC3, and DU145 prostate cancer cell lines[1].
Prostate Specific Antigen Substrate can screen for proteolytic activity of immunoprecipitated PSA samples[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
