Colorimetric Assay שמודד את הפעילות באופן ספציפי Granzyme B מפרקי חלבונים: הידרוליזה של הבוק-עלא-עלא-Asp-S-Bzl

We describe a simple, quantitative colorimetric assay that specifically measures the proteolytic activity of human, mouse or rat Granzyme B (GzmB). This protocol can be easily adapted for determining protease activity of other granule serine proteases by the hydrolysis of other synthetic peptide substrates with an appropriate recognition sequence.
