Figure 5From: Use of Ubp1 protease analog to produce recombinant human growth hormone in Escherichia coli Stability of UBPD2C protease. Stability of UBP1 protease measured every week after incubation of this enzyme at +20°C, +4°C, -4°C or -20°C. The first measurement of UBP1 protease activity incubated at +20°C followed after 3 days.Back to article page
