Fig. 6From: A temperature dependent pilin promoter for production of thermostable enzymes in Thermus thermophilusPurification of MtlD from T. kivui produced in T. thermophilus. The enzyme was purified by Ni-NTA (elution with 300 mM imidazole) and analyzed on a 12% SDS gel. The protein was stained with Coomassie brilliant blue R-250 (A). Western blot analysis of the fractions obtained during purification of MtlD-his. Western blot analysis was performed using the penta-his antibody (1:1000 dilution) (B). The white arrow indicates MtlD-his.Back to article page
