Fig. 9From: Development of a silicon limitation inducible expression system for recombinant protein production in the centric diatoms Thalassiosira pseudonana and Cyclotella cryptica Productivity of recombinant protein expressed in T. pseudonana (a) and C. cryptica (b). eGFP was expressed under respective SIT1 control elements and monitored eGFP production under Si starvation by imaging flowcytometry. eGFP was measured with a 488-nm laser with 50 mW power output (a) and 100 mW power output after blocking saturation with neutral density filter 1.0 (b). Error bars represent standard errors of mean (SEM), n = 20,000Back to article page
