Fig. 4From: Bioprocess performance analysis of novel methanol-independent promoters for recombinant protein production with Pichia pastorisEffect of dilution rate on the qp ratio and the CALB differential RTL calculated as log2 fold change relative to GAP-C values. GAP-C values were used as a control for ratio calculations. P-values (t-test) were calculated in order to determine the CALB expression significance between producer clones (* significance level P ≤ 0.05; ** significance level P ≤ 0.01)Back to article page
