Fig. 6From: High cell density fed-batch production of insecticidal recombinant ribotoxin hirsutellin A from Pichia pastorisMTT assay of Sf9 cell proliferation. The growth of Sf9 cells was analysed at the given concentrations of rHtA in 96-well plates. The X-axis shows the absorbance at 570 nm, and the Y-axis shows the final rHtA concentration added to the culture medium. Data represent the mean ± standard deviation of triplicate experimentsBack to article page
