Yields of 24 purified recombinant fusion proteins originated from 3 different gene designs. a Virtual gel showing the expression levels of 24 recombinant peptides obtained from gene design A, B and C that were purified through IMAC and evaluated using the Labchip GXII (Caliper, USA). b Comparison of expression levels of variant A (blue), variant B (orange) and variant C (grey) of the 24 recombinant peptides. On the right are representations of the means for high, medium and low expressing variants calculated for the 16 fusion peptides produced at higher yields. Means without a common letter differ at P < 0.01
