Keratinases

BCA Assay

Protein concentration of supernatant and cell disruption of E.coli carrying different keratinase plasmids (KerP, KerUS and KerA in different vectors) was measured with BCA Assay method (see chapter methods). The figure 1 below shows the BSA standard curve (blank corrected, arithmetic average of triplicates). Table 7 and 8 show the results of sample measurements (OD values: blank corrected, arithmetic average of triplicates). The concentrations are calculated with the calibration curve (BSA standard curve). Expectetly protein concentration is much more higher in cell disruption than in supernatants. It is also noticeable that protein concentraion of E.coli wild type is very high compared to engineered cultures. Unfortunately we do not have OD values, but we explain it by a higher amount of wild type cells after cultivation.
