BCA Assay Results

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 picture 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).
