Usage and Biology

OmpA is a signal peptide attached to CotA coding sequence. OmpA signal peptide is supposed to help transfer CotA out of E.coli.

The enzyme activity was measured and calculated based on the weight of our sample. Formula: laccase activity (nmol/min/g) = ΔA /ε(ABTS mmolar extinction coefficient) / d * V (total volume of reaction) / V (volume of sample in the reaction, 0.025mL) / W (sample mass, g) * V (extracted liquid added, 1mL) / T (reaction time, 3 minutes) = 130 *ΔA / W.
