Evaluation:
Calculate the average and standard deviation for each Omnibead concentration.
Perform a blank reduction by subtracting the average signal of the blanks wells
from the average signal of each Omnibead concentration.
Plot the average blank-corrected values against the final Omnibead
concentrations in a XY scatter diagram. Add a linear trend line with intercept set
to 0 and solve the trend line equation (
y = kx
) using the 3-fold standard deviation
of the blank as y.

Extrapolate the detection limit [ng/ml] by using the 3-fold standard deviation of the
blank as y.
