when i plot the polarization values, the curve comes noisy....but i can see a sigmoid trend, but why the curve and data points are not smooth?..is it because of plate or buffer conditions? I am using Perlin elmer optiplate 96F, buffer condition is 50mM Bis-tris and 0.005% Tween 20 and 1mM sodium azide. Instrument is Flex station3.
