(A) Multiparameter fluorescent beads are analyzed with logarithmic acquisition and linear data array. You can apply this statistic to a particular fluorescence (I understand that this means: mean of fluorescence/cell). First, the beads measure binding of the mAb of interest via its Fc, which is determined by the affinity of the anti-Fc mAb on the beads. volume perm for fine hair 90 / 100 stars. Prepare the specimen chamber: Place your sample in the flow cytometers specimen chamber and circulate it for at least 5 minutes to ensure that the sample is evenly distributed within the chamber.
