The later is caused by the spectral mismatch between the bead standard and the stained lymphocytes because of the use of the bandpass filter in the cytometer and wavelength-dependent instrument detection responses as explained below.
Sensors within the cytometer measure several parameters, including "low-angle forward scatter intensity," which is approximately proportional to cell diameter, and fluorescence intensities at several wavelengths, which allows for the study of cell components such as total DNA per cell, specific nucleotide sequences, and, by labeling with monoclonal antibodies, specific cellular proteins and other molecules.

In addition, the high-end flow cytometer market has been able to accommodate the demand for easier to use, faster and more flexible instruments, expanding product lines and generating new applications.
We discuss how MESF val ues are assigned to labeled microbeads and by extension to labeled antibodies, and how these assignments can lead to the estimate of the number of bound antibodies in flow cytometer measurements.
The researchers accomplished the unprecedented tally by combining two extremely sensitive technologies: a laser-driven flow cytometer capable of separating different types of cells with about 99 percent accuracy, and the polymerase chain reaction, which can detect extremely small quantities of specific DNA sequences such as those from HIV.
