Licensing factor is necessary for initiation of replication at each origin. Licensing factor is present in the nucleus prior to replication, but is removed, inactivated, or destroyed by replication. Initiation of another replication cycle becomes possible only after licensing factor reenters the nucleus after mitosis.

Flow cytometry or FACS is the sine qua non (without which, nothing) of the modern immunologist’s toolbox.

Flow cytometry is based on light scattering and fluorescence 

Forward light scattering detect shape and side scattering detects granularity and complexity of the cell
