WebFor immunophenotyping studies, it is always good to keep cell numbers less than 10,000/uL to have a good flow of cells besides having enough cells for the antibody. Webincorrect choice for the P factor. For the cells with velocity 9.6 ± 1.0 μm/s, setting the sampling factor 𝑃1−3=5 can ensure that the cell size is consistent with the ground truth from conventional DH. But for cells with a flow rate higher than this value, the P factor needs to take a larger value to ensure well-sampling.
