- You want to understand how the density of P-selectin in blood vessel walls affects the rolling interactions of neutrophils when they are subjected to hydrodynamic drag forces in the blood. You introduce P-selectin into a synthetic lipid bilayer and attach it to a glass slide mounted in a flow chamber. This arrangement allows you to measure neutrophil attachment at different densities of P-selectin and at different flow rates. At high densities, from 30 to 400 P-selectin molecules per µm², the neutrophils attached to the membrane and rolled very slowly and jerkily in the direction of the flow (see cell 1 in the figure). At the same flow rate, but at a density of 15 P-selectins per µm², the neutrophils behaved differently: they either moved at the flow rate of the medium or were transiently tethered-horizontal lines marked by t-before moving again (cell 2 in the figure). Neutrophils showed this same behavior at a density of 1 P-selectins per μm² and half the flow rate: moving at the flow…a) Calculate the weight (in gram/ml) of tumour cells in each vial.
