Particle/cell separation device and compositions
View Patent ↗A particle/cell separation device is described which is particularly adapted for neutrophil depletion from a preparation of whole blood or platelet-rich plasma. Also described are blood and platelet rich plasma compositions produced using the device which are neutrophil-depleted.
1. A device for separation of neutrophils from platelet rich plasma comprising:
an inlet end portion comprising an inlet port for receiving a sample of platelet rich plasma;
an outlet end portion comprising at least one collection port for removing neutrophil-depleted platelet rich plasma; and
a flow path placed within an electric field comprising a tubular material in fluid communication with the inlet port and the at least collection port;
wherein the tubular material is latticed or coiled, and has a diameter of 10-100 microns; and
wherein the outlet end has a positive charge and the inlet end has a negative electrical charge.
2. The cell separation device of claim 1 , wherein the tubular material is made of plastic or silicon.
3. A blood filtering device that includes the cell separation device of claim 1 .
4. A device for producing platelet rich plasma which includes the cell separation device of claim 1 .
