Abstract

PURPOSE: To permit catch and gathering of leucocytes by simple operation and at high purity and collecting rate in a short period by using a filter for catching and gathering leucocytes.
CONSTITUTION: A porous filter with fine holes with an average caliber of 5W20μm is used and the fine holes 1 are perforated at random and penetrated from the surface of a porous structure 2 to the other side. As to the material of the porous filter, any one will be acceptable if it is hard to damage blood corpulses. However, vesicants such as synthetic rubber, synthetic resins make it easy to adjust the caliber of the holes. The filter for catching and gathering leucocytes is formed by accommodating such a porous filter 6 in a container 5 which has an entrance 3 and an exit 4. The leucocytes are gathered with high purity and collecting rate by collecting the leucocytes which were caught in the filter 6 by a proper method.
