In compliance with regulations, the DeGowin Blood Center routinely uses leukocyte depletion filters, also called Leukocyte Reduction System (LRS) cones, to eliminate the contaminating leukocytes from blood products, such as red blood cells, at the point of collection. These LRS cones are a source of viable human white blood cells that can be used in research applications and are available from the DeGowin Blood Center free of charge. Below is a list of links to articles describing the characteristics and use of the cells obtained from the leukocyte reduction filters.
Please contact Paula Dayton at 356-0524 with technical questions regarding the LRS cones or Julie Happel at 356-4149 regarding the process for obtaining the LRS cones.
