Leukocytes

Leukocyte Reduction Filter Product From Plateletpheresis (COBE© Trima™ LRS Chamber)
Plateletpheresis products collected using a COBE© Trima™ collection device and Trima Accel® software contain very few residual leukocytes due to the use of leukocyte reduction technology. During the collection process, leukocytes are trapped within an integrated chamber (LRS chamber). Following collection of the platelet product, some of the leukocytes are returned to the donor; however, approximately 1.5x109 leukocytes remain in the chamber following a single unit plateletpheresis. Following a double unit plateletpheresis, approximately 2.0x109 leukocytes remain in the chamber. Mononuclear cells comprise the majority of cells in the chamber. Key Biologics aseptically salvages the LRS chambers following plateletpheresis procedure by doubly heat-sealing the chamber’s ingress and egress tubing and separating the chamber from the tubing. A unique tracking number is adhered to the chamber to allow linkage to the collection procedure. The chambers with a small amount of connected tubing are provided en bloc to researchers.
If the customer wishes, Key Biologics will collect the residual leukocytes into a transfer bag by flushing the chamber contents with PBSS. The transfer bag is labeled with a unique tracking number and provided to researchers.
The chambers and the collected cell fractions are stored at room temperature pending shipment. In alignment with the intended use of the product and the customer’s requirements, chambers or flushed cells can be packaged and shipped on the date of collection for overnight delivery.
Products are packaged in a manner that ensures maintenance of a temperature between 20°C and 24°C during shipment unless the customer specifies an alternative method. Continuous temperature monitoring data tracking devices are available for use at the customer’s request.
