"CliniMACS® PBS/EDTA Buffer is a single-use, sterile, isotonic buffer solution used as part of the CliniMACS CD34 Reagent System. The CliniMACS® CD34 Reagent System is an in vitro medical device system used to select and enrich CD34+ cells from HPC, Apheresis while passively depleting other cells, such as CD3+ T cells, which cause graft versus host disease. The system is based on ""magnetically-activated cell sorting"" (MACS) employing antibodies conjugated to iron-containing particles that can be attracted to a magnetic field (referred to as “magnetic labeling”). Using the specificity of anti-CD34 antibody interaction with cell surface CD34 antigen found on hematopoietic progenitor cells, the system enriches CD34+ cells from HPC, Apheresis by passing the antibody-labeled cell suspension through a separation column with a strong magnetic gradient. The separation column retains the magnetically labeled CD34+ target cells while unlabeled cells flow through and are collected in the Negative Fraction Bag. Several automated washing steps are performed, disposing most of the liquid into the Buffer Waste Bag. The magnetically-selected CD34+ cells are released from the separation column when the magnet is disengaged, removing the magnetic field, and the target CD34+ cells are eluted into the Cell Collection Bag."
A sterile buffered aqueous salt solution that is a component of a magnetic cell separation system intended to be used during the magnetic separation of target cell types or subpopulations from heterogeneous human cell preparations. The device is intended for the priming of the separation system as well as the washing and elution of separated cells and to prevent cell aggregation and adherence. It is supplied in a container (e.g., polypropylene bag) and is not for direct intravenous (IV) infusion. This is a single-use device.
