CliniMACS® CD19 Product Line

CD19 Product Line

As a B cell lineage marker, CD19 is expressed from the early pro-B cell stage to the B cell lymphoblast stage; however, CD19 is down-regulated as B cells mature to plasma cells. The CD19 antigen is also expressed on most malignant B cells and on a subset of follicular dendritic cells.
The CliniMACS® CD19 Product Line consists of murine anti-CD19 monoclonal antibodies conjugated to superparamagnetic iron dextran particles.
One vial contains 7.5 mL sterile, non-pyrogenic solution.
The performance of the CliniMACS CD19 Product Line depends on the individual separation strategy. For information on respective capacities, refer to the CliniMACS User Manual or contact your local representative.
Please inquire about required CliniMACS System components and accessories.


The CliniMACS
System components, including Reagents, Tubing Sets, Instruments, and PBS/EDTA Buffer, are designed, manufactured and tested under a quality system certified to ISO 13485.
In the EU, the CliniMACS System components are available as CE-marked medical devices for their respective intended use, unless otherwise stated. The CliniMACS Reagents and Biotin Conjugates are intended for in vitro use only and are not designated for therapeutic use or direct infusion into patients. The CliniMACS Reagents in combination with the CliniMACS System are intended to separate human cells. Miltenyi Biotec as the manufacturer of the CliniMACS System does not give any recommendations regarding the use of separated cells for therapeutic purposes and does not make any claims regarding a clinical benefit. For the manufacturing and use of target cells in humans the national legislation and regulations - e.g., for the EU the Directive 2004/23/EC ("human tissues and cells"), or the Directive 2002/98/EC ("human blood and blood components") - must be followed. Thus, any clinical application of the target cells is exclusively within the responsibility of the user of a CliniMACS System.
In the US, the CliniMACS CD34 Reagent System, including the CliniMACS Plus Instrument, CliniMACS CD34 Reagent, CliniMACS Tubing Sets TS and LS, and the CliniMACS PBS/EDTA Buffer, is FDA approved; all other products of the CliniMACS Product Line are available for use only under an approved Investigational New Drug (IND) application or Investigational Device Exemption (IDE).
CliniMACS MicroBeads are for research use only and not for human therapeutic or diagnostic use. Unless otherwise specifically indicated, Miltenyi Biotec products and services are for research only and not for therapeutic or diagnostic use.


The CliniMACS CD19 Product Line was developed for depletion of CD19
B cells from human heterogeneous hematologic cell populations in combination with the CliniMACS System.
The depletion of CD19
cells can be performed to remove unwanted malignant or potentially EBV-infected B cells from cellular products.
The CliniMACS CD19 Reagent can also be used in combination with the CliniMACS CD3 Reagent in order to additionally remove CD3
T cells from a graft.
