Description
Human multipotent mesenchymal stromal cells (MSCs), also referred to as mesenchymal stem cells, are a rare population of adult stem cells that can be isolated from a variety of tissues.MSCs that have been isolated from bone marrow and subsequently cultured can differentiate to a variety of cell types, most notably adipocytes, osteocytes and chondrocytes.MSCs also have immunomodulatory effects in vivo and in vitro.In 2006, the International Society for Cellular Therapy (ISCT) proposed a cell surface marker panel for the minimal identification of human MSCs derived from bone marrow.Under this recommendation MSCs should be positive for CD73, CD90, and CD105, but be negative for CD34, CD45, CD11b or CD14, CD19 or CD79α, and HLA-DR.MSCs are also known to express numerous cell surface markers such as CD44, CD29, CD200, CD166, CD146 and CD271.In this kit we include the panel that was proposed by the ISCT.In addition, we designed this kit to be modular so that additional markers could be "dropped-in".Specifically, the MSC positive cocktail (FITC CD90, PerCP-Cy™5.5 CD105 and APC CD73) leaves the PE channel open to use in combination with the supplied negative MSC cocktail (PE CD45, PE CD34, PE CD11b, PE CD19 and PE HLA-DR), the included PE CD44 antibody conjugate, or a variety of other commercially available PE antibody conjugates.Multi color analysis minimizes cell numbers required for an assay and antibody cocktails facilitate a streamlined staining protocol to analyze multiple samples.Individual positive markers are included for compensation set-up.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light.Do not freeze.The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.The antibody was conjugated with PerCP-Cy5.5 under optimum conditions, and unconjugated antibody and free PerCP-Cy5.5 were removed.Storage of PerCP-Cy5.5 conjugates in unoptimized diluent is not recommended and may result in loss of signal intensity.The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed.The antibody was conjugated to APC under optimum conditions, and unconjugated antibody and free APC were removed.
Product Notices
- Accutase is a registered trademark of Innovative Cell Technologies, Inc.
- Please observe the following precautions:Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
- This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.
- PerCP-Cy5.5 is optimized for use with a single argon ion laser emitting 488-nm light. Because of the broad absorption spectrum of the tandem fluorochrome, extra care must be taken when using dual-laser cytometers, which may directly excite both PerCP and Cy5.5™. We recommend the use of cross-beam compensation during data acquisition or software compensation during data analysis.
- PerCP-Cy5.5–labelled antibodies can be used with FITC- and R-PE–labelled reagents in single-laser flow cytometers with no significant spectral overlap of PerCP-Cy5.5, FITC, and R-PE fluorescence.
