Product Specific Information

Description: The monoclonal antibody STRO-1 recognizes STRO-1, a bone marrow (immature) mesenchymal cell surface protein. Pluripotent stromal cells can give rise to several lineages: osteoblasts and chondrocytes, which form bone, adipocytes or hematopoietic cells. STRO-1+ cells when co-transplanted with hematopoietic stem cells have been shown to reduce the occurrence of graft versus host disease. In addition, in vitro cultures of Stro-1+ cells along with CD34+ cells give rise to CFUs (colony forming units) composed of hematopoietic precursors, establishing a supporting role of these mesenchymal cells in blood cell development.

The STRO-1 antibody has been reported to recognize both bovine and rat Stro-1 protein.

Applications Reported: This STRO-1 antibody has been reported for use in flow cytometric analysis, immunocytochemistry, and immunohistochemical staining of frozen tissue sections.

Applications Tested: This STRO-1 antibody has been tested by immunocytochemistry on methanol-fixed MG-63 cells and can be used at less than or equal to 20 µg/mL. The STRO-1 antibody has also been tested by flow cytometry on MG-63 cells and can be used at less than or equal to 0.5 µg/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

Purity: Greater than 90%, as determined by SDS-PAGE.

Aggregation: Less than 10%, as determined by HPLC.

Filtration: 0.2 µm post-manufacturing filtered.

Target Information

STRO-1 is a cell surface antigen expressed by stromal elements in human bone marrow. STRO-1 binds to approximately 10% of bone marrow mononuclear cells, greater than 95% of which are nucleated erythroid precursors, but does not react with committed progenitor cells (colony-forming unit granulocyte-macrophage (CFU-GM), erythroid bursts (BFU-E), and mixed colonies (CFU-Mix). From bone marrow cells, the frequency of fibroblast colony forming cells (CFU-F) is enriched approximately 100-fold in the STRO-1-positive/Glycophorin A-negative population than in the STRO-1-positive/Glycophorin A-positive population. When plated under long-term BM culture conditions, STRO-1-positive cells generate adherent cell layers containing multiple stromal cell types, including adipocytes, smooth muscle cells, and fibroblastic elements. A STRO-1-positive enriched subset of marrow cells is capable of differentiating into multiple mesenchymal lineages including hematopoiesis-supportive stromal cells with a vascular smooth muscle-like phenotype, adipocytes, osteoblasts and chondrocytes. STRO-1 is a valuable antibody for the identification, isolation and functional characterization of human bone marrow stromal cell precursors.
