| Overview |
| The Anti-Sca-1 antibody recognizes stem cell antigen 1 (Sca-1) and is ideally suited for the analysis of mouse hematopoietic stem and progenitor cells by flow cytometry or fluorescence microscopy. Furthermore, Sca-1 is expressed on stem cells in a variety of nonhematopoietic tissues, such as adult liver5, heart6, and prostate7. |

Background information
Sca-1 (stem cell antigen-1) is a 18 kDa GPI-linked surface protein of the Ly-6 family (Ly-6A/E). The Anti-Sca-1 antibody clone D7 specifically recognizes recognizes both Ly-6E.1 and Ly-6A.2, which are gene products of the two Ly-6A/E alleles expressed in different mouse strains (Ly-6E.1: e.g. BALB/c, C3H, NZB; Ly6A.2: e.g. C57BL/6, SJL, 129, AKR).
Sca-1 is expressed on hematopoietic stem cell and progenitor cells in mouse bone marrow and one of the defining markers for so-called KSL (c-kit+ Sca-1+ Lin-) cells. Sca-1 in combination with CD105 (Endoglin) expression has been used to define long-term repopulating hematopoietic stem cells (LTR-HSCs) in mouse bone marrow1,2. In addition, Sca-1+ bone marrow cells also contain the mesenchymal stem cell fraction present. Sca-1+ cells have been shown to give rise to hepatocytes in vivo3 and neural cells in vitro4. |

| Mouse bone marrow cells were stained with Anti-Sca-1 antibodies conjugated to FITC (A), PE (B), APC (C), or biotin (D) and analyzed by flow cytometry. Cells stained with Anti-Sca-1-Biotin were additionally stained with Anti-Biotin-APC. |
