Sca-1 Antibody, anti-mouse, Biotin，130-126-949，美天旎

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 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 cells 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 marrow^1,2. 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 vitro.⁴ Furthermore, Sca-1 is expressed on stem cells in a variety of nonhematopoietic tissues, such as adult liver⁵, heart⁶, and prostate.⁷
