Scientific Data Images for Mouse Sca-1/Ly6 Antibody

Sca-1/Ly6 antibody in Mouse Splenocytes by Immunocytochemistry (ICC).

Sca-1/Ly6 in Mouse Splenocytes.

Sca-1/Ly6 was detected in immersion fixed mouse splenocytes using 10 µg/mL Goat Anti-Mouse Sca-1/Ly6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1226) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

Detection of Mouse Sca-1/Ly6 by Western Blot

Detection of Mouse Sca-1/Ly6 by Western Blot

Sca1, a marker of mammary stem/progenitor cells, is increased in DNIIR and Wnt5a-/- glands. mRNA and protein were extracted from several wild type (WT) and MT-DNIIR (DNIIR) mice. (a) Sca1 mRNA levels were determined by semi-quantitative RT-PCR and (b) protein levels were determined by western blot. Sca1 levels were increased in DNIIR glands relative to controls. (c) Sca1 protein levels were determined in WT and Wnt5a null (-/-) glands using western blot analysis. Sca1 levels were increased in Wnt5a-null tissue relative to controls. 18S and beta-Tubulin ( beta-Tub) were used as normalisation controls. DNIIR = dominant-negative transforming growth factor-beta type II receptor; RT-PCR = reverse transcripase polymerase chain reaction; Wnt = Wingless-related protein family.

Background: Sca-1/Ly6

This antibody reacts with Sca-1, an 18 kDa phosphatidylinositol-anchored protein that is a member of the lymphocyte antigen 6 (Ly-6) family (1). Sca-1 is encoded by the strain-specific Ly-6 E/A allelic gene. Its expression on multipotent hematopoietic stem cells (HSC) has been used as a marker of HSC in mice of both Ly‑6 haplotypes (2, 3). This antibody is frequently used in combination with lineage depletion antibodies to identify and isolate murine HSC. Sca-1-positive HSC can be found in the adult bone marrow, fetal liver and mobilized peripheral blood and spleen in the adult animal (2‑7). However, Sca-1 has also been discovered in several non‑hematopoietic tissues (1) and can be used to enrich progenitor cell populations other than HSC (8). It is suggested that Sca-1 could be involved in regulating both B and T cell activation (9‑12).
