Product Overview
This rabbit polyclonal antibody targets lymphocyte antigen 6A-2/6E-1 (gene Ly6a) in mouse samples and is validated for flow cytometry, IHC and Western blot. The predicted molecular weight is 14.4 kDa, and the supplier reports an observed band at about 14 kDa.
In mouse, Ly6A (Sca-1, stem cell antigen-1) is a GPI-anchored cell-surface protein of the Ly6 family. It is expressed on hematopoietic stem and progenitor cells and on activated lymphocytes and has been implicated in T-cell activation; Sca-1 is widely used, together with lineage markers and c-Kit, to identify mouse hematopoietic stem cells.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Mouse) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Mouse) |
Samples with a confirmed band (WB): mouse HEPA1–6 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): mouse spleen tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with a confirmed signal (flow cytometry): Hepa1–6 cells.
Immunogen
Synthetic peptide from the middle region of mouse sca1/Ly6A/E.
Reactivity Notes
The supplier lists reactivity with mouse. UniProt places lymphocyte antigen 6A-2/6E-1 in the cell membrane. Tissue expression noted by UniProt (mouse): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
