Product Overview
This rabbit polyclonal antibody detects Y-box-binding protein 1 (gene Ybx1) in mouse and rat samples and is validated for Western blot and flow cytometry. The predicted molecular weight is 35.7 kDa, and the supplier reports an observed band at about 50 kDa.
Y-box-binding protein 1 (YBX1) is a cold-shock domain protein that binds both DNA and RNA. It is a major component of cytoplasmic mRNPs, where it influences mRNA packaging, stability and translation, and it also takes part in splicing, DNA repair and transcription; it is often elevated in tumors and studied in cancer and stress responses.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Mouse, Rat) |
|---|---|
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Mouse) |
Samples with a confirmed band (WB): rat RH-35 cells, mouse spleen tissue, mouse testis tissue, mouse Neuro-2a 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, 30 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 a confirmed signal (flow cytometry): ANA-1 cells.
Immunogen
Synthetic peptide from the middle region of mouse YB1/Ybx1. The peptide sequence is conserved in rat.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes Y-box-binding protein 1 as secreted and also located in the cytoplasm, nucleus and cytoplasmic granule. Tissue expression noted by UniProt (mouse): Expressed in kidney glomeruli (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
