Product Overview
This rabbit polyclonal antibody recognizes Y-box-binding protein 1 (gene YBX1) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 35.9 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.

Samples with a confirmed band (WB): human HeLa cells, human MCF-7 cells, human Jurkat cells, human T47D cells, rat spleen tissue, mouse RAW264.7 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 confirmed staining (IHC): mouse testis tissue, rat testis tissue, human lung cancer 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 citrate buffer (pH 6).
Samples with confirmed staining (IHC): human placenta tissue.
Samples with confirmed staining (ICC/IF): A431 cells.
Samples with a confirmed signal (flow cytometry): A431 cells.
Immunogen
Synthetic peptide from the C-terminal region of human YB1. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes Y-box-binding protein 1 as secreted and also located in the cytoplasm, nucleus and cytoplasmic granule. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
