Product Overview
This rabbit polyclonal antibody targets galectin-1 (gene LGALS1) in human, mouse and rat samples and is validated for ELISA, flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 14.7 kDa, and the supplier reports an observed band at about 15 kDa.
Galectin-1 (LGALS1) is a small β-galactoside-binding lectin that is secreted and found both inside and outside cells. By cross-linking glycoproteins on the cell surface, it regulates cell adhesion, proliferation and apoptosis, and it strongly dampens T-cell responses, including by inducing apoptosis of activated T cells. Galectin-1 is studied in immune regulation, angiogenesis and tumor immune evasion.

Samples with a confirmed band (WB): human HeLa cells, human A549 cells, human A375 cells, human MCF-7 cells, rat kidney tissue, rat PC-12 cells, mouse kidney tissue, mouse NIH/3T3 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 intestine cancer tissue, rat kidney tissue, human placenta 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 confirmed staining (ICC/IF): U2OS cells.

Immunogen
Recombinant human Galectin 1 fragment (Ala2–Asp135), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 88% and 90%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes galectin-1 as secreted and also located in the cytoplasm. Tissue expression noted by UniProt (human): Expressed in placenta, maternal decidua and fetal membranes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
