Product Overview
This rabbit polyclonal antibody detects protein lin-28 homolog B (gene LIN28B) in human samples and is validated for Western blot, IHC and ELISA. The predicted molecular weight is 27.1 kDa, and the supplier reports an observed band at about 35 kDa.
LIN28B is an RNA-binding protein and paralog of LIN28A that suppresses production of let-7 microRNAs. It binds primary let-7 transcripts in the nucleus and keeps them from being processed, which supports stem cell self-renewal and fetal growth programs. LIN28B is studied in development, fetal hematopoiesis, puberty timing and cancers such as neuroblastoma.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human 293T cells, human HepG2 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): 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).
Immunogen
Recombinant human LIN28B fragment (Glu23–Lys249), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places protein lin-28 homolog B in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Expressed at high levels in the placenta and, at mucher lower, in testis and fetal liver. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
