Product Overview
This rabbit polyclonal antibody recognizes insulin-like growth factor 2 mRNA-binding protein 3 (gene IGF2BP3) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 63.7 kDa, and the supplier reports an observed band at about 64 kDa.
IGF2BP3 (also called IMP3) is an oncofetal RNA-binding protein that controls the stability and translation of target mRNAs, including CD44 and IGF2. It recognizes N6-methyladenosine (m6A)-modified transcripts and is expressed mainly during development and in many cancers, where it is often used as a tumor marker in research.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places insulin-like growth factor 2 mRNA-binding protein 3 in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Expressed in fetal liver, fetal lung, fetal kidney, fetal thymus, fetal placenta, fetal follicles of ovary and gonocytes of testis, growing oocytes, spermatogonia and semen (at protein level). 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).
